Reverse Each Word in a String Python

We will develop a program to reverse each word in a string python. In this article, we are using the split() function, list comprehension, and join() function to reverse each word of a string in Python. The split() method splits the string from the specified separator and returns a list object with string elements. The join() method takes all items in an iterable and joins them into one string. A string must be specified as the separator. List comprehensions provide a concise way to create lists.

Example of reverse each word in a string:-
String: know program is best to learn programming
Reverse: wonk margorp si tseb ot nrael gnimmargorp

Reverse Each Word of a String in Python

We will take a string while declaring the variables. Then, find the reverse of each word in a string using the for loop. Finally, the result will be displayed on the screen.

# Python program to reverse each word in a string

# take inputs
string = 'Know Program'

# splitting the string into list of words
words = string.split(' ')
# reversing each word and creating a new list of words
reverseWords = [word[::-1] for word in words]
# joining the new list of words to for a new string
reverseString = " ".join(reverseWords)

# print reverse of each word in a string
print('The reverse is', reverseString)

Output:-

The reverse is wonK margorP

Python Program to Reverse Each Word in a String

In the previous program, inputs are hardcoded in the program but in this program, input will be provided by the user.

# Python program to reverse each word in a string

# take inputs
string = input('Enter the string: ')

# splitting the string into list of words
words = string.split(' ')
# reversing each word and creating a new list of words
reverseWords = [word[::-1] for word in words]
# joining the new list of words to for a new string
reverseString = " ".join(reverseWords)

# print reverse of each word in a string
print('The reverse is', reverseString)

Output for the input values test-case-1:-

Enter the string: Welcome to Know Program
The reverse is emocleW ot wonK margorP

Output for the input values test-case-2:-

Enter the string: reverse each word in a string python
The reverse is esrever hcae drow ni a gnirts nohtyp

Reversing Each Word in a String in Python

This method is similar to the above method, but rather a shorthand method. In this program, reverse each word of the string in one line.

# Python program to reverse each word in a string

# take inputs
string = input('Enter the string: ')

# reverse each word in a string
reverseString = " ".join(word[::-1] for word in string.split(" "))

# print reverse of each word in a string
print('The reverse is', reverseString)

Output:-

Enter the string: Python Program
The reverse is nohtyP margorP

Reverse Each Word in a String Python

We can also take the help of a function to reverse each word in a string. A function is a block of code that performs a specific task.

# Python program to reverse each word in a string

def reverseWords(s):  #user-defined function
    return " ".join(word[::-1] for word in s.split(" "))

# take inputs
string = input('Enter the string: ')

# calling function and display result
print('The reverse is', reverseWords(string))

Output for the input values test-case-1:-

Enter the string: My name is guddu kumar singh
The reverse is yM eman si uddug ramuk hgnis

Output for the input values test-case-2:-

Enter the string: know program is best to learn programming
The reverse is wonk margorp si tseb ot nrael gnimmargorp
