pycodestyle installed via pip3 but not found by bash

I installed pycodestyle via pip3

pip3 install pycodestyle

But then the example goes

pycodestyle --first optparse.py

And my bash doesn't find pycodestyle. I can find the exact path with

pip3 install --upgrade pycodestyle

which returns Requirement already up-to-date: pycodestyle in /home/user2740/.local/lib/python3.6/site-packages and then do

python3 /home/user2740/.local/lib/python3.6/site-packages/pycodestyle.py --first optparse.py

And I guess I could do an alias, but is there a way to have this happen automatically?
