Examples to Check Data Type in Python Let us discuss certain ways through which we can print the datatype of the variable. 1. Using type(object) Method to Check Data Type in Python In this example, we will be t
Using thetype()function to check for type in Python is considered the most canonical approach.Thetype()function is specially designed to check for the type of an object. It returns the name of the type that the object belongs to. However there are more ways, let’s see them. Some people...
