S Sep 3 at 15:45	history	suggested	wjandrea	CC BY-SA 4.0	Add a header for each solution. Clarify: `-b` won't "have" non-printable characters raw, but escape them. Use Python 3 print syntax, which is also valid in Python 2.
Sep 3 at 13:28	comment	added	wjandrea		I submitted a suggestion to have `os.walk()` default to the current dir :)
Sep 3 at 13:04	comment	added	wjandrea		oops, `os.walk()` requires an argument. Still, `os.listdir()` doesn't.
Sep 3 at 13:02	comment	added	wjandrea		Don't build a list just to get its `len`; use `sum` instead. Also, you can use unpacking instead of indexing into `i`. So: `python -c 'import os; print(sum(len(d+f) for (_p, d, f) in os.walk(".")))'`

Sep 3 at 12:56	comment	added	wjandrea		`os.sep`??? That's `/`, i.e. the root dir. Did you mean `"."`, for the current directory? You can actually remove the argument entirely (`os.listdir()`) and it'll automatically use the current dir.
