https://dbader.org/python-tricks ► Write clean & Pythonic code and start using advanced features in your Python code It's easy to get tripped up by Python's "is" and "==" operators for object comparison. In this video I'll explain the difference with a few easy to understand examples. There's a difference in meaning between equal and identical. And this difference is important when you want to understand how Python's is and == comparison operators behave. The == operator compares by checking for equality - the "is" operator, however, compares identities. The difference between them breaks down to down to two short definitions: An is expression evaluates to True if two variables point to the same (identical) object. An == expression evaluates to True if the objects referred to by the variables are equal (have the same contents).
