Python what type is variable

If the object is the only parameter passed to type then it will return you the type of the object. If the params passed to type is a type object, bases, dict , in such case, it will return a new type of object. In this, example we have a string value, number , float value, a complex number, list, tuple , dict and set. We will use the variables with type to see the output for each of them.

When you check the object created from a class using type , it returns the class type along with the name of the class. In this example, we will create a class and check the object type created from the class test.

The three parameters passed to type i. The name represents the class name, the bases is the base class, and dict is the dictionary of base class attributes. In this example, we are going to make use of all three params i. When you pass all three arguments to type , it helps you to initialize new class with base class attributes. Python isinstance is part of python built-in functions. Python has various standard data types that are used to define the operations possible on them and the storage method for each of them.

Number data types store numeric values. Number objects are created when you assign a value to them. You can also delete the reference to a number object by using the del statement. You can delete a single object or multiple objects by using the del statement.

Python allows you to use a lowercase l with long, but it is recommended that you use only an uppercase L to avoid confusion with the number 1. Python displays long integers with an uppercase L. Strings in Python are identified as a contiguous set of characters represented in the quotation marks. Python allows for either pairs of single or double quotes. Subsets of strings can be taken using the slice operator [ ] and [:] with indexes starting at 0 in the beginning of the string and working their way from -1 at the end.

Lists are the most versatile of Python's compound data types. A list contains items separated by commas and enclosed within square brackets []. This tutorial will go over a few basic types of variables. Numbers Python supports two types of numbers - integers whole numbers and floating point numbers decimals.

Hello, World! Multiple Function Arguments. Read our Terms of Use and Privacy Policy. Variables and Their Types in Python A variable is nothing but a box or container inside which our data will be stored. Number: This category contains integers, floating-point numbers, and complex numbers.

String: It is a sequence of Unicode characters. A Unicode is a character set that contains characters and symbols from all languages around the world.

Boolean: Boolean represents either True or False. List: It is an ordered collection of elements of the different data types. Lists are mutable, which means values inside the list can be changed after it has been created.
