Feb 9, 2010 · There are two built-in functions that help you identify the type of an object. You can use type() if you need the exact type of an object, and isinstance() to check an object’s type against something. Usually, you want to use isinstance() most of the times since it is very robust and also supports type inheritance.

You can check for type of a variable using __name__ of a type. Ex: >>> a = [1,2,3,4] >>> b = 1 >>> type(a).__name__ 'list' >>> type(a).__name__ == 'list' True >>> type(b).__name__ == 'list' False >>> type(b).__name__ 'int'

Nov 29, 2023 · Python offers several methods for identifying an object's type, with the most basic being the built-in type () function, which provides a quick way to check an object's type. More advanced techniques, such as the isinstance() function, offer the advantage of handling class hierarchies and inheritance.

Jan 10, 2023 · In this tutorial, we'll learn about getting and testing the type of variables by using two different ways, and finally, we'll know the difference between these two ways. 1. Checking Variable Type With Type () built-in function. type () is a python built function that returns the type of objects. now let's get the type of these variables. output.

Dec 31, 2008 · The question is somewhat ambiguous -- I'm not sure what you mean by "view". If you are trying to query the type of a native Python object, @atzz's answer will steer you in the right direction.. However, if you are trying to generate Python objects that have the semantics of primitive C-types, (such as uint32_t, int16_t), use the struct module. You can determine the number of bits in a given C ...

Jul 25, 2022 · Python has a built-in method called type which generally comes in handy while figuring out the type of the variable used in the program in the runtime. The canonical way to check for type in Python is given below: In this example, we are trying to check the data type of each variable, such as x, s, and y using type () function. Output:

Learn the top 3 methods for Python check type of variable, including type(), isinstance(), and custom classes. Understand how to ensure robust, maintainable Python code by validating variable types effectively.

Jul 25, 2024 · It's important to know the type of a variable in Python code to avoid errors, make your code easier to read, and ensure it's robust. Whether you're using type(), isinstance(), or type hints with the typing module, Python gives you various options to check and define types.

Mar 21, 2025 · When we create a variable in Python, we don't explicitly declare its type as in some other programming languages. For example: Here, a is an int, b is a str, and c is a list. The type() function is a built - in function in Python that returns …

Jan 30, 2025 · Type testing in Python allows you to check the type of an object or variable during the execution of your code. This can be crucial for debugging, ensuring the integrity of data passed between functions, and making your code more robust and maintainable. 1. Fundamental Concepts of Python Type Testing.
