Python Program to Remove Last Occurrence of a Character in a String

Write a Python program to Remove Last Occurrence of a Character in a String using For Loop, while loop, and functions with example.

TIP: Please refer String article to understand everything about Strings.

Python Program to Remove Last Occurrence of a Character in a String Example 1

This python program allows the user to enter a string, and a character. Next, it will find and remove last character occurrence inside a given string using For Loop.

First, we used For Loop to iterate characters in a String. Inside the For Loop, we are using If Statement to check whether the character is equal to ch or not. If true, it use the string slice index to remove that character.

NOTE: Even though, if it find multiple matches, it will until it find the last character. Because, we are not using Break statement to exit from loop.

# Python Program to Remove Last Occurrence of a Character in a String
 
string = input("Please enter your own String : ")
char = input("Please enter your own Character : ")

string2 = ''
length = len(string)

for i in range(length):
    if(string[i] == char):
        string2 = string[0:i] + string[i + 1:length]
 
print("Original String :  ", string)
print("Final String :     ", string2)

OUTPUT

Python Program to Delete Last Character Occurrence in a String Example 2

This remove last occurrence of a character program is same as above. However, we just replaced the For Loop with While Loop.

# Python Program to Remove Last Occurrence of a Character in a String
 
string = input("Please enter your own String : ")
char = input("Please enter your own Character : ")

string2 = ''
length = len(string)
i = 0

while(i < length):
    if(string[i] == char):
        string2 = string[0 : i] + string[i + 1 : length]
    i = i + 1
 
print("Original String :  ", string)
print("Final String :     ", string2)

OUTPUT

Python Program to Delete Last Occurrence of a String Character Example 3

This program is same as first example, but this time we used Functions concept to separate the logic.

# Python Program to Remove Last Occurrence of a Character in a String
 
def removeLastOccur(string, char):
    string2 = ''
    length = len(string)
    i = 0

    while(i < length):
        if(string[i] == char):
            string2 = string[0 : i] + string[i + 1 : length]
        i = i + 1
    return string2
 
str1 = input("Please enter your own String : ")
char = input("Please enter your own Character : ")

print("Original String :  ", str1)
print("Final String :     ", removeLastOccur(str1, char))
