What is the difference between a module and a script in Python?

In Python, a module and a script are both components of a program but serve different purposes. Here's a detailed explanation of the differences between modules and scripts: Module: - Definition: A module is a file containing Python code that defines variables, functions, and classes, which can be imported and used in other Python programs. It is a reusable piece of code that provides functionality for specific tasks. - Purpose: Modules are designed to promote code reusability, maintainability, and organization. They allow you to break down your code into smaller, manageable units, making it easier to understand and maintain. - Usage: Modules can be imported in other Python programs using theimport statement. Once imported, you can access the variables, functions, and classes defined in the module and use them within your program. - Structure: Modules consist of Python code encapsulated in a.py file, which can include variable assignments, function and class definitions, and executable code. - Examples: Examples of modules in Python includemath,random,datetime, andos. These modules provide various functions and classes related to mathematical operations, random number generation, date and time manipulation, and operating system interactions, respectively. Script: - Definition: A script, also known as a script file, is a standalone program written in Python that can be executed directly without being imported by other Python programs. It typically contains a sequence of instructions and commands that are executed in a specific order. - Purpose: Scripts are used to perform specific tasks or automate processes. They allow you to execute a series of operations, interact with users, process data, and generate output. - Usage: Scripts are executed directly from the command line or by running the script file. They are often used for tasks such as data processing, file manipulation, system administration, and automation. - Structure: Scripts are typically saved in.py files and consist of a set of instructions, which may include variable assignments, function and class definitions, control flow statements (e.g.,if,for,while), and other code constructs. - Examples: Examples of scripts in Python include data processing scripts, web scraping scripts, automation scripts, and command-line utilities. These scripts are designed to perform specific tasks or automate processes, often taking input, processing it, and generating output. Summary: In summary, a module is a reusable piece of code that provides functionality for specific tasks and can be imported and used in other Python programs. It promotes code reusability, maintainability, and organization. On the other hand, a script is a standalone program written in Python that can be executed directly. It typically contains a sequence of instructions and commands that perform specific tasks or automate processes. Understanding the differences between modules and scripts helps in structuring your code effectively and utilizing the appropriate approach based on your program's needs.
