1# pprint (aka prettyprint) is a function that allow to print objects in a clearer way
2# Fist you need to import the pprint module
3import pprint
4# then you can create a printer whith whatever arguments you need
5my_printer = pprint.PrettyPrinter(width=20)
6# default arguments are : indent=1, width=80, depth=None, stream=None, *, compact=False, sort_dicts=True
7
8# let's take this list as an exemple:
9list1 = [[0,1,2,3,4],[1,2,3,4,5],[2,3,4,5,6],[3,4,5,6,7]]
10
11print(list1) # will print [[0,1,2,3,4],[1,2,3,4,5],[2,3,4,5,6],[3,4,5,6,7]]
12my_printer.pprint(list1) # will print:
13# [[0, 1, 2, 3, 4],
14#  [1, 2, 3, 4, 5],
15#  [2, 3, 4, 5, 6],
16#  [3, 4, 5, 6, 7]]
17
18# You can also formant text whith pprint
19output = my_printer.pformat(list1)
20# output will be:
21"""[[0, 1, 2, 3, 4],
22 [1, 2, 3, 4, 5],
23 [2, 3, 4, 5, 6],
24 [3, 4, 5, 6, 7]]"""
