Python: list pip packages size

pip_size.sh

pip list | xargs pip show | grep -E 'Location|Name' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null

It'd probably be safer to use one of the other list formats which are intended to be machine-parseable:

pip list --format json | jq -r '.[]|.name' | xargs pip show...

or

pip list --format freeze | cut -d= -f1 | xargs pip show...

---

Personally, I'd just do this as the entire solution, if I was on a system with GNU awk (so a Mac user or Solaris or whatever might need to use gawk instead of awk; I forget if tolower is standard awk or a GNU extension):

pip list --format freeze | cut -d= -f1 | \
  while read P; do du -hs $( pip show $P | awk -v p="$P" '/Location/{print $2"/"tolower(p)}' ); done

That gives this output on a python 3.9 container with pygments installed. It still fails for some eggs, but gets you close.
