    def __init__(self):
        self.data = []
    def my_push(self, x):

    def my_contains(self, x):
        return (self.data.count(x))
    def my_show_all(self):
        return (self.data)

arrStack = My_stack()     
arrStack.my_push(1)
arrStack.my_push(2)
arrStack.my_push(1)
arrStack.my_push(3)
print(arrStack.my_show_all())
arrStack.my_pop()
print(arrStack.my_show_all())
print(arrStack.my_contains(1))

'c'
>>> myStack.pop()
'b'
>>> myStack.pop()
'a'

>>> myStack.pop()
