Sure but if you reassign the variable that was passed it, it has no
effect whatsoever on the caller's variable, mutable or not. This is why
people argue for "pass by value." Because of this confusion, we often
say, "pass by object."
For example
def foo(bar):
bar.append(5)
bar = 6 #bar is no longer referring to a list
a=[1,2,3,4]
foo(a)
print (a)
# prints [1,2,3,4,5]
