Python frozenset() Built in Function

Python frozenset() is a built-in function that returns an immutable set object. A set is a collection of unique and unordered elements that supports operations like union, intersection, difference, etc. A frozenset is like a set, but it cannot be modified or changed once created.

Here are some examples of how to use Python frozenset():

To create a frozenset from a list of fruits:

fruits = ["apple", "banana", "cherry"]
fset = frozenset(fruits)
print(fset)

Output:
frozenset({'apple', 'banana', 'cherry'})

To create an empty frozenset:

fset = frozenset()
print(fset)

Output:
frozenset()

To perform set operations with frozensets:

a = frozenset([1, 2, 3])
b = frozenset([3, 4, 5])
print(a.union(b)) # returns a new frozenset with elements from both a and b
print(a.intersection(b)) # returns a new frozenset with elements common to both a and b
print(a.difference(b)) # returns a new frozenset with elements in a but not in b

Output:
frozenset({1, 2, 3, 4, 5})
frozenset({3})
frozenset({1, 2})

Python chr() Built in Function

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...

Python The _ Operator

The _ operator in Python can have different meanings depending on the context. Here are some common uses of the _ operator: In the interactive interpreter, _ represents the result of the last expression evaluated. For example, if you type 2 + 3 and press enter, you will see 5 as the output. Then, if you type _ * 2 and press enter, you will see 10 as the output, because _ holds the value of 5. In a loop or a list comprehension, _ is often used as a placeholder for a variable that is not needed or used. For example, if you want to create a list of ten zeros, you can write [0 for _ in range(10)]. In internationalization (i18n) and localization (l10n) modules such as gettext, _ is used as an alias for a function that translates a string into another language. For example, if you write print(_(“Hello”)) and have a translation file that maps “Hello” to “Hola”, you will see “Hola” as the output. In some naming conventions, such as PEP 8 style guide for Python code, _ is used as a prefix for p...

Python bool() Built in Function

The Python bool() function returns a Boolean value (True or False) for a given object. The object can be any data type, such as numbers, strings, lists, tuples, sets, dictionaries, etc. The bool() function follows some rules to evaluate the truth value of an object: Any numeric value that is not zero is True. Zero (0) is False. Any non-empty string is True. Empty string (‘’) is False. Any non-empty collection (list, tuple, set, dictionary) is True. Empty collection ([], (), {}, set()) is False. None is always False. True and False are keywords that represent the Boolean values. Here are some examples of using bool() function: # Example 1: Convert different data types to Boolean with bool() function num = 10 print(bool(num)) # Output: True str = "Hello" print(bool(str)) # Output: True lst = [] print(bool(lst)) # Output: False none = None print(bool(none)) # Output: False # Example 2: Use bool() function in conditional statements name = input("Enter your name: ...

Python Printing Readable Results

There are different ways to print readable results in Python depending on what kind of data you have. For example: If you have a complex data structure such as a nested dictionary or list, you can use pprint module to format it nicely with indentation and line breaks. For example: import pprint data = {"name": "Alice", "age": 25, "hobbies": ["reading", "coding", "gaming"]} pprint.pprint(data) # Output: {'age': 25,  'hobbies': ['reading', 'coding', 'gaming'],  'name': 'Alice'} If you have a numerical data such as a matrix or an array, you can use numpy module to print it with precision and alignment. For example: import numpy as np matrix = np.array([[1.2345, 2.3456], [3.4567, 4.5678]]) np.set_printoptions(precision=2) print(matrix) # Output: [[1.23 2.35] [3.46 4.57]] If you have a text data such as a string or a paragraph, you can use f-strings to format it w...

Python One Liner Functions

Python one-liner functions are functions that can be written in a single line of code. They are often used to perform simple tasks or expressions without defining a named function. One way to create a one-liner function is to use the lambda keyword which creates an anonymous function that takes some arguments and returns a value. For example: # A lambda function that returns the square of a number square = lambda x: x**2 print(square(5)) # 25 # A lambda function that checks if a number is even is_even = lambda x: x%2 == 0 print(is_even(4)) # True Another way to create a one-liner function is to use the def keyword with a colon and an expression after it. This creates a named function that returns the value of the expression. For example: # A one-liner function that returns the sum of two numbers def add(x, y): return x + y print(add(3, 4)) # 7 # A one-liner function that reverses a string def reverse(s): return s[::-1] print(reverse("hello")) # olleh Python offers a one-l...
