What is a module in programming?

A module in programming is indeed a file containing Python code. Modules are a way to organize and structure code in Python, allowing developers to break down complex functionalities into manageable segments. This facilitates code reuse and improves maintainability. By encapsulating code in modules, you can import and utilize functions, classes, and variables defined in one module in other modules or scripts. This modular approach promotes better organization, enhances readability, and helps avoid code duplication.

Other options, while related to programming, do not accurately define a module. A graphical interface for coding refers to environments that aid coding visually but doesn't define a module's function. A type of programming language suggests a categorization that doesn't pertain to the concept of a module. A method for debugging code implies a process for identifying errors, which is different from the structural role of a module in programming.
