class Counter():

    def __init__(self, count=0):
        self.count = count

    def increment(self):
        self.count += 1

with Counter(count=1) as c:
    assert c.count.get() == 1
    c.increment()
    assert c.count.get() == 2
    try:
        c.decrement()
    except AttributeError as e:
        print(e)  # 'Counter' object has no attribute 'decrement'
    assert c.count.get() == 2
