globals()
When I meet the case when I have to have a dictionary of mutable global variables, I always implement it this way:
global_vars = {}
global global_vars
def some_function():
global_vars['foo'] = 'bar'
When I write it like this, my IDE always suggests some annoying function called globals() - what in the world is that??
And apparently I learned it soon - it is a built-in “global_vars”, a dict with everything I need from global_vars.
There is actually no need to create a global dictionary by my own, Python already does that for me.
I can use it like this:
def some_function():
globals()['foo'] = 'bar'
Better start using it soon!
