❮ Previous Next ❯

A Python program to replace spaces in a string with a specified character using a loop-based approach.

Code Explanation Step by Step

Function Definition:
- replace_space(string, char) function is defined to replace spaces.
Initialize Empty String:
- new_string = "" is used to store the modified string.
Loop Through Characters:
- for s in string: iterates through each character in the string.
Check for Space:
- if s == " ": checks if the character is a space.

def replace_space(string, char):

    new_string = ""  

    for s in string:

        if s == " ":

            new_string += char  

        else:

            new_string += s
