by

In this article, we will show you, How to write a Python program to Replace Blank Space with Hyphen in a String using replace function, and For Loop with practical example.

TIP: Please refer String article to understand everything about Strings.

Python Program to Replace Blank Space with Hyphen in a String Example 1

This python program allows the user to enter a string. Next, we used built-in string function called replace to replace empty space with hyphen.

# Python program to Replace Blank Space with Hyphen in a String
 
str1 = input("Please Enter your Own String : ")

str2 = str1.replace(' ', '_')

print("Original String :  ", str1)
print("Modified String :  ", str2)

Python Program to Replace Blank Space with Hyphen in a String Example 2

In this program, we used For Loop to iterate each and every character in a String. Inside the For Loop, we are using If Statement to check whether the character is empty or blank space. If true, repack it with _

# Python program to Replace Blank Space with Hyphen in a String
 
str1 = input("Please Enter your Own String : ")

str2 = ''

for i in range(len(str1)):
    if(str1[i] == ' '):
        str2 = str2 + '_'
    else:
        str2 = str2 + str1[i]
        
print("Modified String :  ", str2)

Python Program to Replace Empty Space with Hyphen in a String Example 3

This program is same as above example. However, we are using For Loop with Object

# Python program to Replace Blank Space with Hyphen in a String
 
str1 = input("Please Enter your Own String : ")

str2 = ''

for i in str1:
    if(i == ' '):
        str2 = str2 + '_'
    else:
        str2 = str2 + i
        
print("Modified String :  ", str2)
