How to install python 3 on windows and set the path

This is a quick video to show you how to install python 3 on windows and set the path to get it working in the command line.
Watch until the end!!

Installing Python can be tricky on windows if you are new to it.

I'll show you here:
- How to download python 3 and install it
- How to find where python is installed
- How to change the installation location and set the environment path variable so you are able to use it in the command line
- How to reconfigure pip3 to be able to install python modules.

I'll show you also how you can keep previous versions of python you have installed and how you can launch python 3.8 by typing "python3" in the command prompt.

This really helped so much. I got frustrated because I couldn't find the files and you taught me I could access them by changing the view to display hidden files. Then I found it very helpful when you showed how to create the new path with the updated python name (for me was Python39). I can now access python through my command center. Thank you so much!!!:)

Thank You so Much!!! I had both python 3.6 & 3.7 installed and I needed to figure out a way to call both executables through cmd. Great Video!!!

Thank you!!!! This was the confirmation I was looking for. Great video on where to install and how to do it right. I think pip was installing into Appdata default location and I was installing Python in C: which caused issues.

Thank you so much, this was incredibly helpful! I didn't know how to set the path, I had installed Python but couldn't use it in the command prompt!

I wish this video was more highly recommended by the algorithm. I uninstalled python and reinstalled it following your instructions. Finally, my path issues have been solved after struggling with it many times. Thank you.

Years later they haven't fixed this. You have to remove the "Installed for all users" first, then run the installer, and under advanced Options click on "Install for all users" and it changes the install path to C:\Program Files\Python39\ This way you don't have to manually copy things around and then configure pip again.

Is there any reason why you copied the folder in C: ?
