Here we will discuss the highest level program organization unit, which helps programmers to pack and organize program code and data for reusable purposes. A module provides a simple way to organize program components into a system; grouping similar forms of code into a module makes code easier to understand. It is also referred to as a program object that binds data and can be used as a reference. In other words, it is a file that contains a Python program. Programmers use the 'import' statement to get access to the names in a module's global scope.

Learn Python practically and Get Certified. A package is a container that contains various functions to perform specific tasks. For example, the math package includes the sqrt function to perform the square root of a number. While working on big projects, we have to deal with a large amount of code, and writing everything together in the same file will make our code look messy. Instead, we can separate our code into multiple files by keeping the related code together in packages. Now, we can use the package whenever we need it in our projects. This way we can also reuse our code. Suppose we are developing a game. One possible organization of packages and modules could be as shown in the figure below. This file can be left empty but we generally place the initialization code for that package in this file. For example, if we want to import the start module in the above example, it can be done as follows:. Another way of importing just the required function or class or variable from a module within a package would be as follows:. Although easier, this method is not recommended. Using the full namespace avoids confusion and prevents two same identifier names from colliding. While importing packages, Python looks in the list of directories defined in sys.

Exercise: Insert the missing part of the code below to output "Hello World".

We usually organize our files in different folders and subfolders based on some criteria, so that they can be managed easily and efficiently. For example, we keep all our games in a Games folder and we can even subcategorize according to the genre of the game or something like that. The same analogy is followed by the packages in Python. Python Packages are a way to organize and structure your Python code into reusable components. Think of it like a folder that contains related Python files modules that work together to provide certain functionality. Packages help keep your code organized, make it easier to manage and maintain, and allow you to share your code with others. Creating packages in Python allows you to organize your code into reusable and manageable modules. From performing statistical analysis and visualizing data to delving into advanced topics like deep learning, natural language processing NLP , generative AI, and computer vision, these packages offer a comprehensive toolkit for tackling diverse challenges in the field. From data manipulation to machine learning and visualization, these tools offer powerful capabilities for analyzing data effectively. From basic image processing to advanced object detection, these libraries empower you to tackle diverse computer vision tasks with ease.
