Override Python's 'in' operator?

Question

Let's assume, I am making my own class in Python, what function should I define in order to permit the utilization of the 'in' operator, for example

class MyClass(object):

    ...

m = MyClass()

if 54 in m:

    ...

Answer 1

Try the following code:

MyClass.__contains__(self, item)

This function helps you to define in order to permit the use of the 'in' operator.
