Top 4 Python use cases

Python for Software Development

A robust ecosystem, simple syntax, and various frameworks covering scopes like the security & stability of the software make Python the best language for web development. Python is perfect for applying creativity & scripting applications and websites.

  • Django follows the model–template–views architectural pattern and is suitable for big & complex projects requiring much functionality.
  • Flask is a micro web framework and can help create quicker, more flexible, and scalable applications.

Python helps develop different apps & platforms across industries. The FinTech industry prefers Python over other coding languages due to its ability to manage complex mathematical tasks.

Python for Data Analytics

Data Analytics involves collecting, structuring & analyzing data for the users to make informed decisions. It also includes Data Visualization, Machine Learning & Artificial Intelligence. Python is highly beneficial in streamlining complex & massive data sets. Its unique characteristics make it suitable for data analytics. Python libraries & packages for data analytics, like Pandas, NumPy, and SciPy, enable higher scalability & efficiency.

  • Pandas is a flexible, fast & easy to use data analysis and manipulation tool built on top of Python.
  • NumPy is a package that enables scientific computing with Python. It offers comprehensive mathematical functions, linear algebra routines, random number generators, Fourier transforms, and more.
  • SciPy offers fundamental algorithms for scientific computing & data structures that are applicable across domains.

Python has unique libraries explicitly developed for data visualization. They include Matplotlib, Seaborn, Bokeh, and Pandas.

  • Matplotlib supports the creation of animated, interactive & static visualizations.
  • Seaborn based on Matplotlib, provides high-level interfaces for drawing statistical graphics.
  • Bokeh enables the creation of interactive visualizations and graphics ranging from simple plots to complex dashboards with streaming datasets. Additionally, it helps create JavaScript-powered visualizations without coding in JavaScript.

The most popular Python libraries for Machine Learning & Artificial Intelligence include Scikit-Learn & TensorFlow.

  • Scikit-Learn is built on top of matplotlib, NumPy, and SciPy libraries. It provides simple yet efficient tools for predictive data analysis.
  • TensorFlow helps prepare data, build & deploy ML models, and implement MLOps for ML and AI projects

Further, Python even supports the development of solutions for predictive analysis, risk assessment, sentiment analysis, prescriptive analysis, diagnostics, and more. While businesses across sectors use data analytics, listed below are some examples:

  • It helps the e-commerce & banking industries detect fraudulent transactions.
  • The healthcare sector utilizes data analytics to detect diseases before their symptoms appear.
  • Logistics companies optimize vehicle routes using data analytics.

Its other use cases include inventory management, sales & marketing, smart cities, and more.

Python for IoT Development

Supports programming IoT devices and developing their software backends. It has become essential for IoT thanks to the speed of development & the numerous external & IoT libraries supporting it. Some notable libraries for IoT include; NumPy, Matplotlib, Pandas, TensorFlow and more. Python’s design implements business logic straight at the device level, making it connect with hardware devices easily. It helps build high-performance IoT systems by combining modern frameworks and protocols for data transfer. Python is ideal for developing device prototypes. Even if you do not create the IoT project from scratch, it helps interact with sensors, actuators & accessories.

Here are the three critical approaches for IoT development using Python:

  • Python on Raspberry Pi: Raspberry Pi is a single-board portable computer that can be used for multiple purposes like running different OS, games, web servers, and designing various projects. Developers use Python for Raspberry Pi since it is helpful for interfacing Raspberry Pi modules when coding is required.
  • Python on PyBoard: PyBoard is an electronics development board that runs MicroPython, a lightweight implementation of the standard Cpython interpreter. MicroPython runs on microcontrollers in constrained environments and uses minimal RAM. PyBoard connects to computers with Windows, Mac, and Linux via USB. It provides a USB flash drive to save Python scripts & a serial Python prompt for instant programming.
  • Micropython with microcontrollers ESP8266 & ESP32: Micropython can run on WiFi microchip – ESP8266 or ESP32. They help create a low-power consumption IoT device that can integrate with wireless WiFi networks. IoT development requires installing Micropython on the computer, utilizing a suitable IDE (integrated development environment) & storing the compiled result in the memory of an ESP8266 or ESP32 microcontroller. Further, it requires writing necessary functionalities on the client side & running the IoT development on the microcontroller.

Python for Legacy App Modernization

Legacy apps need modernization to add ML & data analytics capabilities. And, Python is the most suitable language for app modernization due to its wide application in analytics vertical. With the increasing utilization of ML algorithms across industries, from finance to healthcare, the demand for legacy app modernization & upgradation with Python is increasing rapidly. It would include migrating apps from other technologies like ASP.NET, PHP, Java, etc., to Python.
