Module variables

[IhorNehrutsa]

First, I want to express my gratitude to the author.
Your explanations are clear and their style very benevolent.

And questions:
Are module variables possible, like module constants?
Module constants https://micropython-usermod.readthedocs.io/en/latest/usermods_06.html

In C code module variables can be declared like

// mymodule
const int some_var;

and then in MicroPython

mymodule.some_var = value
print(mymodule.some_var)

Thanks
