    3. Scroll down to the files section on the bottom.

    4. Click Windows x86-64 executable installer and save the file. Note: This is the 64-bit
       version, if you need the 32-bit version click Windows x86 executable installer. Nearly
       all recent computers can run 64-bit.

    5. Once it is finished downloading, run the installer.

    6. Make sure you click “Add Python 3.X to PATH”, where X is the latest subversion.
       This make it a lot easier to install Python packages.

2      Installing Packages
Installing packages allows you to use code written by other people. You can install them by
doing the following:

    1. Search cmd or command prompt in the Windows search bar and open it. This is an
       application.

    2. Install Python packages with the following command:

       pip3 install [insert package name(s) here]

       where [insert packages name(s) here] is the name(s) if the package(s) you want
       to install.

       For example, for all the packages you need in CSCI 127 at Hunter College, you would
       want to type:

       pip3 install numpy image matplotlib scipy pandas folium

You have successfully installed Python packages.


3      Troubleshooting
If you see ‘pip3’ is not recognized as an internal or external command, operable
program or batch file, then you likely didn’t add Python to PATH during installation.
Try reinstalling, but make sure you add it to PATH.
