Welcome to our Python Modules and Packages quiz! Python modules and packages are powerful tools for organizing and reusing code in Python projects. Modules are individual Python files containing functions, classes, and variables, while packages are directories of modules with an additional __init__.py file. In this quiz, you’ll test your knowledge of importing modules, working with packages, and understanding module attributes. Let’s get started and deepen our understanding of Python modules and Python Interview Questions.
