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

Write a Python program to Remove First 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 First 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 the first occurrence of that character inside a given string using For Loop.

First, we used For Loop to iterate each and every character 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, and Break statement to exit the loop.

# Python Program to Remove First 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]
        break
 
print("Original String :  ", string)
print("Final String :     ", string2)

Python Program to Delete First Occurrence of a Character in a String Example 2

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

# Python Program to Remove First 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]
        break
    i = i + 1
 
print("Original String :  ", string)
print("Final String :     ", string2)

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

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

# Python Program to Remove First Occurrence of a Character in a String
 
def removeFirstOccur(string, char):
    string2 = ''
    length = len(string)

    for i in range(length):
        if(string[i] == char):
            string2 = string[0:i] + string[i + 1:length]
            break
    return string2

str1 = input("Please enter your own String : ")
char = input("Please enter your own Character : ")

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