To remove the first occurrence of character from string in python; In this python tutorial, we would love to share with you several python programs to find and remove the first occurrence of a character in a string using For Loop, while loop, and functions.
How to remove first occurrence of character from string in python
Follow the below given 3 programs to find and remove first occurrence of a character in a string in python:
- Python Program 1: To Remove the First Occurrence of a Character in a String
- Python Program 2: To Delete the First Occurrence of a Character in a String
- Python Program 3: To Delete First Occurrence of a String Character
Python Program 1: to Remove the First Occurrence of a Character in a String
- Allow the user to enter a string and a character.
- Next, it finds and removes the first occurrence of that character inside a given string using For Loop.
- Use For Loop to iterate each character in a String.
- Inside the For Loop, use If Statement to check the character is equal to ch or not. If true, it uses the string slice index to remove that character and Break statement to exit the loop.
# Python Program to Remove the 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)
After executing the program, the output will be:
Please enter your own String : hello Please enter your own Character : o Original String : hello Final String : hell
Python Program 2: to Delete the First Occurrence of a Character in a String
- Allow the user to enter a string and a character.
- Next, it finds and removes the first occurrence of that character inside a given string using while Loop.
- Use while Loop to iterate each character in a String.
- Inside the while Loop, use If Statement to check the character is equal to ch or not. If true, it uses 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) 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)
After executing the program, the output will be:
Please enter your own String : string Please enter your own Character : g Original String : string Final String : strin
Python Program 3: to Delete First Occurrence of a String Character
# 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))
After executing the program, the output will be:
Please enter your own String : world Please enter your own Character : d Original String : world Final String : worl
