In the following Code the function g() is called twice, but why? Is it because in function f() that x=g and than function x() is called but in fact it is g()?
x = 99
def f():
x = g
x()
x = 17
def g():
global x
x = 14
g()
f()

You can also check this by simply adding a print statement as in the following:
x = 99
def f():
x = g
print(x)
x()
x = 17
def g():
global x
x = 14
g()
f()
Output would be: <function g at 0x7f2147265c80> which shows that printing x in line 4 is indeed calling the function g()
