Presentation Transcript

Slide1

The “is” operatorSlide2

The is operator

Python has “is” and “is not” as operators

Some people confuse them with == and !=

They are not the same!

x is y is True if and only if x and y are

the same object

It is not the same as comparing the

values

of the objects

You can think of it as asking if the addresses of two things are the same (although that is strictly an implementation detail and could

be done differently

in different versions of Python)
