Python - Reversed Split Strings

Last Updated : 18 Jan, 2025

In Python, there are times where we need to split a given string into individual words and reverse the order of these words while preserving the order of characters within each word.
For example, given the input string "learn python with gfg", the desired output would be "gfg with python learn". Let's explore a few ways to achieve this efficiently in Python.

Using split() and reverse

This method involves breaking the string into a list of words using the split() function and then reversing the list in place using the reverse() method.

Python

s = "learn python with gfg"  # Break the string into words and reverse the list words = s.split()  # Split into words words.reverse()  # Reverse the list in place print(words)

Output

['gfg', 'with', 'python', 'learn']

Explanation:

The split() function divides the string into a list of words based on spaces.
The reverse() method changes the order of the elements in the list to reverse.

Let's explore some more methods and see how we can split a string into a list of words and then reverse the order.

Using split() with slicing

This approach uses slicing to reverse the list after breaking the string into words.

Python

s = "learn python with gfg"  # Break the string into words and reverse the list using slicing words = s.split()[::-1]  # Reverse the list using slicing  print(words)

Output

['gfg', 'with', 'python', 'learn']

Explanation:

split() function divides the string into words.
Slicing with [::-1] creates a new list with elements in reverse order.

Using for loop

This method manually iterates over the string using a for loop, breaks it into words, and constructs the reversed list.

Python

s = "learn python with gfg"  # Initialize an empty list for reversed words words = []  # Break the string into words and iterate in reverse order for word in s.split()[::-1]:     words.append(word)  # Append each word to the list print(words)

Output

['gfg', 'with', 'python', 'learn']

Explanation:

split() function divides the string into words.
The list is reversed using slicing, and words are added to a new list using a for loop.

Using list comprehension

This approach combines breaking, reversing, and collecting words in a list using a concise one-liner list comprehension.

Python

s = "learn python with gfg"  # Reverse the list using list comprehension words = [word for word in s.split()[::-1]] print(words)

Output

['gfg', 'with', 'python', 'learn']

Explanation:

split() function divides the string into words.
Reversing is done using slicing with [::-1], and words are added to a new list with list comprehension.

Using reversed()

This method simply uses the reversed() function to reverse the list of words.

Python

s = "learn python with gfg"  # Break the string into words and reverse using reversed words = list(reversed(s.split()))  # Convert the reversed iterator to a list print(words)

Output

['gfg', 'with', 'python', 'learn']

Explanation:

split() function creates a list of words.
reversed() function creates a reversed iterator which is converted to a list.

Reverse Sort a String - Python

The goal is to take a given string and arrange its characters in descending order based on their Unicode values. For example, in the string "geeksforgeeks", the characters will be sorted from highest to lowest, resulting in a new string like "ssrokkggfeeeee". Let's understand different methods to pe

Python - Reverse Slicing of given string

Reverse slicing in Python is a way to access string elements in reverse order using negative steps. Using Slicing ([::-1])Using slicing with [::-1] in Python, we can reverse a string or list. This technique works by specifying a step of -1, which starts at the end of the sequence and moves backward,

String splitting, including spaces refers to breaking a string into parts while keeping spaces as separate elements in the result. Using regular expressions (Most Efficient)re.split() function allows us to split a string based on a custom pattern. We can use it to split the string while capturing th

Reverse All Strings in String List in Python

We are given a list of strings and our task is to reverse each string in the list while keeping the order of the list itself unchanged. For example, if we have a list like this: ['gfg', 'is', 'best'] then the output will be ['gfg', 'si', 'tseb']. Using For LoopWe can use a for loop to iterate over t
