Reverse Words in a String Python

We will develop a program to reverse words in a string python. In this article, we are using the split(), reversed(), and join() functions to reverse the words of a string in Python. The split() method splits the string from the specified separator and returns a list object with string elements.

The reversed() function allows us to process the items in a sequence in reverse order. It accepts a sequence and returns an iterator. The join() method takes all items in an iterable and joins them into one string. A string must be specified as the separator.

Example of reverse words in a string:-
String: Know Program is best to learn programming
Reverse: programming learn to best is Program Know

Python Program to Reverse Words in a String

We will take a string while declaring the variables. Then, find the reverse of words in a string using reversed() function. Finally, the result will be displayed on the screen.

# Python program to reverse words in a string

# take inputs
string = 'Know Program'

# splitting the string into list of words
words = string.split(' ')
# reversing the split string list and join using space
reverseString = " ".join(reversed(words))

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

Output:-

The reverse is Program Know

Reverse Words in a String Python

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 words in a string

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

# splitting the string into list of words
words = string.split(' ')
# reversing the split string list and join using space
reverseString = " ".join(reversed(words))

# 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 Program Know to Welcome

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

Enter the string: Reverse words of a string
The reverse is string a of words Reverse

Reverse Words in a String Python using Function

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

# Python program to reverse words in a string

def reverseWords(s):  #user-defined function

   # splitting the string into list of words
   words = string.split(' ')
   
   # reversing the split string list and join using space
   reverse = " ".join(reversed(words))
   return reverse

# 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 Singh Kumar Guddu is Name My

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

Enter the string: Know Program is best to learn programming
The reverse is programming learn to best is Program Know
