Program to Reverse each Word in a Sentence

Python Program to Reverse each Word in a Sentence

by

In the previous article, we have discussed Python Program to Get the Position of Max Value in a List
Given a Sentence, the task is to Reverse each Word in a Given Sentence.

Split method:

Splitting a string into a list is accomplished by the split() method. It is a built-in Function in python.

join function:

The join() method is a string method that returns a string containing the elements of a sequence that have been joined by a string separator.

Examples:

Example 1:

Input:

Given String = Hello this is btechgeeks

Output:

The Reverse of each word of the above given sentence =  olleH siht si skeeghcetb

Example 2:

Input:

Given String = Good Morning btechGeeks

Output:

The Reverse of each word of the above given sentence = dooG gninroM skeeGhcetb

Program to Reverse each Word in a Sentence

Below are the ways to Reverse each Word in a Sentence.

Method #1: Using split() Method (Static Input)

Approach:

  • Give the string as static input and store it in a variable.
  • Split the words of the given string to a list of words using the built-in split() function and store it in another variable.
  • Traverse in the above-Given List of words using For Loop.
  • Inside the Loop, Reverse each word of the list Using the Slicing method and store it in a variable.
  • Join all the reversed words of a given sentence using the built-in join( ) function and store it in another variable.
  • Print the reversed Sentence of each word of a given String.
  • The Exit of the program.

Below is the implementation:

# Give the string as static input and store it in a variable.
strng = "Hello this is btechgeeks"
# Split the words of the given string to a list of words using the built-in split() function and store it in another variable.
splt_wrds = strng.split()
# Traverse in the above Given List of words using For Loop.
# Inside the Loop, Reverse each word of the list Using Slicing method and
# store it in a variable.
rversd_wrds = [wrd[::-1] for wrd in splt_wrds]
# Join all the reversed words of a given sentence using the built-in join( ) function
# and store it in another variable.
finl_sentnce = " ".join(rversd_wrds)
# Print the reversed Sentence of each word of a given String.
print("The Reverse of each word of the above given sentence = ", finl_sentnce)

Output:

The Reverse of each word of the above given sentence =  olleH siht si skeeghcetb

Method #2: Using split() Method (User Input)

Approach:

  • Give the string as User input using input() function and store it in a variable.
  • Split the words of the given string to a list of words using the built-in split() function and store it in another variable.
  • Traverse in the above-Given List of words using For Loop.
  • Inside the Loop, Reverse each word of the list Using the Slicing method and store it in a variable.
  • Join all the reversed words of a given sentence using the built-in join( ) function and store it in another variable.
  • Print the reversed Sentence of each word of a given String.
  • The Exit of the program.

Below is the implementation:

# Give the string as User input using input() function and store it in a variable.
strng = input(" Enter some random String = ")
# Split the words of the given string to a list of words using the built-in split() function and store it in another variable.
splt_wrds = strng.split()
# Traverse in the above Given List of words using For Loop.
# Inside the Loop, Reverse each word of the list Using Slicing method and
# store it in a variable.
rversd_wrds = [wrd[::-1] for wrd in splt_wrds]
# Join all the reversed words of a given sentence using the built-in join( ) function
# and store it in another variable.
finl_sentnce = " ".join(rversd_wrds)
# Print the reversed Sentence of each word of a given String.
print("The Reverse of each word of the above given sentence = ", finl_sentnce)

Output:

Enter some random String = Good Morning btechGeeks
The Reverse of each word of the above given sentence = dooG gninroM skeeGhcetb
