Congratulations
you have just proven that you have faild in your understanimg of python @
stage 1 becuae you keep tying to us it a C
try the following
def test(x):
print (id(x)
a=100
print (id(a))
test(a)
a="Oops i was an idiot"
print (id(a))
test(a)
python always passes the object bound to a, not the value of a or a
pointer to a
