August 27, 2020 - X. looping using enumerate: # this one is probably my favorite arr2 = [10, 20, 30, 40, 50, 60] for i, val in enumerate(arr2): print(i, val) This is literally copied and pasted from my notes. Hope it makes sense. Did anyone else think Python loops were weird? Do you loop any of these differently in Python?

In a loop, the break keyword exits the loop immediately, regardless of the iteration number. Once break executes, the program will continue executing from the first line after the loop.

The document provides an overview of various Python loop constructs including for loops, while loops, break, continue, nested loops, and infinite loops. Key points covered include using for loops to iterate over lists, using range() to specify the number of iterations, using break and continue to exit or skip iterations, and nesting loops to access nested list items.

A for loop in Python is used to iterate over the elements of a list and perform an action on each element. The basic syntax of a for loop assigns each element in the list sequentially to a temporary variable.
