Feb 15, 2025 · Learn how to use Python's isinstance() function to check variable types effectively. Perfect for beginners to avoid common type-related errors.

The value of x is: 10 The value of y is: -5 The value of z is: 0 The type of x is: <class 'int'> The type of y is: <class 'int'> The type of z is: <class 'int'> As you can see, the type() function confirms that x, y, and z are all of the int (integer) type. This is a simple yet powerful way to verify the data types of your variables in Python.
