3. Frameworks & Libraries

Frameworks are collections of core software modules that comprise pre-written code that programmers may utilize to address typical programming tasks. Using frameworks, developers may build project-specific functionality without starting from scratch. Frameworks reduce the amount of code that one has to write. Thus making programming more efficient. Understanding these frameworks and libraries is critical to speed development and creating efficient and scalable applications.

1. Web Development: Let us learn about the various Python libraries used for web applications.

   1. Django

   It is a high-level Python web framework helpful for quickly and efficiently constructing web applications. It follows the Model-View-Controller (MVC) architectural pattern, making it simple to create sophisticated web applications with a well-defined structure. You must know its built-in admin interface and powerful object-relational mapper for developing scalable, maintainable online applications that are simple to install and manage.

   2. Flask

   It is a micro web framework to build a simple website. It is much easier to learn than Django. Flask provides a wide range of extensions, which can be used to add features such as authentication, database integration, and more. Flask is also known for its flexibility, allowing developers to create applications in various ways.

   3. FastAPI

   It is a high-performance Python web framework for quickly and efficiently constructing APIs. It is intended to be simple to use and quick to develop, making it a popular choice for developers looking to build robust APIs. FastAPI is a significant addition to any Python developer's toolkit due to its current features and emphasis on performance.

2. Desktop Applications: Now let us look at the various Python libraries used to create desktop applications.

   1. Tkinter

   It is a GUI (Graphical User Interface) toolkit included with Python. Tkinter is an open-source library and it allows you to build desktop GUI applications using Python. To create interactive and user-friendly desktop programs, Python developers must thoroughly understand Tkinter. To develop interactive interfaces, Tkinter provides a variety of widgets such as buttons, labels, menus, and many more.

   2. PyQT

   PyQt is a Python binding of the well-known cross-platform Qt framework, which is used to create graphical user interfaces (GUIs) for desktop and mobile applications. PyQt has several tools and features for developing powerful graphical user interfaces, such as drag and drop, keyboard shortcuts, menus, and dialogues.

3. Data Visualization: It's time to have a look at various Data Visualization libraries offered by Python.

   1. Matplotlib

   Matplotlib offers a wide range of plotting capabilities and assists developers in creating high-quality data representations. Knowing Matplotlib is essential for Python data analysis and visualization activities. It is widely used to create bar charts, line plots, histograms, and other graphs. Matplotlib is a powerful tool in any Python developer's tool set due to its user-friendly syntax and various features.

   2. Seaborn

   Seaborn is based on Matplotlib and offers a higher-level interface for creating beautiful and useful visualizations with less code. In addition, the library supports various visualization types, such as heatmaps, scatterplots, and line plots, and includes features such as color palettes and statistical analysis tools. As a result, Seaborn is extremely effective for studying and displaying large amounts of data.

4. Machine Learning

   1. TensorFlow

   It is the most popular deep learning library developed by Google. It is a computational framework that expresses algorithms that involve numerous Tensor operations.

   2. Scikit-Learn

   A machine learning library for Python, designed to work with numerical libraries such as SciPy & NumPy.

   3. PyTorch

   It can handle dynamic computation graphs on the go. It also provides an easy-to-use API.

4. Python Multithreading

The following topics you need to learn here:

• Starting a thread
• Join
• Thread pool
• Semaphores

5. File Handling in Python

Python is the best programming language to edit, script, and automate whatever is related to the below file formats.

• .txt
• .csv
• .pdf
• .json
• .zip
