2:50 To find location of Python3 (Issue: python2 runs default)
8:20 Adding paths manually
13:51 Setting up an Alias
17:24 Find out which python (exact) you're running if you have multiple virtual environments using 'sys'
18:45 You've installed a package but not found when importing
19:38 (Pip show command to show package location)
21:42 When the CL and Editor are using different python versions (Sublime Text as example)
25:25 Virtual environments demo and locating its path using 'sys'

If anyone is trying to do this on Mac Catalina, they have switched from using bash shell to ZSH. This means instead of using nano to edit .bash_profile, you should edit .zshrc instead. Everything else should be the same. Only took me 2 hours to figure this out.

Thanks so much for taking the time to make this! Well described and way easier for me to understand than reading!

[saidadiperi]

This video helped me a lot and saved me a lot of hours. Thank you for the author to breaking down the problem and explaining it in detail! Great job

[GabrielPerboni]

Thank you for explaining what things are rather than simply dictating what needs to be done like most videos do. Now I actually know what I'm doing. Appreciated!

[goodcompanycoffee]

I'm so very thankful for this. Your examples are wonderful, and in helping me in diagnosing why my paths are messed up/packages don't import properly. Until now, I've just swept them under the rug.

[phxdnelson]

GREAT video! Helped me solve two different issues I was having! Keep up the great work!

[mau_lopez]

Thanks a lot Corey, after years of struggling with the confusion of PATHs, I finally got it, urrayy!

[blackx]

This is such a great thorough tutorial. You explain everything so well. Thank you so much for your time and effort to help others!

[beaupersoon]

Still the best fucking python youtube teacher on youtube. Anytime someone asks me where to learn python I direct them to you and tell them to watch your whole channel cuz thats what I did years ago. It not only helped me understand whats happening under the hood in python, it helped me understand how programming works in general. Thank you Corey Schafer wherever you are!

[charleswilson]

Thanks so much for this video! I have been taking online classes and working with multiple different projects and vens plus working with jupiter notebook and importing modules using idle from different versions switching from python2 to 3 has been such a nightmare. This video is perfect.

[AjitKumar-fwfs]

[erniea]

Dang Anaconda jacked up my PATH settings! Appreciate this

[davida.]

Very important explanation for all beginners.
Thank you!

[EnglishGeekWahoo]

I have checked the problem of missed packages when importing by the editor for 3 days, it's my bad that I did not check with Corey from the beginning, Corey always nails it very well, I hope you are doing well my friend!

[tiernotall]

You are the man! all my libraries used to be install on python 2.7. You helped a man today!

[Vinod_Kumar]

I watched your video full even though it helped me to solve the weird python version path problem on my linux environment. Thank you for the amazing tutorial, it really helped me.

I struggled with this for a while - the most helpful part was determining the location with sys.executable. Also I was detoured by putting the $PATH in something called .zshenv - but that didn’t work. So I tried it in .zshrc and that worked. I downloaded the Command Line Tools straight from the Apple Developer Site. So some of the paths are different... like I’ve learned so much from this dude. 🤠👍
