Reverse words in Python

The "reverse words" problem refers to the task of reversing the order of words in a given string while keeping the order of individual characters within each word intact.

For example, given the input string "Hello World", the desired output would be "World Hello", where the words "Hello" and "World" have been reversed in order.

To solve this problem, an algorithm can be designed to split the input string into individual words and then reverse the order of the resulting list of words. The reversed words can then be joined back together to form the final reversed string.

In Python, you can achieve this by using string manipulation and built-in functions. One approach is to use the split() method to split the string into a list of words, then reverse the order of the list using slicing or the reverse() method. Finally, the reversed words can be joined back into a string using the join() method.

This problem is often encountered in text processing tasks, such as text parsing, natural language processing, and data cleaning. It can be a useful skill when dealing with string manipulation and transformation in various programming scenarios.

Program :

 
def reverse_words(sentence):
# Split the sentence into individual words
words = sentence.split()
Reverse the order of the words -1 means end
reversed_words = words[::-1]
Join the reversed words to form the reversed sentence
reversed_sentence = ’ ‘.join(reversed_words)
return reversed_sentence

 
input_sentence = "Hello, Python"
reversed_sentence = reverse_words(input_sentence)
print(reversed_sentence)

#Output

 
Python Hello,
