The reason why Python is extensively used and considered one of the top-used programming languages in 2024 is its ease of use, clean and readable syntax, extensive 3rd party integration capabilities, and wide range of free libraries.

In fact, the design philosophy of the Python programming language focuses on code readability through exclusive use of whitespace. On the flip side, its object-oriented approach helps developers write clean and logical codes for small, medium, and large projects.

This has made the Python programming language a staple in data science and machine learning allowing developers to use the language to create data visualization, statistical calculations, manipulate and analyze data, build foundational models, and more.

Additionally, Gen AI led the rise in its adoption and scaling, which highly earned the business value for the takes, shapers, and makers who used the AI and Machine Learning models customized with proprietary data or built from scratch.

Even if you haven’t worked closely with ML models, this blog is a detailed guide that will save your time in exploring and selecting the best Python libraries for Machine Learning projects. It also covers answers to why decision makers like you choose Python as backend technology over others.

Once users add the details, the platform generates AWS infrastructure in the backend for the user, based on their requirements. We have used Cloud Formation, RDS, Lambda, EC2, SQS, S3 from AWS and Boto3 to access AWS via Python code.
  • An app that controls product reviews with automated discovery of negative /positive reviews through the use of Python libraries like SKLearn, TF-IDF, Pandas, NumPy, Django, and Django Rest Framework (DRF).
  • By using the Azure AI, Django, and Django Rest Framework, we generated an OCR model that fetched data from the parking fines receipts.
  • Built a solution where users can upload their documents like PDF, Doc file, and other formats. The ML models fine-tune the text inside the document and users can ask questions that the model answers based on the fine-tuned text. We have used FastAPI, Transformers, Watchdog, Cryptography, LlamaIndex, Gradio, PyTorch, and Sentence-Transformers for this project.
