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...

Example: Python range(stop) foriinrange(5): print(i)# Iterates through the sequence 0, 1, 2, 3, 4 Python range(stop) Parameter:range(stop)generates a sequence from0tostop-1. Explanation for i in range(5):: for:Initiates a loop that iterates through a sequence of numbers. ...
Listing the elements shows that the range has been reversed, with the odd numbers now appearing in descending order. Unfortunately, range_iterator isn’t a full range object, and it doesn’t support many of the features that you’ve learned about lately. For example, you can’t slice it ...
