#Windows7 does not come with Python. You can choose to install Python2 or Python3, or you can install them all.

1. Install python2.7 and python3.5

Go directly to the official website https://www.python.org/ to download and install them.

2. The installation is relatively simple, just click on the exe file and continue to the next step (Note: There is a choice whether to add environment variables during installation. If you choose yes, you will not need to add environment variables later)

If not, please add environment variables. Computer properties---->Advanced system settings---->Environment variables--->path in system variables---->Edit and add the path to install python (for example, E:\python;E: \python\script)

3. Modify the python.exe file in the python2.7 installation directory and rename it to python2.exe. (In this way, run python2.7 in the command window and enter python2, run python3.5 and enter python OR python3)
