Is Python or Go better for building APIs?
Go is superior for high-traffic APIs requiring handling 10,000+ concurrent requests with minimal infrastructure. Python (Django, FastAPI) is better for rapid API development when traffic is moderate (<5,000 RPS). Go's startup time of 12ms vs Python's 750ms matters at scale; Python's frameworks mature 2-3 years earlier.
Why does Go use so much less memory than Python?
Python requires a runtime interpreter and garbage collector running at all times, consuming 100-200MB baseline. Go compiles to native machine code with optimized runtime footprint. A simple Go service uses 15-30MB; equivalent Python service needs 120-180MB. This difference multiplies across 100s of microservices in large deployments.
Can Python compete with Go for microservices?
Python can build working microservices (FastAPI, Flask) but struggles at scale. Go handles 50-100x more concurrent connections with 1/10th the memory. Netflix migrated from Python to Go for real-time recommendation APIs, reducing latency 40% and infrastructure costs 35%. Use Python for internal tools; use Go for customer-facing, high-scale services.
Which language should a beginner learn first?
Learn Python first (40-60 hours to basic proficiency vs Go's 60-100+ hours). Python's readability makes programming concepts clearer. Most university CS programs teach Python. After mastering Python, transitioning to Go (learning systems thinking, pointers, concurrency) becomes natural. Many successful engineers follow this path.
Why is Go gaining adoption despite Python's larger community?
Go adoption is growing 3x faster annually (2020-2024 data) because it solves real production problems: containerization, cloud-native infrastructure, and microservices. Docker, Kubernetes, Terraform, and Prometheus are all Go. Cloud-first companies (AWS, Google, Stripe) increasingly prefer Go for backend services where performance and deployment simplicity matter.
