isinstance()seems to be the preferred way to check thetypeof a Python variable. It checks if the variable (object) is an instance of the class object being checked against. # Variables of different types i = 1 f = 0.1 s = "Hell" l = [0, 1, 2] d = {0:"Zero", 1:"One"} ...
Determining Python Variable's TypeTo determine the type of a variable, you can simply use either type() or isinstance() methods, both methods are built-in methods of the Python standard library. In this tutorial, we will be learning about these methods, and how can we use these methods ...

determine a variable's type in Python you can use the type() function. The value of some objects can be changed. Objects whose value can be changed are called mutable and objects whose value is unchangeable (once they are created) are called immutable. Here are the details of Python data...
Python provides two main functions: type(): Returns the type of a variable. isinstance(): Checks if a variable belongs to a certain type. a = 5.5 print(type(a)) # Output: <class 'float'> print(isinstance(a, int)) # Output: False print(isinstance(a, float)) # Output: True ...
