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

In this article, we’ll learn how to use Python to remove the first occurrence of a character in a string. The aim is to remove the first occurrence of a character in a string. To begin, locate the character in the string and confirm that it is the first occurrence. Finally, remove the character from the string and display the result.

Examples:

Example1:

Input:

Given String =goodmorningthisisbtechgeekspython
Given Character =s

Output:

The Given string after removing first occurence of the character [ s ] is goodmorningthisisbtechgeekspython
The Given string after removing first occurence of the character [ s ] is goodmorningthiisbtechgeekspython

Example2:

Input:

Given String =hellothisisbtechgeeks
Given Character =e

Output:

The Given string after removing first occurence of the character [ e ] is hellothisisbtechgeeks
The Given string after removing first occurence of the character [ e ] is hllothisisbtechgeeks

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

Below are the ways to remove the first occurrence of the given character in a string in Python.

Using For loop(Static Input)
Using For loop(User Input)

Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.

Method #1: Using For Loop (Static Input)

Approach:

Give the string as static input and store it in a variable.
Give the character as static input and store it in another variable.
Calculate the length of the string using the len() function.
Loop in the characters of the string using the For loop.
Check if the iterator character is equal to the given character using the if conditional statement and == operator.
Initialize the resultstrng with the given string from 0 to iterator value concatenated with iterator value +1 to the length of the given string.
Break the For loop using the break keyword.
Print the Result.
The Exit of the Program.

Below is the implementation:

# Give the string as static input and store it in a variable.
gvnstrng = 'hellothisisbtechgeeks'
# Give the character as static input and store it in another variable.
gvnchar = 'e'
# Calculate the length of the string using the len() function.
strnglength = len(gvnstrng)
# Loop in the characters of the string using the For loop.
for i in range(strnglength):
  # Check if the iterator character is equal to the given character
  # using the if conditional statement and == operator.
    if(gvnstrng[i] == gvnchar):
      # Initialize the resultstrng with the given string
      # from 0 to iterator value concatenated
      # with iterator value +1 to the length of the given string.
        reesultvalu = gvnstrng[0:i] + gvnstrng[i + 1:strnglength]
        # Break the For loop using the break keyword.
        break
# Print the Result.
print(
    'The Given string after removing first occurence of the character [', gvnchar, '] is', gvnstrng)
print(
    'The Given string after removing first occurence of the character [', gvnchar, '] is', reesultvalu)

Output:

The Given string after removing first occurence of the character [ e ] is hellothisisbtechgeeks
The Given string after removing first occurence of the character [ e ] is hllothisisbtechgeeks

Method #2: Using For Loop (User Input)

Approach:

Give the string as user input using the input() function and store it in a variable.
Give the character as user input using the input() function and store it in another variable.
Calculate the length of the string using the len() function.
Loop in the characters of the string using the For loop.
Check if the iterator character is equal to the given character using the if conditional statement and == operator.
Initialize the resultstrng with the given string from 0 to iterator value concatenated with iterator value +1 to the length of the given string.
Break the For loop using the break keyword.
Print the Result.
The Exit of the Program.

Below is the implementation:

# Give the string as user input using the input() function and store it in a variable.
gvnstrng = input('Enter some random given string = ')
# Give the character as user input using the input() function and store it in another variable.
gvnchar = input('Enter some random character = ')
# Calculate the length of the string using the len() function.
strnglength = len(gvnstrng)
# Loop in the characters of the string using the For loop.
for i in range(strnglength):
  # Check if the iterator character is equal to the given character
  # using the if conditional statement and == operator.
    if(gvnstrng[i] == gvnchar):
      # Initialize the resultstrng with the given string
      # from 0 to iterator value concatenated
      # with iterator value +1 to the length of the given string.
        reesultvalu = gvnstrng[0:i] + gvnstrng[i + 1:strnglength]
        # Break the For loop using the break keyword.
        break
# Print the Result.
print(
    'The Given string after removing first occurence of the character [', gvnchar, '] is', gvnstrng)
print(
    'The Given string after removing first occurence of the character [', gvnchar, '] is', reesultvalu)

Output:

Enter some random given string = goodmorningthisisbtechgeekspython
Enter some random character = s
The Given string after removing first occurence of the character [ s ] is goodmorningthisisbtechgeekspython
The Given string after removing first occurence of the character [ s ] is goodmorningthiisbtechgeekspython
