How to make a variable's late binding crosses the module boundary?

[Schachner, Joseph (US)]

The way we do this, is in main.py, call a "globalizer" function in each other file:

    # call globalizers to get shortcuts as global variables
    funcs.globalizer(interface, variable_dict)
    util.globalizer(interface, variable_dict)
    sd.globalizer(interface, variable_dict)
    tests.globalizer(interface, variable_dict)
    ut.globalizer(interface, variable_dict)

Obviously, you may not need a shared interface in which case you can just pass the variable dictionary.

In each file, you have a function:
def globalizer(interface, variables_dict):
    # create global variables for this .py file for shared interface and the variables
    ....

This works well, making sure separate python files shared exactly the same things we want to be global.

  In CPython one then can also:

print( f.__globals__[ "CONSTANT" ])
import sys
module = sys.modules[ f.__globals__[ "__name__" ]] print( module.CONSTANT ) CONSTANT = module.CONSTANT print( CONSTANT )
