Strings are the arrays of bytes representing Unicode characters. However, Python does not support the character data type. A character is a string of length one.
Example:
# Python program to demonstrate
# string
# Creating a String
# with single Quotes
String_1 = 'Welcome to the prutor World'
print("String with the use of Single Quotes: ")
print(String_1)
# Creating a String
# with double Quotes
String_1 = "I'm a prutor"
print("nString with the use of Double Quotes: ")
print(String_1)
Output:
String with the use of Single Quotes:
Welcome to the prutor World
String with the use of Double Quotes:
I'm a prutor

Collections.UserString
Python supports a String like a container called UserString present in the collections module. This class acts as a wrapper class around the string objects. This class is useful when one wants to create a string of their own with some modified functionality or with some new functionality. It can be considered as a way of adding new behaviors for the string. This class takes any argument that can be converted to string and simulates a string whose content is kept in a regular string. The string is accessible by the data attribute of this class.
Syntax:
collections.UserString(seq)
Example 1:
# Python program to demonstrate
# userstring
from collections import UserString
d = 12344
# Creating an UserDict
userS = UserString(d)
print(userS.data)
# Creating an empty UserDict
userS = UserString("")
print(userS.data)
Output:
12344
Example 2:
# Python program to demonstrate
# userstring
from collections import UserString
# Creating a Mutable String
class Mystring(UserString):
# Function to append to
# string
def append(self, s):
self.data += s
# Function to rmeove from
# string
def remove(self, s):
self.data = self.data.replace(s, "")
# Driver's code
s1 = Mystring("prutor")
print("Original String:", s1.data)
# Appending to string
s1.append("s")
print("String After Appending:", s1.data)
# Removing from string
s1.remove("e")
print("String after Removing:", s1.data)
Output:
Original String: prutor
String After Appending: prutors
String after Removing: prutors
