PzStr - Python String Extension

PzStr is a Python string extension that adds additional functionality and methods to the built-in str class. It aims to provide a more convenient way to work with strings by offering various methods for manipulation and transformation.

Features

• Extends the built-in str class with additional methods.
• Methods for reversing, removing, and modifying strings.
• Functional-style methods for filtering, mapping, and iterating over characters.
• Access to length, first, and last properties.
• Seamless integration with existing strings.

Installation

Simply copy the PzStr class into your Python project to start using it:

Usage

Create a PzStr object

my_string = PzStr("Hello, world!")

Reverse the string

reversed_string = my_string.reverse()
print("Reversed:", reversed_string)  # Output: Reversed: !dlrow ,olleH

Remove a substring

new_string = my_string.remove("o")
print("Without 'o':", new_string)  # Output: Without 'o': Hell, wrld!

Get a substring

substring = my_string.substring(7, 12)
print("Substring:", substring)  # Output: Substring: world!

Check if the string is empty or not

is_empty = my_string.isEmpty()
print("Is Empty?", is_empty)  # Output: Is Empty? False

Convert the string to a list of characters

char_list = my_string.asList()
print("Character List:", char_list)  # Output: Character List: ['H', 'e', 'l', 'l', ',', ' ', 'w', 'o', 'r', 'l', 'd', '!']

Remove characters that meet a condition

my_string.removeWhere(lambda char: char == "l")
print("After Removing 'l':", my_string)  # Output: After Removing 'l': Heo, word!

Iterate over characters and print them

my_string.forEach(lambda char: print(char))
# Output:
# H
# e
# o
# ,
#  
# w
# r
# d
# !

Map characters to uppercase

my_string.where(lambda char: char != " ", lambda char: char.upper())
print("Uppercased:", my_string)  # Output: Uppercased: HEO, WRD!

Insert "Awesome" at index 2

my_string.insert("Awesome", 2)
print(my_string)  # Output: HeAwesomello, world!

Insert "X" wherever the character is 'o'

my_string.insertWhere("X", lambda item: item == 'o')
print(my_string)  # Output: HeAwesoXmelloX, woXrld!

Access the length of the string

string_length = my_string.length
print("Length:", string_length)  # Output: Length: 10

Access the first and last characters

first_char = my_string.first
last_char = my_string.last
print("First Char:", first_char)  # Output: First Char: H
print("Last Char:", last_char)    # Output: Last Char: D
