The Python center() method is a string method that returns a new string that is padded with a specified character (space by default) on both sides of the original string. The length of the new string is specified by a parameter. Here is an example of how to use the center() method to align a string with 20 characters and use # as the padding character: str = "Hello Javatpoint" str2 = str.center(20,'#') print("Old value:", str) print("New value:", str2) Output: Old value: Hello Javatpoint New value: ##Hello Javatpoint## If you have any questions about this code, you can drop a line in comment .

The casefold() method converts all characters of the string into lowercase letters and returns a new string. This method is similar to lower() , but it also performs more aggressive case conversions for some characters that do not have a direct lowercase equivalent. For example: text = "pYtHon" # convert all characters to lowercase lowercased_string = text.casefold() print(lowercased_string) # Output: python color1 = 'weiß' # German word for white color2 = 'weiss' print(color1 == color2) # False print(color1.lower() == color2.lower()) # False print(color1.casefold() == color2.casefold()) # True If you have any questions about this code, you can drop a line in comment .

The capitalize() method converts the first character of a string to an uppercase letter and all other alphabets to lowercase. For example: sentence = "i love PYTHON" # converts first character to uppercase and others to lowercase capitalized_string = sentence.capitalize() print(capitalized_string) # Output: I love python If you have any questions about this code, you can drop a line in comment .

The Python zfill() method is used to return a string where zeros (0) are added at the beginning of the string until it reaches a specified length. It returns a new string with the zero-filled version of the original string. For example: text = "Hello world" result = text.zfill(15) print(result) # Output: 00000Hello world You can also use zfill() on a string that contains numbers or symbols. The zfill() method does not affect them and only adds zeros before them. For example: text = "10.00" result = text.zfill(8) print(result) # Output: 00010.00 If you have any questions about this code, you can drop a line in comment .

The Python translate() method is used to return a string where each character is mapped to its corresponding character as per a translation table. It returns a new string with the translated characters. To use translate() , you need to first create a translation table using the maketrans() method. The maketrans() method takes two parameters: a string of characters that need to be replaced, and a string of characters that will replace them. For example: text = "Hello Sam!" # create a translation table that replaces "S" with "P" table = text.maketrans("S", "P") # apply the translation table on the text result = text.translate(table) print(result) # Output: Hello Pam! You can also use translate() to delete certain characters from a string by passing a third parameter to the maketrans() method. The third parameter is a string of characters that will be removed from the original string. For example: text = "Hello Sam!" # crea...

The Python upper() method is used to return a string where all characters are in upper case. It returns a new string with the upper cased version of the original string. For example: text = "Hello my friends" result = text.upper() print(result) # Output: HELLO MY FRIENDS You can also use upper() on a string that contains numbers or symbols. The upper() method ignores them and only converts the alphabetic characters to upper case. For example: text = "heLLo wORld 123 !@#" result = text.upper() print(result) # Output: HELLO WORLD 123 !@# If you have any questions about this code, you can drop a line in comment .  

The Python title() method is used to return a string where the first character in every word is upper case, and the remaining characters are lower case. It returns a new string with the title cased version of the original string. For example: text = "hello world" result = text.title() print(result) # Output: Hello World You can also use title() on a string that contains numbers or symbols. The first letter after any number or symbol will be converted to upper case. For example: text = "234 k3l2 *43 fun" result = text.title() print(result) # Output: 234 K3L2 *43 Fun If you have any questions about this code, you can drop a line in comment .

The Python swapcase() method is used to convert all uppercase characters to lowercase and vice versa of a given string. It returns a new string with the cases swapped. For example: text = "Hello World" result = text.swapcase() print(result) # Output: hELLO wORLD You can also use swapcase() on a string that contains a mix of upper and lower case characters. All cases will be reversed when swapcase() method is called. For example: text = "HeLLo WoRld" result = text.swapcase() print(result) # Output: hEllO wOrLD If you have any questions about this code, you can drop a line in comment .

The Python strip() method is used to remove any leading and trailing characters from a string. By default, it removes whitespace characters (such as space, tab, newline) from both ends of the string. For example: text = "  Hello world!  " result = text.strip() print(result) # Output: Hello world! You can also pass an optional parameter characters to the strip() method. It specifies a set of characters that you want to remove from both ends of the string. For example: text = ",,,,,rrttgg.....banana....rrr" result = text.strip(",.grt") print(result) # Output: banana  If you have any questions about this code, you can drop a line in comment .

The Python startswith() method is used to check if a string starts with a specified value. It returns True if the string starts with the value, otherwise False. For example: text = "Hello, welcome to my world." result = text.startswith("Hello") print(result) # Output: True You can also pass optional parameters start and end to the startswith() method. They specify the start and end positions of the string where the check is performed. For example: text = "Hello, welcome to my world." result = text.startswith("wel", 7, 20) print(result) # Output: True If you have any questions about this code, you can drop a line in comment .

The Python splitlines() method is used to break a string at line boundaries, such as \n (newline), \r (carriage return), \r\n (carriage return + newline) and others. It returns a list of the split strings. For example: sentence = "This is a\nmulti-line\nstring." result = sentence.splitlines() print(result) # Output: ['This is a', 'multi-line', 'string.'] You can also pass an optional parameter keeplinebreaks to the splitlines() method. If it is True, then the line breaks are preserved as part of the split strings. For example: sentence = "This is another\r\nmulti-line\r\nstring." result = sentence.splitlines(True) print(result) # Output: ['This is another\r\n', 'multi-line\r\n', 'string.'] If you have any questions about this code, you can drop a line in comment .

The Python split() method is a string method that splits a string into a list of substrings, using a specified separator as the delimiter. It has the following syntax: string.split(separator, maxsplit) where separator is an optional parameter that specifies the string to split on (default is any whitespace), maxsplit is an optional parameter that specifies how many splits to do from the left (default is -1, which means all possible splits). The split() method returns a list of substrings after splitting the string. Here are some examples of using the Python split() method: # Example 1: Split a string by space mystr = 'welcome to the jungle' result = mystr.split() print(result) # Output: ['welcome', 'to', 'the', 'jungle'] # Example 2: Split a string by comma and space mystr = 'hello, my name is Peter, I am 26 years old' result = mystr.split(', ') print(result) # Output: ['hello', 'my name is Peter', 'I am 26 ...

The Python rstrip() method is a string method that removes any trailing characters (characters at the end of a string) from a string. It has the following syntax: string.rstrip(characters) where characters is an optional parameter that specifies a set of characters to be removed (default is any whitespace). The rstrip() method returns a copy of the string with trailing characters removed. Here are some examples of using the Python rstrip() method: # Example 1: Remove trailing whitespace mystr = 'Hello World   ' result = mystr.rstrip() print(result) # Output: 'Hello World' # Example 2: Remove trailing commas and periods mystr = 'apple,banana,cherry,,,,.' result = mystr.rstrip(',.') print(result) # Output: 'apple,banana,cherry' # Example 3: Remove trailing '#' mystr = 'Java and C#' result = mystr.rstrip('#') print(result) # Output: 'Java and C' If you have any questions about this code, you can drop a line in com...

The Python rsplit() method is a string method that splits a string into a list of substrings, starting from the right end of the string and using a specified separator as the delimiter. It has the following syntax: string.rsplit(separator, maxsplit) where separator is an optional parameter that specifies the string to split on (default is any whitespace), maxsplit is an optional parameter that specifies how many splits to do from the right (default is -1, which means all possible splits). The rsplit() method returns a list of substrings after splitting the string. Here are some examples of using the Python rsplit() method: # Example 1: Split a string by comma mystr = 'apple,banana,cherry' result = mystr.rsplit(',') print(result) # Output: ['apple', 'banana', 'cherry'] # Example 2: Split a string by space with maxsplit=2 mystr = 'This is a sample sentence' result = mystr.rsplit(' ', 2) print(result) # Output: ['This is a...

The Python rpartition() method is a string method that splits a string at the last occurrence of a specified separator and returns a tuple containing three elements: the part before the separator, the separator itself, and the part after the separator. It has the following syntax: string.rpartition(separator) where separator is a string that specifies where to split the string. If separator is found in the string, rpartition() returns a tuple with three elements. If separator is not found in the string, rpartition() returns a tuple with two empty strings and the original string. Here are some examples of using the Python rpartition() method: # Example 1: Split a string at 'and' mystr = 'Do it now and keep it simple' result = mystr.rpartition('and') print(result) # Output: ('Do it now ', 'and', ' keep it simple') # Example 2: Split a string at '-' mystr = '2021-03-06' result = mystr.rpartition('-') print(result)...

The Python rjust() method is a string method that right aligns a string by padding it with a specified character (space by default) to a given width. It has the following syntax: string.rjust(width, fillchar) where width is the length of the resulting string, fillchar is an optional parameter that specifies the character to fill the padding (default is space). The rjust() method returns a new string that is right justified with the given width and fillchar. Here are some examples of using the Python rjust() method: # Example 1: Right justify a string with spaces mystr = 'Hello' result = mystr.rjust(10) print(result) # Output: '     Hello' # Example 2: Right justify a string with dashes mystr = 'World' result = mystr.rjust(10, '-') print(result) # Output: '-----World' # Example 3: Right justify a number with zeros num = 42 result = str(num).rjust(5, '0') print(result) # Output: '00042' If you have any questions about this code, ...

The Python rindex() method is a string method that finds the last occurrence of a specified value in a string. It has the following syntax: string.rindex(value, start, end) where value is the substring to be searched for, start and end are optional parameters that specify the range of indexes to search within (default is the whole string). The rindex() method returns an integer value that represents the highest index where value is found. If value is not found, it raises a ValueError exception. Here are some examples of using the Python rindex() method: # Example 1: Find the last occurrence of 'l' in 'Hello World' greet = 'Hello World' index = greet.rindex('l') print(index) # Output: 9 # Example 2: Find the last occurrence of 'tutorials' in a sentence mystr = 'tutorialsteacher is a free tutorials website' index = mystr.rindex('tutorials') print(index) # Output: 25 # Example 3: Find the last occurrence of 'o' between ind...

The Python rfind() method is a string method that finds the last occurrence of a specified value in a string. It has the following syntax: string.rfind(value, start, end) where value is the substring to be searched for, start and end are optional parameters that specify the range of indexes to search within (default is the whole string). The rfind() method returns an integer value that represents the highest index where value is found. If value is not found, it returns -1. Here are some examples of using the Python rfind() method: # Example 1: Find the last occurrence of 'l' in 'Hello World' greet = 'Hello World' index = greet.rfind('l') print(index) # Output: 9 # Example 2: Find the last occurrence of 'tutorials' in a sentence mystr = 'tutorialsteacher is a free tutorials website' index = mystr.rfind('tutorials') print(index) # Output: 25 # Example 3: Find the last occurrence of 'o' between index 0 and 5 greet = 'H...

The Python replace() method is a string method that replaces a specified phrase with another specified phrase. It has the following syntax: string.replace(oldvalue, newvalue, count) where oldvalue is the substring to be replaced, newvalue is the new substring that will replace it, and count is an optional parameter that specifies how many occurrences of oldvalue to replace (default is all occurrences). Here are some examples of using the Python replace() method: # Example 1: Replace all occurrences of 'lemons' with 'oranges' mystr = 'lemons, bananas, lemons, apples, cherries' newstr = mystr.replace('lemons', 'oranges') print(newstr) # Output: oranges, bananas, oranges, apples, cherries # Example 2: Replace only one occurrence of 'apples' with 'pears' mystr = 'lemons, bananas, lemons, apples, cherries' newstr = mystr.replace('apples', 'pears', 1) print(newstr) # Output: lemons, bananas, lemons, pears cherr...

The partition() method is a string method that splits the string at the first occurrence of a given separator and returns a tuple containing three elements: the part before the separator, the separator itself, and the part after the separator. If the separator is not found in the string, then the tuple will contain the original string and two empty strings. Here are some examples of using the partition() method: # example 1: split a string by a word txt = "I could eat bananas all day" x = txt.partition("bananas") print(x) # ('I could eat ', 'bananas', ' all day') # example 2: split a string by a symbol txt = "#1 Harbor Side" x = txt.partition("1") print(x) # ('#', '1', ' Harbor Side') # example 3: split a string by an empty separator txt = "Hello World" x = txt.partition("") print(x) # ValueError: empty separator # example 4: split a string by a non-existing separator txt = ...
