Q & A

What is a module in Python?

A module in Python is a file containing Python code, including functions, classes, and variables, which can be reused across programs.

What are built-in modules in Python?

Built-in modules are those that come pre-installed with Python, providing a range of functionalities without needing additional installations.

What is an executable module?

An executable module is a module designed to be run as a standalone program, typically containing a main function.

What are user-defined modules?

User-defined modules are those created by the user, allowing for the organization of code into separate files for better manageability.

What does 'importing a module' mean?

Importing a module means bringing in the functions and variables defined in that module into the current script for use.

How can you create a user-defined module?

To create a user-defined module, you simply define your functions and variables in a Python file and save it with a .py extension.

What is the purpose of the 'main' thread in Python?

The 'main' thread in Python is the primary thread where execution starts, and it can manage other threads that perform tasks concurrently.

What are external modules in Python?

External modules are those not included with the standard Python distribution and must be installed separately, often from third-party sources.

Can you use functions from built-in modules directly?

Yes, functions from built-in modules can be used directly after importing the module using the 'import' statement.

What are some examples of built-in modules?

Examples of built-in modules include 'math', 'os', and 'sys', which provide various functionalities like mathematical operations and operating system interactions.
