Re: Variable scope inside and outside functions - global statement being overridden by assignation unless preceded by reference

So, I would then assume that if I explicitly include a variable name inside the global statement, then even just assigning it a new value should update the variable in the global context, outside the function?

Yes. Note that the "global" namespace is the module in which the function is defined.
     x = 1
     def f(n):
         global x
         x += n
This updates the `x` global variable in the module where `f` was defined.
If you import `f` and use it in another module it will _still_ update `x` in the original module namespace.
