Python dominates in AI/ML and rapid development. Go excels in performance and concurrent programming.
Python¶
- Rapid development, huge ecosystem
- AI/ML dominance (PyTorch, TensorFlow)
- FastAPI, Django, Flask
- Slower runtime (GIL)
- Dynamic typing
Go¶
- Compiled, statically typed
- Goroutines — lightweight concurrency
- Fast builds, small binaries
- Simple language (25 keywords)
- Ideal for CLI, API servers, DevOps tools
Performance¶
- Go — 10-50× faster than Python
- Go — lower memory, better concurrency
- Python — async/await helps, but GIL limits
When to Use Which¶
- Python — AI/ML, data science, rapid prototyping, scripting
- Go — microservices, CLI tools, high-concurrency, DevOps
Both Have Their Place¶
Python for productivity and AI. Go for performance and infrastructure.
