Replace string space with given character in Python

Table of Contents

In this tutorial we are going to learn writing python program to replace the string space with given character.

Problem Statement

For a given string we have to replace all the spaces with the character given by the user as an input.

For example:

Case 1:  If user is given the string value as ‘ques ol’,

                    and the character value inserted by user is ‘c’

                    then the output generated must be “quescol”.

Case 2:  If user is given the string value as ‘python sfun’,

                    and the character value inserted by user is ‘i’

                    then the output generated must be “pythonisfun”.

Our logic to replace a string with given character

  • In order to replace a string with any character, we need to take a string and a character as an input from the user using the ‘input()’ function.
  • Then, using for loop, we iterate through each element of string and search for “ “ (space).
  • If “ “(space) is found replace it with character.
  • Finally, the result will be returned as the output of our program.

Python code to replace the string space with given character

# Taking input from the user
string = input("Enter a string: ")
ch = input("Enter a character to replace spaces: ")

result = ''  # Empty string to store the result

# Iterating using a for loop
for i in string:
    if i == ' ':      # If space is found
        i = ch        # Replace it with the given character
    result += i       # Append the character to the result

# Printing the modified string
print("String after replacing spaces with", ch, "=", result)

Output:

Enter a string: quescol website
Enter a character to replace spaces: C
String after replacing spaces with C = quescolCwebsite
