By default MacOS ships with Python-2.-. But, I guess most of us have long back started to work with Python-3 and it is very irritating to run pytho...

Worked! Thanks!
I'm not saying anyone would want to install Python 3 without brew, but if they did, pip3 gets installed:
$ pip3 --version
pip 19.2.3 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)
$ pip3 install --upgrade pip

yay Irfan!

Please help!
I’m happy to read that the steps worked for you. The subject of the post I responded to was setting up Python 3 to be the default. From what I can tell, that is what you now have. My goal was to show how I did this directly versus using a package manager like Brew, but not everyone is comfortable with this approach. It looks like you are good to go if you want to work in Python 3 by default.
export PATH=/usr/local/opt/python3/libexec/bin:$PATH
This worked for me! THANK YOU! :D
Thank you for sharing. It saved my day.
-ha! good to hear. I receive a message like yours about once per month. seems like a niche crowd we are in, hoping to avoid brew on our mac. it was exactly what I needed also.
Oh god! Thank you so much for your answer, I had tried everything and I was going crazy with that thing, I did the same with Python 3.7 and I finally see:
$ python --version
Python 3.7.8
Great! I'm happy it help you.
Hello Irfan, thanks for the quick tutorial. I have Catalina, and it didn't work for me. I was able to install python using brew, but even if I create the symlink in /usr/local/bin, it seems it is taking the symlink in /usr/bin which points to python2.7.
When I try to change that symlink, I get the message
ln: python: Operation not permittedAny ideas about what can be done?
Hi, sorry for late reply.
What is the output of this command you get?
ls -l /usr/local/bin/python*Output seem like this (Catalina - 10.15.3)

Hey, what is your MacOS version?
thank you for your reply, i have fix my problem.
Awesome, glad that you fixed it.
I'm on MacOS Catalina and it worked. Strange
how did you fixed it please i have the same issue as yours 100%
Try the original answer and then restart your window. If that doesn't work, try it again without the last part and then restart your window:
I already have homebrew and python 3.7.8 installed and when i followed the steps you provided it still had python 2.7.16 instead of 3.7.8 and i followed every step any idea whats wrong? by the way im on the newest macOS because i just got this laptop a few days ago
Good Job, It works for me. Thanks!
I have followed all the steps but python --version gives Python 2.7.16 as output. Please help.

Hi , Dmitry
Could you solve the problem you have above ? I have the same problem and if you managed to solve it pls share me your way ?
Hey try this:

then

That is worked Irfan. Thanks for your help .
i have followed the mentioned steps to upgrade the installed Python version on my laptop, but when i run python --version the old version comes up.
I want to use the latest version 3.8 to use it on IDLE.
tried every command stream in the posts... No luck:
nick2@NWS-Pro-21 ~ % python3 --version
Python 3.8.9
nick2@NWS-Pro-21 ~ % python --version
Python 2.7.18
nick2@NWS-Pro-21 ~ % python -V
Python 2.7.18
python3 --version
Python 3.8.9
this is on macOS Monterrey 12.0.1
i am an oldie 62 ex unix 5.3.1 and a newbie at same time...
This worked for me -- was able to connect to Python 3.9, so thank you for sharing this. I am not sure why Apple still ships with Python 2 (I have the M1 MacBook pro and still had this!) ;-)
Again, thank you!

Below is the output of ls -l /usr/local/bin/python*: however i am still getting Python 3.7.10 as my default and I will like to change that to python3.9
The first 10 lines of ls -l /usr/local/bin/python* is below :

Did you try this:
ln -s -f /usr/local/bin/python3.9 /usr/local/bin/pythonProvided you have installed Python 3.9.
Thank you for the tutorial!
One thing I am not sure about is pip.
For some reason when I use "pip --version" the outcome is this:
pip 21.2.4 from /Library/Python/3.8/site-packages/pip (python 3.8)
and when I use "pip3 --version", the outcome is:
pip 21.2.4 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)
Any ideas on why are they using different python releases? And how to update it.
I fixed this by reinstalling pip with the following the commands:
curl bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
I found your tip extremely useful to solve the following problem I posted on stackoverflow:
I had a simple .py script that used tkinter, which I wanted to use to create a Mac OS app. I did my work using python 3.7 and IDLE. The script worked fine when run in IDLE, but the app I created using py2app and clear documentation at (py2app.readthedocs.io/en/latest/tu...) would not function,
I updated my Mac's python version from 2.7.16 to 3.7 and the app worked like a charm! Thanks--this made my day.

Usage: /usr/local/bin/python [--prefix|--exec-prefix|--includes|--libs|--cflags|--ldflags|--extension-suffix|--help|--abiflags|--configdir|--embed]
Anyone know what's going on?
EDIT: I fixed this. This step: "Change the default python symlink to the version you want to use from above." should be better explained as to what the command should be. I had changed the wrong part of it
Thank you Steven! I have modified the post. Let me know if anything else needs to be changed.

didn't work.
nice try though

Thank you Irfan!!!
Thanks for the details. Unfortunately, it didn't work for me here is the solution worked for me
OS: Mac OS 10.15.3
Commands worked for me
unlink /usr/local/bin/python
ln -s /usr/local/bin/python3.7 /usr/local/bin/python
I am frustrated... Nothing worked for me. Am i doing something wrong? (macOs 10.13.6)

Thank you! I've being looking for a straight forward article to fix symlinks with Apple's lovely handy work.
worked! thanks
Thanks Irfan
How i could easily switch back to 2.7 if needet for one or other old project ?
Tried
pip3 --version
pip 21.3.1 from /Users/nick/Library/Python/3.8/lib/python/site-packages/pip (python 3.8)
pip --version
zsh: command not found: pip
// That worked for me on Big Sur
exec $SHELL -l
which python
/usr/local/bin/python
python --version
I have solved that by installing the script Update Shell Profile.command
in the python file found in Applications.
I'm wondering why the command "which python" still returns usr/local/bin/python (which is in my case python 2), but "python -V" or "python --version" both return Python 3?
Had to also run this:
export PATH=/usr/local/opt/python3/libexec/bin:$PATH
Thanks, all
I changed the 3.7 in —— ln -s -f /usr/local/bin/python3.7 /usr/local/bin/python —— to match the version I installed, 3.9. Worked perfectly! Thank you!!
Glad it helped you Hannah!
This is not working for me either. I'm getting the same result for the python --version: Python2.7.16. I'm out of ideas on how to fix this.
Why python-3.* version is installed on your system?
Thanks. It's working~^^
Worked perfectly for Big Sur :) Thnx (y)
Thank you, mister. Good job)
It worked also for me!! I've tried opensource.com but their tutorial wasn't working for me, I don't know why 🤷🏻♂️
Thank you!!!
Thank you, this worked a treat!
This is awesome, ideally aliasing should also work
alias python='python3'
Ohh my God, I struggled for over 2hours! Thank you!
Worked in Visual Studio integrated terminal as well --- thank you!!!
Thanks for the solution, So easily and clean!!
Awesome, thanks!
Worked like charm on Macbook Pro 2017, 13" MacOS Catalina. Thank you
Thank you so much. I assumed homebrew made that link for me. I guess either it did or it got overwritten. You've solved the problem that I've spent at least an hour on.
this helped me and solved my problem. thank you!
Also, if after it python's version hadnt chaged just reload your device
How would you revert this?
Thanks dude. It worked.
Glad it helped :)
Thank you so so so so so so much!!!!!! I've been trying to fix this for so long!!!!!
Glad it helped you Alex!
Thanks, very simple and useful!
:)
