What is a Module?
- Modules are collections of specific functionalities designed or implemented to be incorporated into a program.
- They typically consist of a collection of functions or other entities.
- Examples of modules include the Python turtle module.
Advantages of modular programming:
- Allows breaking down large programs into manageable parts (modules).
- Facilitates separation of programming tasks among individuals or teams.
- Enables individual development, testing, and integration of modules.
- Eases program modification by containing code within specific modules.
Module Specification
- Every module needs to provide a specification, known as its interface, detailing how it is to be used.
- Programs using a module are referred to as clients of the module.
- A module's specification should be clear and complete to enable effective utilization.
- Specifications are often provided using docstrings, which are string literals enclosed in triple quotes.
- Docstrings describe the purpose and usage of functions or other program elements.
- Complete specifications may include details such as input range inclusivity and error handling.
