Sort authors in a git repository by total contributed lines (I know it's useless)

main.py

import os
import re

output = os.popen('git shortlog -s -n').read()

lines = {}

for line in output.split("\n"):
    if not line:
        continue

    name = line.split("\t")[1]

    CMD = r"""git log --author="%REPLACE" --pretty=tformat: --numstat | gawk '{ add += $1; subs += $2; loc += $1 - $2 } END { printf "added lines: %s removed lines: %s total lines: %s\n", add, subs, loc }' -"""
    CMD = CMD.replace("%REPLACE", name)
    

    out = os.popen(CMD).read().strip()

    match = re.search(r'total lines: (\d+)', out)
    if match:
        total_lines = int(match.group(1))
        lines[(name, out)] = total_lines


sorted_lines = dict(sorted(lines.items(), key=lambda item: item[1], reverse=True))

for  (name, out), total_lines in sorted_lines.items():
    print(f"{name}: {out}")
