I'm somewhat new to Python. I have the following python 2 code:
m = [1,1,7,7,0,0,0,0,1,6,6,9,7,9,2]
randomDigs = m[6 - [3][0]: -1]
What is happening inside randomDigs? I get the following output:
[7, 0, 0, 0, 0, 1, 6, 6, 9, 7, 9]

[3][0] is just a complicated way to write 3 (the first element in the list containing 3 as only element). so your code boils down to m[3:-1] which means: create a new list from m starting from the 3rd (note: list indices start at 0) element up to (and excluding) the last element.
this answer explains how list indexing and slicing works in great detail.

Is the 6 not doing anything then? – user220188 Apr 26 '18 at 17:36

2`6 - [3][0] == 6 - 3 == 3`: yes, the `6` is 'doing' something. – hiro protagonist Apr 26 '18 at 17:37
