Find data type python

The most straightforward way to check if an object is of type list is to use Python's built-in type() function that returns the type of the object passed into it. You can then use the equality operator to compare the resulting type of the object with the list using the expression type(object) == list .

What is type () in Python?

What is type class in Python?

type is a metaclass, of which classes are instances.

In the above case: x is an instance of class Foo . Foo is an instance of the type metaclass.

How do you find the id in Python?

Python id() function returns the “identity” of the object. The identity of an object is an integer, which is guaranteed to be unique and constant for this object during its lifetime. Two objects with non-overlapping lifetimes may have the same id() value.
