Install python2.7 on windows 32bit environment
2017/2/14 postscript.
At the time of writing the article, I recommended 2.7 series because the library I want to use may not be compatible with python3 series. Since a considerable number of libraries already support python3, we recommend installing 3 series unless there are special circumstances. In particular, since the handling of character strings is different between python2 series and 3 series, it is safer to use 3 from the beginning than Japanese-speaking people struggling to move from 2 to 3. You can check the compatibility of major python libraries from the following site. https://python3wos.appspot.com/
It is assumed that the 2.7 series and 32-bit version are installed due to the number of libraries that can be used. The procedure itself is the same when installing the 3-series or 64-bit version.

Settings at the time of install.
I think [Add python.exe to Path] is ☓ by default,
If you select [Will be installed on local hard drive], you will not need to go through the PATH later.
When you reach this page, you're done.

If you press the R button while holding down the windows key, the following window will start, so you can also start it by typing cmd and pressing the enter key.
When the command prompt starts, the following screen will appear. Type python in it and press the enter key.
If the installation is successful, you should see the python version number and the > >> input console.
To exit this screen, type ``` >>> quit ()` ``, or press Ctrl-Z and then the enter key to quit python.
Before you start writing a program
Python has a lot of libraries, and you can combine the libraries you want to use. I think we will be creating a new program. It is recommended to install the library after creating a virtual environment instead of installing it directly. The virtual environment is described in here, so please refer to it.
