... 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.


In python you might have a nested loop.

for i in range(5):
    for j in range(i):
        print((i, j))

This can also be turned into a comprehensions.

[(i, j) for i in range(5) for j in range(i)]

Even if there are if statements in the loops.

for i in range(5):
    if i > 2:
        for j in range(i):
            if j < 2:
                print((i, j))

You can still turn this into a comprehension.

[(i, j) for i in range(5) if i > 2 for j in range(i) if j < 2]
