Sometimes, you might want to check the datatype of a variable in Python.

You can check the datatype of a variable using Python's built-in type() function by passing the variable as an argument, and then check the result.

The output will be the repr of the class.

How to use the type() Function to Check the Datatype of a Variable in Python

Here's a code example on how to check the datatype of a variable usingusing Python's builtin type():

Check an Integer

length = 30

type(length)

The output will look like this:

<class 'int'>

Check a Float

pie = 3.142

type(pie)

The output will look like this:

<class 'float'>

Check a String

best_color = "RED"

type(best_color)

The output will look like this:

<class 'str'>

Check a Set

vowels = {"a", "e", "i", "o", "u"}

type(vowels)

The output will look like this:

<class 'set'>

Check a List

vowels = ["a", "e", "i", "o", "u"]

type(vowels)

The output will look like this:

<class 'list'>

Check a Tuple

vowels = ("a", "e", "i", "o", "u")

type(vowels)

The output will look like this:

<class 'tuple'>

Check a Dict

vowels = {"a": "A", "e": "E", "i": "I", "o": "O", "u": "U"}

type(vowels)

The output will look like this:

<class 'dict'>

That's a candid example of how you can check the datatype of a variable using Python's built-in type() function.
