Python Has Serious Problems, But I Use It Anyway

Python Has Serious Problems, But I Use It Anyway

A personal, non-technical reflection on why the presenter once disliked Python, which of those complaints remain valid, and why they nevertheless choose Python for most of their work. This is not a tutorial and contains no code examples — it focuses on trade-offs, mindset, and practical usage.

Main theme

The presenter outlines a pragmatic stance: Python has real flaws that matter in certain contexts, but its strengths (ease of use, ecosystem, and productivity) make it the right tool for many tasks. The piece emphasizes trade-offs rather than dogma.

Key technical criticisms

• Whitespace/indentation defines scope Feels fragile compared to brace-delimited languages; leads to occasional annoyances and surprises.

• Dynamic typing / lack of strictness Many errors only surface at runtime. Type hints are optional and not enforced by the interpreter.

• Type annotation ergonomics Callable type hints and generics (especially before Python 3.12) are verbose and difficult to read.

• Class design oddities Use of init and explicit self, confusion between class vs. instance variables, and quirks with dataclasses.

• Imports and packaging pain Relative vs. absolute imports, ambiguity about when a folder counts as a package, and inconsistent behavior across contexts.

• Dependency management fragmentation Historically messy: venv, pip, requirements.txt, poetry, pipenv — though the ecosystem has improved.

• Performance limitations Generally slower than compiled languages (C++, Rust, Go); this can be a real concern depending on the domain.

Why the presenter still uses Python

• Extremely easy to set up — great for quick scripts, tooling, and automation.
• Massive ecosystem and integrations, especially dominant in AI/ML and LLM tooling.
• Excellent for “glue code” (orchestration, API integrations, payments/emails/LLM APIs, DB interactions) where network or DB latency is usually the bottleneck.
• Large corpus of existing code means strong support from AI coding agents and third‑party libraries.
• Practical trade-offs: productivity and ecosystem advantages often outweigh the language’s flaws for the presenter’s typical use cases.

Broader lessons and advice

• Don’t tie identity to a single language — tribalism prevents objective trade-off analysis.
• Choose languages and tools based on outcomes, context, team, infrastructure, and domain requirements.
• Use multiple languages when appropriate; focus on architecture and design quality rather than ideology.
• Senior developers should optimize for results, not for language purity or tribal winning.
