Your environment does not support Cyrillic in py files, all other editors open them without problems.

When you try to open the working source code, it generates the error "Charmap codec can't decode byte..." and does not open it. I open it without problems in all other development environments, all the necessary libraries are installed in the python used by your environment.

Another problem, I found code that does not produce this error, but its output displays Exit 0 each time, and does not output anything.

However, I added your development environment to the free software site (link).
