How to Install and Properly Set Up Python 3 - macOS Mojave or Older

In this video, I walk you through the process of installing Python 3 and properly setting it up so that it becomes the default instead of the System Python 2.

I had so much stress trying to figure out how to do this on my own, I called my dad but he doesn't fully know how to do it step by step, but the plan he does know. Thank you for making this video, again, it really helped me. Now I somehow have the latest version of Python and Pip which is amazing. Thank You!

This will be an amazing video to send to whoever wants to start with python on Mojave, plus there's a Catalina version!

Hi.
I want to learn coading so I tried following your steps on how to install python on Mac Os Mojave but I got lost on minute 9:52 after entering command install python am getting a different message to yours...

Warning: A newer command line tools release is available update them from from software update in system preferences.

Well I dont know how to go on from there


It says if the update from system preferences doesn't work to run:
sudo rm -rf
sudo xcode-select --install




Or manually download the command line for new updates

Hi, thank you so much for this video. I'm having some problems installing Homebrew in a MBA 2010 (El Capitan). I already tried uninstalling an re-stalling because it always stops at

./bootstrap --no-system-libs --paral
make

could you help me out? I would appreciate the help. Thanks again. I'll let it run all night and update this comment if it advances.

thank you very much, this is a very good and informative video. but what i think many people need after this is guidance on how to use what we have just done/installed. I did everything you did in the video. i have the python3.9 version running. but which script editor do i use? where can i get the console when i dont have a script editor? how do i start writing programs in python now that ive followed your video?

is the installation via the terminal (like yours) equivalent to installing python 3.9 by downloading from the website?

how do i start if ive watched this video till the end?

thank you very much,
best wishes

Thank you for the video! I couldn't install homebrew with the one line code because my macOS is X El Capitan 10.11, and according to the documentation on homebrew's website, it requires at least mojave 10.14 or newer. Is there any way to find the one line code that works for my system? Or if there's any other way to fix it please kindly point me some directions! Thanks!

I'm almost done. When I write python it shows the new version. But when I write ls -a it says : "-bash: ls: command not found" Would that be a problem??

After I follow this tutorial why my python version still 2.7 on terminal? But in Applications folder there is python 3.8 and python 3.9, I don't see python 2.7.
And how to make latest version python as default?

Copied and pasted the Homebrew script into Terminal and got "Illegal variable name."

Thank you! This works wonderfully to upgrade my Python 2.7.10 to Python 3.9! But I have a question, this doesn't come with the pip3. My version says pip 21.0
Can you make a tutorial video on how to install pip3 for Mojave?
