How to set alias for python3 on OSX

Question

I'm trying to set an alias for python3 so I can run it with python.

Here's my current .bash_profile

# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH
alias python=“python3”
alias 3=“python3”
alias py=“python3”

When I run python I get -bash: “python3”: command not found.

I can run python3 and it will correctly open py 3.X.X (3.6.1 at time of posting).

There are plenty of half-answers over the years on here & SO, and a few comments mentioning my issue, but hopefully this can be a resource for a complete answer. Or maybe one of you is better at googling than I am and it can be a duplicate question!

Solution

When I run python I get -bash: “python3”: command not found

Why are you using “ and ” (smart quotes) instead of ' (normal single quotes)?

Try the following (corrected) .bash_profile

# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH
alias python='python3'
alias 3='python3'
alias py='python3'

Thanks, I saw your comment and fixed the issue. Marked as correct answer. Stupid case of using open after not seeing results using nano (because I didn't open a new instance)
