The Ultimate Guide to Python Programming With Python 3.10 - zip_longest() Function

The video tutorial explains the difference between the zip and zip_longest functions in Python. It highlights how zip_longest can be used to iterate over the longest iterable, filling in nonexistent values with a specified fill value, such as None or 0. The tutorial provides examples to demonstrate the usage of zip_longest and how to handle missing data effectively.

What is the default behavior of the zip function in Python?

• It stops at the longest iterable.

• It combines all elements into a single list.

• It stops at the shortest iterable.

• It fills missing values with zeros.

Which module provides the zip_longest function?

• os

• collections

• functools

• itertools

What does the zip_longest function do differently compared to zip?

• It combines elements into a dictionary.

• It sorts the elements before zipping.

• It stops at the shortest iterable.

• It zips based on the longest iterable.

What is the default fill value used by zip_longest for missing elements?

• False

• Empty string

• None

• 0

How can you change the fill value in zip_longest?

• By using a different module

• By passing a fill value argument

• By using a lambda function

• By modifying the zip function
