The float() function in Python is used to convert a value into a floating point number, which is a number with a decimal point. For example, float(3) returns 3.0 and float(“5.5”) returns 5.5. You can also use float() with numbers that are too large or too small for Python to represent as integers, such as 1.82e310 or -32.54e100. Here are some examples of using float() in Python: # Example 1: Convert an integer to a float x = 25 y = float(x) print(y) # Output: 25.0 # Example 2: Convert a string to a float s = "12.34" z = float(s) print(z) # Output: 12.34 # Example 3: Convert an infinity value to a float inf = "infinity" w = float(inf) print(w) # Output: inf If you have any questions about this code, you can drop a line in comment .
The exec() function in Python is used to execute a dynamically generated code, which is a code that is created or modified at runtime. The exec() function takes a string or an object that contains a valid Python code and executes it as if it was written in a file. You can also pass a dictionary of global and local variables to the exec() function to modify the execution environment. Here are some examples of using exec() in Python: Execute a Python statement stored as a string: code = 'print("Hello, world!")' exec(code) Output: Hello, world! In this example, exec(code) executes the Python statement 'print("Hello, world!")', which prints the string "Hello, world!" to the console. Use exec() to execute a Python script stored in a file: with open('script.py', 'r') as file: code = file.read() exec(code) In this example, we open the file 'script.py', read its contents into a string, and then use exec() to execu...
The Python chr() function is used to get a string representing a character that corresponds to a Unicode code integer. For example, chr(97) returns the string 'a'. This function takes an integer argument and throws an error if it exceeds the range of 0 to 1,114,111. Here are some examples of using the chr() function in Python: # Get the character for ASCII code 65 print(chr(65)) # Output: A # Get the character for Unicode code point 1200 print(chr(1200)) # Output: Ұ # Get the characters for a list of integers codes = [71, 101, 101, 107, 115] chars = [chr(code) for code in codes] print(''.join(chars)) # Output: Geeks To print ‘Hello World’ using chr() , you can write: print(chr(72) + chr(101) + chr(108) + chr(108) + chr(111) + chr(32) + chr(87) + chr(111) + chr(114) + chr(108) + chr(100)) To print a list of all uppercase letters using chr() , you can write: letters = [] for i in range(65, 91): letters.append(chr(i)) print(letters) To print a smiley face emoji...
The Python encode() method is a string method that returns an encoded version of the given string using a specified encoding. Encoding is the process of converting a string into a sequence of bytes that can be stored or transmitted. If no encoding is specified, UTF-8 will be used by default. Here are some examples of using the encode() method in Python: To encode a string using UTF-8 encoding: title = "Python Programming" x = title.encode() print(x) Output: b'Python Programming' To encode a string using ASCII encoding and ignore any errors: str = "Hello World!" x = str.encode("ascii", "ignore") print(x) Output: b'Hello World!' To encode a string using base64 encoding: str = "Hello World!" x = str.encode("base64") print(x) Output: b'SGVsbG8gV29ybGQh\n' To encode a string containing non-ASCII characters using ISO 8859-1 encoding: str = "HËLLO" encode = str.encode("iso8859_1") pri...
The isalpha() method is a string method that returns True if all the characters in the string are alphabetic letters (a-z). For example: name = "Alice" print(name.isalpha()) # prints True The method returns False if the string contains any non-alphabetic characters, such as spaces, numbers, punctuation marks, symbols, etc. For example: name = "Alice 123" print(name.isalpha()) # prints False If you have any questions about this code, you can drop a line in comment .
