I have a python file but when I attempt to run it on my command line it wants to run it using Python 2.
I have #!/usr/bin/env python3 as the first line of code but it still wants to run it using Python 2. If it helps I'm on OSX.

I was running it as `python filename.py` – card100 Feb 07 '18 at 06:10

1Run `which python3` and then put that path on the shebang line, or just use `python3 filename.py` – cs95 Feb 07 '18 at 06:10

Either,
Use
python3 filename.py, orCreate an alias. Add
alias python=python3in~/.bash_profile, runsource ~/.bash_profile, and thenpython filename.pyshould invoke python3, orRun
which python3, copy the path and add it at the top of your script as the shebang line. For me, the command returns/Library/Frameworks/Python.framework/Versions/3.4/bin/python3. It may be different for you, orYou can also use
pyenv, which supports multiple python environments simultaneously.
