Python version 3.7

That cannot be true, because the syntax error is an f-string, which are available since 3.6. Please double-check that pip3 is running the Python you think it's running.

You are correct. My pip was actually pointing to python3.5.

We should remove this and error out better.

Running in anaconda environment in windows. I am new to python. Not sure what I did wrong.

Your pip3 is for a different Python.

You are right. should I use pip instead of pip3?

Well, your pip probably points to python 2. You should find the pip binary that is related to your python 3.7. Helping you with that is probably beyond the scope of this issue.
