# Python: Reverse all the words which have even length

## Python Basic - 1: Exercise-113 with Solution

Write a Python program to reverse all words of odd lengths.

Sample Solution:

Python Code:

``````# Define a function named reverse_even that reverses the even-length words in a given text.
def reverse_even(txt):
# Use a list comprehension to iterate over words in the text.
# Reverse even-length words while leaving odd-length words unchanged.
reversed_words = [i[::-1] if not len(i) % 2 else i for i in txt.split()]

# Join the modified words into a single string separated by spaces.
return ' '.join(reversed_words)

# Test the function with different text inputs and print the results.

# Test case 1
print(reverse_even("The quick brown fox jumps over the lazy dog"))

# Test case 2
print(reverse_even("Python Exercises"))
``````

Sample Output:

```The quick brown fox jumps revo the yzal dog
nohtyP Exercises
```

Explanation:

Here is a breakdown of the above Python code:

• Function definition:
• The code defines a function named "reverse_even()" that reverses the even-length words in a given text.
• Word reversal:
• A list comprehension is used to iterate over words in the text.
• For each word, it checks if the length is even (len(i) % 2 == 0). If so, it reverses the word; otherwise, it leaves it unchanged.
• Joining Modified Words:
• The modified words are joined into a single string using ' '.join(...).
