How to Effectively Check Object Types in Python?

How to Check for Types in Python

In Python, there are two primary ways to determine the type of an object: isinstance() and type().

isinstance()

The isinstance() function checks if an object is an instance of a given class or its subclasses. For example, to check if an object o is of type str:

<br>if isinstance(o, str):</p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">...

Copy after login

type()

The type() function returns the object's exact type. This allows you to differentiate between subclasses. For instance, to verify that o is strictly of type str, excluding subclasses:

<br>if type(o) is str:</p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">...
Copy after login
Copy after login
