Python’s built-inenumeratefunction allows us to loop over a list and retrieve both the index and the value of each item in the list: presidents=["Washington","Adams","Jefferson","Madison","Monroe","Adams","Jackson"]fornum,nameinenumerate(presidents,start=1):print("President {}: {}"....
In Python, theforloop is a versatile tool for iterating over sequences of items. By using theenumerate()function, you can easily retrieve the index of each item during iteration. This allows you to access both the index and the item itself, making your code more efficient and readable. ...
Python for Loops: The Pythonic Way In this quiz, you'll test your understanding of Python's for loop. You'll revisit how to iterate over items in a data collection, how to use range() for a predefined number of iterations, and how to use enumerate() for index-based iteration.Getting...
