... comprehensions.

Python has a system that might simplify your code called comprehensions. They allow you to turn your nested for loop into an amazing single line of code. In this series of videos we'll highlight some useful ways to use them.


Understanding how python does unpacking allows you to create many new variants of comprehensions.

arr = [('a', 1), ('b', 2), ('c', 2)]
for idx, (char, i) in enumerate(arr):
    print(idx, char, i)

Understanding this unpacking allows for very expressive one-liners.

[{key: value, 'i': idx} for idx, (key, value) in enumerate(arr)]
