Welcome to this quiz on Python Variables and Data Types!
Variables and data types are fundamental concepts in Python programming. Variables store different types of values, such as numbers, text, or collections. Python provides various built-in data types, including integers, floats, strings, lists, tuples, dictionaries, and more. Understanding these concepts is essential for writing efficient and error-free Python programs.
This quiz contains 20 questions to test your knowledge, including multiple-choice, true/false, and fill-in-the-blank questions. Let’s see how well you know Python’s variables and data types!
