In the Python program, we will learn how to replace a character in a given string. Here we used the python built-in function replace() to replace a character in a string and another way to do it is using loops.
Here is the source code of the program to replace a character in a given string.
Python Program to Replace a Character in a Given String Using replace() function
# Python Program to Replace a Character in a Given String Using replace() function
# Take the Input From the User
str1 = input("Enter the String: ")
ch = input("Enter the Character: ")
newch = input("Enter the New Character: ")
str2 = str1.replace(ch, newch)
print("\nOriginal String : ", str1)
print("Modified String : ", str2)

str1 = input("Enter the String: ")
ch = input("Enter the Character: ")
newch = input("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)
