Answer: You can use the built-in type() method to determine Python variables.
We generally get to know about the type of variable just by the value it got assigned, whereas in some cases we want to check about the type of variable. This can be done by using the Python built-in functions and modules which are discussed below:

Methods to Determine Data Type of Python Variables
The following are some of the most common methods that are used to determine the variable type in Python:
Method 1: Using type() Function to Determine Variables in Python
When you are working with a variable and you want to know about the type of data you are dealing with, the type() function can provide you with the type of data. It is also used in the debugging process because, in Python, variables are not declared with the data type they belong to.
Example:
Output:
Method 2: Using isinstance() Function to Determine Variable Type in Python
It is a built-in function with more flexible operations. This function contains two arguments. If the first argument is an instance of the class of the second argument, accordingly the boolean value gets printed.
Example:
Output:
Method 3: Using typing module in Python
It is the advanced method of determining the data type. You can use a typing module when you are assigned with large codebase and you need to know about its type.
Example:
Output:
Method 4: Using __class__ attribute to Determine Variable Type in Python
Unlike type() function, __class__attribute is special as it doesn’t require a function call. This attribute can directly give the variable class.
Example:
Output:
Method 5: Using type Hinting with the Variables in Python
It gives a hint about the type of data and the function returns the value. This method helps the developer to understand easily.
Example:
Output:
Conclusion
Knowing the datatype is more important when dealing with a larger codebase. The type of data can be identified by the methods discussed above. And these are flexible approaches to get to know about the datatypes.
