I used the find command to find all python files in a folder, and exlude some folder.
find . -type d ( -path ./venv -o -path ./virtualenv -o -path ./lib ) -prune -o -iname '*.py'
It’s give the following output:
... ./tests/test_a.py ./venv
How can I tweak the find command to exclude ./venv in the resultset?

If you don’t specify any actions, find will implicitly use -print for any file that matches your expression. -prune always evaluates as true (in addition to preventing further recursion), which is why ./venv still ends up being printed.
To avoid that, simply add a -print to your other branch:
find . -type d ( -path ./venv -o -path ./virtualenv -o -path ./lib ) -prune
-o -iname '*.py' -print
Now there’s an action, so find no longer prints everything that happens to evaluate as true, and instead only prints the files you’re explicitly looking for.
