Understanding Python Modules

The video tutorial explains the concept of reusing components in programming, specifically through Python modules. It covers the basics of what modules are, how to import and use them, and the difference between built-in and external modules. The tutorial also highlights the importance of understanding licensing agreements and security risks when using external modules. Examples of built-in modules like the math module are provided to illustrate their use in Python programming.

What is the main advantage of using pre-built components in programming?

• It allows programmers to create new components from scratch.

• It helps in solving the same problems repeatedly.

• It enables programmers to assemble components in unique ways.

• It requires programmers to understand the internal workings of each component.

In Python, what is a module?

• A type of variable used in programming.

• A file of code organized into functions.

• A syntax error in the code.

• A built-in function like print or input.

Why do we need to use the import statement in Python?

• To load a module and access its functions.

• To access built-in functions.

• To delete existing modules.

• To create new functions.

What happens if you forget to include the import statement for a module?

• A name error will occur because the functions cannot be found.

• The module functions will be automatically available.

• The module will be imported by default.

• The program will run without any issues.

Which of the following is a built-in Python module?

• TensorFlow

• Pygame

• Pandas

• Math

What must be done to use an external module in Python?

• It must be imported without downloading.

• It must be downloaded and installed.

• It cannot be used in Python.

• It is available by default in Python.

Why is it important to consider licenses when using external modules?

• To avoid legal issues and respect the creator's rights.

• To guarantee the module is secure.

• To ensure the module is free of bugs.

• To make the module run faster.

What is a potential risk of downloading modules from the internet?

• They are guaranteed to work with all Python versions.

• They might contain viruses or security vulnerabilities.

• They automatically update themselves.

• They are always free of bugs.

Which of the following is a trusted module for data analysis?

• Pandas

• Pygame

• TensorFlow

• Math

Why does the Khan Academy IDE not support downloading arbitrary modules?

• To prevent security risks.

• To make programming easier.

• To save memory space.

• To encourage using only built-in functions.
