Solid knowledge of the Python programming language: A deep and clear understanding of Python syntax, OOP principles, data structures (tuples, dictionaries, lists), and functional programming paradigms is necessary. Also, they should be proficient in exception handling, code optimization, and debugging.
Understanding of Python frameworks: Python developers should have expertise in at least one Python framework – Pyramid, Flask, or Django to build feature-rich and bespoke web apps. They should also excel in database interactions, templating, middleware components, and routing. RESTful API dev is preferred.
Proficiency in ORM (Object Relation Mapper): Python developers should have a strong command of ORMs such as Django ORM and SQLAlchemy for superior data manipulation, modeling, and querying. They must also possess knowledge of database schemas, performance optimization tactics, and database relationships. They should be able to write complex database queries.
Excelling at Python libraries: Comprehensive knowledge of core libraries such as Pandas, NumPy, and Matplotlib is essential for data visualization and analysis. Also, Python developers must also possess proficiency in special libraries like PyTorch, TensorFlow, and Scikit-learn for machine learning tasks.
Machine learning and AI: The latest kids in the market, AI and ML are growing fast. A strong foundation of ML algorithms, training, model development, and evolution is not essential but a must these days. Python developers for hire should also have deep learning architecture proficiency along with NLP and computer vision.
Understanding of multi-process architecture: In-depth knowledge of the processes management and inter process communication (IPC) mechanisms is sought after as a good skill. Parallel and distributed computing paradigms and the ability to design and implement multi-process theories are also recommended.
Version control: The Python developers on the floor should also possess expert-level proficiency in Git for better code management and collaboration along with branching strategies. They should be able to merge and conflict resolution in order to understand distributed version control systems.
CSS, HTML, and JavaSrcipt: A strong hold on front-end technologies to create interactive user interfaces for the best UX as well as knowledge of responsive design, JavaScript libraries like React, Vue, and Angular along with CSS framework expertise is indeed quite helpful to Python developers.
