The code if item % 2 == 1: checks whether the variable item is an odd number.

Here's how it works:

• The % operator is the modulus operator, which calculates the remainder of the division of item by 2.
• If item % 2 == 1, it means the remainder is 1, which indicates that item is odd.

Essentially, this condition evaluates to True if item is an odd number and False otherwise.
