Assignment of global variables in a script.

Dear Sirs.

I found the following sentence in the Python documentation: "The statements executed by the top-level invocation of the interpreter, either read from a script file or interactively, are considered part of a module called __main__<https://docs.python.org/3.11/library/__main__.html#module-__main__>, so they have their own global namespace."

In other words, global assignments of variables placed directly in a module's name space are also "statements executed by the top-level invocation of the interpreter", if the module is executed as a script.

Is it stable at all to assign global variables directly in a module which runs as a script? Speaking practically, I have not observed any problem so far.

Regards,
