How can i open pip file codes to read?

I’m trying to check how the (pip black) is written and would love to read its code but having trouble.

I downloaded the file from browser but its on gz format and when I try to open it on VSCode I get cryptic lines like

���nc�Onlyfinnaly.log

What am i supposed to do?

I tried downloading the pip directly on VSCode and checking the commands avaliable also opening it on text editor but its no help. I was expecting to be able to read the lines of codes that are written on the pip file
