Iterate over words of a String in Python

In this article, we’ll explore different ways to iterate over the words in a string using Python.

Let's start with an example to iterate over words in a Python string:

Explanation: Split the string into words and loop through each word

Using split() to Separate Words

Python’s split() method allows us to split a string by whitespace and returns a list of words.

['Learning', 'Python', 'is', 'fun']

Explanation: Here, split() divides the string at each whitespace, resulting in a list of words.

Iterating Directly with for Loop

Once the string is split into words, we can iterate over each word using a for loop.

Python
is
fun

Explanation:

• s.split() returns ['Python', 'programming', 'is', 'powerful'].
• The for loop then iterates over this list, printing each word individually.

Using enumerate to Track Index

To keep track of the word position while iterating, we can use enumerate().

Word 1: Learning
Word 2: Python
Word 3: is
Word 4: fun

Explanation: enumerate() provides a counter (index) with each iteration, which helps in keeping track of word positions.

Handling Extra Spaces and Empty Words

Sometimes strings may have extra spaces. split() handles this well.
