Write a Python program to Replace Characters in a String using the replace function and For Loop with an example.
Python Program to Replace Characters in a String 1
This program allows the user to enter a string, character to replace, and new character you want to replace with. Next, we used a built-in string function called replace to replace user given character with a new character.
# Python program to Replace Characters in a String str1 = input("Please Enter your Own String : ") ch = input("Please Enter your Own Character : ") newch = input("Please Enter the New Character : ") str2 = str1.replace(ch, newch) print("\nOriginal String : ", str1) print("Modified String : ", str2)

Program to Replace String Characters Example 2
In this program program, we used For Loop to iterate every character in a String. Inside the For Loop, we are using If Statement to check whether the String character is equal to ch or not. If true, Python replace it with Newch
# Python program to Replace Characters in a String str1 = input("Please Enter your Own String : ") ch = input("Please Enter your Own Character : ") newch = input("Please Enter the New Character : ") str2 = '' for i in range(len(str1)): if(str1[i] == ch): str2 = str2 + newch else: str2 = str2 + str1[i] print("\nOriginal String : ", str1) print("Modified String : ", str2)

Python Replace Characters in a String Example 3
This Python replaces string Characters code is the same as the above example. However, we are using For Loop with Object.
# Python program to Replace Characters in a String str1 = input("Please Enter your Own String : ") ch = input("Please Enter your Own Character : ") newch = input("Please Enter the New Character : ") str2 = '' for i in str1: if(i == ch): str2 = str2 + newch else: str2 = str2 + i print("\nOriginal String : ", str1) print("Modified String : ", str2)
