  Since the thread is about "binding": Python can be very 
  explicit when it comes to binding (should you need it).

  main.py

import types

x = 2

def f():
    return x

# prints "2"
print( f() )

g = types.FunctionType( f.__code__, { 'x': 4 } )

# prints "4"
print( g() )

h = types.FunctionType( f.__code__, globals() )

# prints "2"
print( h() )

def a():
    x = 3
    
    # prints "2"
    print( f() )

    # prints "3"
    print( types.FunctionType( f.__code__, locals() )() )

    # prints "2"
    print( types.FunctionType( f.__code__, globals() )() )

a()
