How to Install Python Packages on Windows 7

Windows MSI installer

1. Download the Windows MSI installer (either x86 or x64).
2. Run the program.
3. Take note of the path during the installation. For example, C:Python33 if you want to use the command line.
4. If you do not care to use the command line, you can now use the IDLE integrated development environment for Python and consider yourself done.
5. If you want to use the command line, click on Control Panel.
6. Click on System and Security.
7. Click on System.
8. Click on the Advanced system settings link.
9. Click on the Environmental Variables button.
10. Under System Variables, look for the Variable named Path.
11. Select Path and click on the Edit button.
12. At the end of the Variable value, add the value you took note of in step 3 (i.e. C:Python33) preceded by a semicolon (;) which is used to separate the values, so you would add - ;C:Python33.
13. Open your command line and type 'python' - if successful, you should see three greater than symbols at the command prompt (>>>).
14. To exit the Python interpreter, type 'exit()'.
15. That's it!
