How to check if mock has any side effects left?

Question

In python, is it possible to check if there are any and how many side effects are remaining?

For example:

mocked_foo = patch.object(Foo, 'method', side_effects=[1, 2, 3])

Answer 1

This reads the number of digits in the variable.

n=int(input(mocked_foo))
count=0
while(n>0):
    count=count+1
    n=n//10
print("The number of side effects left are:",count)
