Master Python: 4 Essential Skills Every Developer Must Master

Translation: How to become a proficient Python programmer

This article compiles summaries of several valuable resources because many talented authors have already written extensive guides on becoming an excellent Python programmer.

The author’s summary focuses on four core topics: functional programming, performance, testing, and coding standards. Absorbing knowledge in these areas will yield substantial benefits for any programmer.

Functional Programming

Imperative programming has become the de‑facto standard, describing state changes with statements. While often effective, it can lead to complexity and may feel less intuitive compared to declarative styles. For those unfamiliar, the following articles provide a clear introduction; once you try functional programming, you may never look back.

Performance

Many discussions criticize scripting languages like Python and Ruby for low performance, yet the real issue often lies in the algorithms programmers choose. The links below explore Python runtime performance details and demonstrate how to write high‑performance applications. When your manager doubts Python’s speed, remind them that YouTube, the world’s second‑largest search engine, is written in Python.

Testing

Testing can be overwhelming in computer science. Some developers embrace TDD (Test‑Driven Development) and its successor BDD (Behavior‑Driven Development), while others dismiss it as a waste of time. If you haven’t started using TDD/BDD, you’re missing out on powerful tools that improve code quality and deepen domain understanding. The following articles offer practical guidance.

Coding Standards

Not all code is created equal. Some code can be read and modified by any competent programmer, while other code is only understandable by its original author for a short time. This often results from lack of testing and poor coding standards. The links below describe a minimal set of conventions that lead to cleaner, more maintainable Python code.
