Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
Collections.UserString in Python
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:
Python3
# Python program to demonstrate# string# Creating a String # with single QuotesString1 = 'Welcome to the Geeks World'print("String with the use of Single Quotes: ")print(String1) # Creating a String# with double QuotesString1 = "I'm a Geek"print("\nString with the use of Double Quotes: ")print(String1) |
Output:
String with the use of Single Quotes: Welcome to the Geeks World String with the use of Double Quotes: I'm a Geek
Note: For more information, refer to Python String
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:
Python3
# Python program to demonstrate# userstringfrom collections import UserStringd = 12344# Creating an UserDictuserS = UserString(d)print(userS.data)# Creating an empty UserDictuserS = UserString("")print(userS.data) |
Output:
12344
Example 2:
Python3
# Python program to demonstrate# userstring from collections import UserString # Creating a Mutable Stringclass Mystring(UserString): # Function to append to # string def append(self, s): self.data += s # Function to remove from # string def remove(self, s): self.data = self.data.replace(s, "") # Driver's codes1 = Mystring("Geeks")print("Original String:", s1.data)# Appending to strings1.append("s")print("String After Appending:", s1.data)# Removing from strings1.remove("e")print("String after Removing:", s1.data) |
Output:
Original String: Geeks String After Appending: Geekss String after Removing: Gkss
