works just fine with Python 3.6

there is a slight version mismatch between botostubs and boto3, so I've created a fresh virtual environment and installed the versions to match via pip install boto3==1.14.38 botostubs==0.12.1.14.38

Thanks for letting me know, Alex.
My mistake was to enforce python>=3.5 . It should be python>=3.6 instead for PEP 526

We could always make the code compatible with older versions but I don't have time to look into it. Would you like to contribute?

Else, see if the boto3-stubs project works better for you.

P.S: botostubs and boto3 versions do not strictly have to match.

thank you, I'm ok with using 3.6 in dev. botostubs works better for me as it requires less code change, compared to boto3-stubs. Also it works without mypy and doesn't have a dependency on any other plugin in PyCharm.
