3 Ways to Explore a Python Object

When we get a reference of a Python object, how can we know the information about it? Of course, we can read its source code. However, sometimes we don’t have enough time to read it or even we just get this object from an API and cannot access its source code.

This post will introduce three ways to have a quick check of a Python object.

First of all, when we get an object, we can check which type it belongs to by type() method.

Since the type() method returns an object’s type, it can be used to compared two types.

Note: In the above example, we compared type(b)==int and got a True. If we compare type(b)==type(int), a False will be printed. Because the type of int is type.

With the help of the types module, we can check more complex types:

For inherited classes, using the isinstance() method is a very convenient way to check their inheritance relationship.
