Python33 and Python27

Question

Python

In general, it was Python33, I wrote an application in the GUI and decided to make an exe, after searching the internet I realized that I needed Python27, downloaded it + libraries, now there are problems:
1) You can’t just run the script on the desktop, you need to write c: \ pythonXX in cmd the address of the script . How to make 33 by default? in Path specified everything.
2) Encoding when using 27, although I wrote at the beginning # -*- coding: utf-8 -*- still does not work, does not accept Russian even in comments. How to fix it? Version 27 is only needed to make an exe with py2exe.

Answer 1

I can be wrong, but in my opinion this tool allows you to build exe for the 3rd python

Answer 2

The python that you consider not the main one needs to be renamed, i.e. in the python 2.7 folder, rename python.exe to python27.exe. Then version 3 will be called by default, and you will need to specify the path for this specifically. I didn’t use it myself, I read it somewhere in Google because I myself have such a zoo. There is a simpler winpython method and some other assemblies are provided in a portable way, which is the way I went. On the second point, I'm afraid in no way, utf appeared in python only from the third version.
