What does double == mean in Python?

== is the equality operator. It is used in true/false expressions to check whether one value is equal to another one. For example, (2 + 2) == 5 evaluates to false, since 2 + 2 = 4, and 4 is not equal to 5. The equality operator doens’t set any value, it only checks whether two values are equal.

What is == in Python?

The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. In the vast majority of cases, this means you should use the equality operators == and != , except when you’re comparing to None .

Is Python a command?
