Changing signature and calls of functions using global variables

[edublancas]

Given the following snippet:

x = 1

def add(y):
    return x + y

add(y=10)

add, depends on x to work, however, since the library creates a new exported.py file with the function definitions, they no longer have access to the global variable.

So we need to update the function calls from:

add(y=10)

to:

add(y=10, x=x)

And modify the function's signature to:

def add(x, y):
    return x + y
