How to use list comprehension and join method In Python

Algorithm:

Initialize the given string “Str”.
Create a list “x” by iterating through each character in the string “Str” using a list comprehension.
Remove the last character from the list “x” using the pop() method.
Join the characters in the list “x” back to form a string and store it in “x”.
Print the resulting string “x”.

Python3

#Python program to Remove Last character from the string
Str = "w3wiki"
x = "".join([Str[i] for i in range(len(Str)-1)])
print(x)

Output

GeeksForGeek

Time Complexity: O(n), where n is the length of the input string “Str”.
Auxiliary Space: O(n), where n is the length of the Out[ut string “x”.

Python program to Remove Last character from the string

Given a string, the task is to write a Python program to remove the last character from the given string.

Example:

Input: “w3wiki”
Output: “GeeksForGeek”

Input: “1234”
Output: “123”
Explanation: Here we are removing the last character of the original string.
