To what the others have said I wish to point out that if x is
reassigned _inside the function_ x's scope is now local inside the
function while x also still has a module scope. Consider:

3.6.8:  x = 10
3.6.8:  def foo():
...     x = 5
...     print("In foo x =", x)
...
3.6.8:  foo()
In foo x = 5
3.6.8:  print("In module scope, x =", x)
In module scope, x = 10
