Global Variables

Post by Nikunj_Vadher » Tue Dec 18, 2018 9:27 am

How to declare global variables in micropython that can be accessible from boot.py, main.py and many files.
creating and writing and updating file data taking time and getting into error.I want to declare only 2 variables.
Also want to create and freeze(compile) code for python server that listen on port for request.

Thank You.

That's not possible in python, only in lua.
If you want to have accessible globals you have to declare those in a module e.g. "config.py" and then import that module in every other file/module that wants to access these.

Depending on your variable you can do as @stijn suggested in this post.

If you create a variable in boot.py it will be available to main.py and to the REPL. But it won't be available to modules you import because of the way Python namespaces work: you would need explicitly to pass it to functions/methods in the module.
