Getting started with Black in Python.

You can confirm the effect that black has when you run it on the python files.

This is the contents of the file before we apply black;

list_of_numbers = [
    1,
    2,
    3
]

large_dictionary = {1:2, 3:4, 5:6, 7:8, 9:10, 11:12, 13:14, 15:16, 17:18, 19:20, 21:22, 23:24}

This is the contents after black;

list_of_numbers = [1, 2, 3, 4, 5, 6, 7, 8]

large_dictionary = {
    1: 2,
    3: 4,
    5: 6,
    7: 8,
    9: 10,
    11: 12,
    13: 14,
    15: 16,
    17: 18,
    19: 20,
    21: 22,
    23: 24,
}
