Key Highlights
- 30,000+ developers surveyed by PSF and JetBrains in the 2025 State of Python Survey—the largest yet—revealing 50% have less than 2 years experience.​
- Data and AI now dominate: 51% of developers use Python for data exploration/processing (vs. web 46%), signaling a permanent shift in the language’s center of gravity.​
- FastAPI exploded from 29% to 38% adoption in one year—a 31% jump—driven by data scientists and AI engineers needing to expose models via APIs.​
- Python 3.14 removes the GIL (Global Interpreter Lock): Free-threaded Python enables 3-7x performance improvements for multi-threaded tasks; yet 83% of developers still run outdated Python versions.​
- For India: Aligning skilling curricula with data/AI, standardizing framework training (FastAPI, async), and managing technical debt in government IT systems are urgent policy priorities.​
The Python Inflection Point
The Python ecosystem reached a tipping point in 2025. For the first time in the language’s history, over half of all surveyed developers have less than two years of professional experience. This isn’t a sign of decline—it’s the opposite. It’s evidence that Python has transcended “niche language for scientists” to become the global entry point into coding itself. jetbrains​
Simultaneously, the language’s dominant use-case shifted decisively. Data, AI, and machine learning—not web development—now occupy Python’s center stage. Yet web frameworks are resurging, led by FastAPI’s explosive 31% year-over-year growth.​
For India, this presents both an unprecedented opportunity and an urgent crisis. With 1.6 million recognized startups, 65% of the population under age 35, and aggressive digital transformation roadmaps (Digital India, PM Gati Shakti, e-governance), India should be positioned to harness this Python wave. Instead, our skilling ecosystem, higher education curricula, and digital governance infrastructure remain woefully misaligned with global trends.
This blog unpacks the 2025 Python landscape and what it means for India’s policy choices.
Who Are Today’s Python Developers?
The New-Developer Explosion
The 2025 Python Developers Survey shattered previous records with over 30,000 respondents from 200+ countries.​
The demographic makeup reveals a seismic shift:​
- 50% have less than 2 years professional experience
- 20% have less than 1 year of Python coding
- 67% of computer science learners worldwide use Python for both work and study
- 72% use Python for work; 28% for learning/hobby
This is unprecedented. In most mature programming languages, the experience distribution is inverted—most developers have 5+ years experience. Not Python.
Why Python Became the Universal Entry Language
Python’s beginner-friendly design is the obvious reason—readable syntax, instant feedback, massive library ecosystem. But there’s more:
Accessibility: Python runs on any device (laptop, cloud, raspberry pi). The barrier to entry is zero.​
Career Pathway: Unlike Java or C++ (historically for “professionals”), Python signals you can immediately work on trendy problems (AI, data science, automation) without years of foundational CS knowledge.​
Startup Economics: India’s 1.6 million startups disproportionately hire Python developers because speed-to-market trumps architectural purity. A junior Python developer can contribute day-one.​
In 2025, the pipeline is inverted: India must now focus on upskilling absolute beginners and intermediate developers in modern frameworks and data engineering, not just foundational programming.
Yet most government-sponsored training centers still use outdated curricula. This is a critical policy gap.
Python’s Use-Case Shift—Data, AI, and the Web Rebound
Data and AI Now Dominate
The 2025 survey revealed a decisive pivot toward data and AI:​
| Use Case | 2023 | 2025 | Change |
|---|---|---|---|
| Data exploration/processing | 47% | 51% | +4 pp |
| Web development | 42% | 46% | +4 pp |
| DevOps/automation | 23% | 25% | +2 pp |
| Machine Learning | 13% | 13% | Flat |
| Data engineering | 8% | 10% | +2 pp |
Why this matters: Python was long positioned as “the web development language” (Django, Flask rivaled Ruby on Rails). That narrative is now obsolete. Python’s primary identity is now “the data and AI language”—used by researchers, data scientists, ML engineers, and increasingly, by domain specialists (biologists, economists, climate scientists) doing exploratory data analysis.
Web Development’s Surprise Rebound
Yet web development didn’t decline—it rebounded from 42% (2023) to 46% (2025).​
Why? The FastAPI explosion.
The FastAPI Phenomenon
The Numbers
FastAPI adoption jumped from 29% to 38% in a single year—a 31% increase.​
For context:
- Django: Held steady at 35% (mature, stable adoption plateau)
- Flask: Slight decline to 34% (legacy use, limited innovation)
- FastAPI: Skyrocketing, now #1 web framework among new projects ZestMinds​
Why FastAPI?
FastAPI is purpose-built for the modern API economy:​
- Async-first: Non-blocking requests, enabling 10,000+ concurrent users on modest hardware
- Built for AI integration: Designed to expose ML models via REST APIs or WebSocket streams
- Auto-documentation: Interactive Swagger docs generated automatically—critical for team collaboration
- Type hints and validation: Pydantic-based validation prevents common runtime errors
- Performance: Benchmark rivaling Node.js (10x faster than Flask)​
Strategic Implications for India
FastAPI’s rise signals API-driven government platforms and startup ecosystems. Key opportunities:
- PM Gati Shakti and Digital Public Infrastructure (DPI): Building APIs for multimodal logistics, port terminals, and supply chain visibility.
- e-Governance Platforms: Reimagining India Stack (UPI, Aadhaar) as microservices with FastAPI backends.
- MSME Digitalization: Low-cost APIs enabling small businesses to sell inventory, track orders, and integrate with e-commerce platforms.
- AI-as-a-Service Startups: India’s AI startups (e.g., in healthcare, agriculture) can use FastAPI to package models as services for enterprise clients.
The Hidden Cost of Technical Debt—Old Python Versions
The Upgrade Crisis
Here’s a sobering statistic: 83% of developers run outdated Python versions.​
- 35% use Python 3.12 (released October 2023—18 months old)
- 21% use Python 3.11 (released October 2022—2.5 years old)
- 15% use Python 3.10 (released October 2021—3.5 years old)
- 6%Â still use Python 3.9 or older
The justification: “It works. Upgrading is risky. Why touch it?”
The Economic Cost
Upgrading Python versions yields approximately 42% performance improvement with zero code changes (via interpreter optimizations and JIT improvements).​
For a medium-sized firm (50 servers, 10 million requests/day):
- Annual cost of running outdated Python: ~US$420,000 (wasted compute, increased latency, higher cloud bills)
- Annual cost for large enterprise (500 servers): ~US$5.6 million
Over a 5-year lifecycle, that’s US$2.1 million to US$28 million in pure waste—not counting security vulnerabilities, which are exponential.​
Digital Governance Debt
India’s digital governance infrastructure—income tax filing systems, passport processing, pension management—likely runs on similar “it works, don’t touch” logic.
Policy imperative: Mandate security and performance audits of government software stacks every 18 months, with mandatory upgrades to supported versions. The cost of a single data breach (e.g., Aadhaar exposure) far exceeds the upgrade cost.
Rust as a Performance “Secret Weapon”
The Polyglot Stack Revolution
Between 25–33% of new native-code uploads to PyPI (the Python package repository) now use Rust for high-speed components.​
What does this mean?
Developers are writing Python + Rust hybrid systems:
- Python: High-level logic, easy to modify, handles user interaction
- Rust: Performance-critical components (cryptography, data serialization, signal processing)
Examples:
- Cryptography libraries: Use Rust for AES-256, SHA-3 (100x faster than pure Python)
- Data processing: Polars (Rust-backed dataframe library) is 50–100x faster than Pandas for large datasets
- ML inference: ONNX Runtime (Rust backend) accelerates model serving by 5–10x
Strategic Implication for India
India’s tech education and R&D ecosystem have historically focused on single-language mastery (Java engineers, Python engineers, C++ engineers). This is now a competitive disadvantage.
The future requires polyglot engineers—people who can write Python intelligently but understand when to drop to Rust, C++, or even Assembly for performance-critical paths.
Policy imperative: Engineering colleges must introduce multi-language curricula, not reinforce single-language silos. NASSCOM, AICTE, and startup incubators should incentivize “polyglot engineer” certifications.
The Near Future—AI Assistants, Free-Threaded Python, and Mobile
AI Coding Assistants: From Niche to Mainstream
Current adoption:
- 11% of developers actively use AI coding assistants (Copilot, Claude, ChatGPT)
- 49% plan to adopt soon​
By 2026: Over 60% of professional developers will use AI assistants daily—not as “nice to have,” but as essential productivity tools, like Git and IDEs.
Implication for India: Government recruitment exams, competitive programming contests, and corporate hiring processes all need to evolve. Using AI assistants will become normal; the skill will be in knowing what to ask and validating the output, not in raw coding speed.
Python 3.14: Free-Threaded Python (No More GIL)
The Global Interpreter Lock (GIL) has handicapped Python since 1992. It prevents multiple threads from executing Python bytecode simultaneously—even on 8-core machines, threading stays single-core.
Python 3.14 (2025–2026) introduces “free-threaded Python”: An optional build that removes the GIL entirely.​​
Performance Impact (real benchmarks):​
| Workload | Standard Python 3.14 | Free-Threaded Python 3.14 | Speedup |
|---|---|---|---|
| Prime number computation (4 threads) | 5.98s | 1.55s | 3.86x |
| Multi-file I/O (20 files, 4 threads) | 20.77s | 5.13s | 4.05x |
| Matrix multiplication (8 threads) | 43.95s | 4.56s | 9.64x |
This is transformational for data science, ML training, and scientific computing where multi-core utilization is critical.
Mobile Python (iOS and Android)
Python is underway to become officially supported on iOS and Android—potentially through BeeWare and PEP 738 initiatives.​
If realized, this could democratize mobile app development, reducing the need for Swift/Kotlin expertise and enabling rapid prototyping of AI-driven mobile apps.
India-specific opportunity: If mobile Python matures, startups can build consumer-facing AI apps (voice assistants, agricultural advisory) without separate iOS/Android teams.
Implications for India’s Digital and Education Policy
Skilling and Education
Current Gap: India’s coding bootcamps, college CS programs, and government skilling initiatives (PMKVY) focus on foundational programming (syntax, algorithms, data structures). They lag in modern frameworks and polyglot thinking.
Required Actions:
- Integrate FastAPI, async programming, and type-hint best practices into college curricula by 2026.
- Introduce “AI assistant literacy” as a core skill in competitive exams and corporate training.
- Promote polyglot engineering through multi-language bootcamps and university programs.
- Mandate GIL-free Python adoption in government and PSU IT projects within 24 months of Python 3.14 release.
Digital Governance and DPI
Current Problem: Indian government software stacks (income tax, passport, land records) run on aging architectures with significant technical debt.
Required Actions:
- Conduct mandatory performance and security audits of all government software every 18 months.
- Incentivize public-sector IT teams to upgrade to Python 3.14 free-threaded builds, with budgets for training and migration.
- Build modern APIs for legacy systems (e.g., exposing income tax filing via REST APIs for third-party integrations).
- Invest in DESI (Data Science and Engineering)Â as a distinct, high-priority skill for government digital transformation.
Innovation and Industry
Current Problem: Indian startups often prioritize speed-to-market over architectural purity, leading to technical debt cycles.
Required Actions:
- Incentivize startups to adopt modern Python toolchains (FastAPI, free-threaded Python) through cloud credits or tax breaks.
- Promote “security-by-design” in startup incubators, with Rust and cryptography as baseline modules.
- Fund R&D into polyglot stacks (Python + Rust) tailored to Indian use-cases (e-commerce, fintech, agritech).
- Establish “Python Centers of Excellence” in tier-1 cities (Bangalore, Pune, Hyderabad) for advanced training in async programming, GIL-free Python, and AI assistants.
Key Decision Points for Policymakers and Institutions
Decision 1: Curriculum Alignment
Question: Should Indian engineering colleges adopt FastAPI, async programming, and polyglot frameworks as core coursework, or remain language-agnostic?
Answer: Adopt frameworks by 2026. Language-agnostic principles are important, but India’s competitive position depends on developers hitting the ground running in modern stacks, not re-learning fundamentals on the job.
Decision 2: AI Assistant Integration
Question: Should competitive exams (GATE, JEE) and hiring processes change given AI coding assistants?
Answer: Yes. Exams should test architectural thinking and validation skills, not raw coding speed. Hiring should prioritize “knowledge of what to ask AI” and “ability to catch AI mistakes” over traditional leetcode problems.
Decision 3: Government IT Modernization
Question: Should all government IT projects migrate to Python 3.14 free-threaded builds?
Answer: Selectively. For high-traffic systems (income tax portal, passport processing, vaccination registries), migration is economically justified (42% performance improvement = massive cloud savings). For legacy COBOL/mainframe systems, prioritize integration APIs instead of full rewrites.
Conclusion
The 2025 Python landscape—50% beginners, data/AI dominance, FastAPI’s explosive growth, GIL removal, and AI-assisted coding—is reshaping the global software industry.
For India, this is simultaneously the greatest opportunity and the most urgent crisis in our skilling and digital governance roadmap.
Three years ago, India’s demographics looked perfect for tech leadership: 65% under 35, 1.6 million startups, massive digital transformation budgets (Digital India, PM Gati Shakti).
Today, without urgent alignment of education, policy, and infrastructure with Python 2025 trends, India risks sliding backward—training developers in outdated frameworks, running government systems on slow and debt-ridden code, and ceding AI/data science leadership to countries with modern, well-funded skilling ecosystems.
The fix is clear but requires speed and coordination:
- Ramp up FastAPI and async programming in college curricula immediately
- Modernize government IT stacks with Python 3.14, cloud-native approaches, and security-by-design
- Invest boldly in polyglot engineering and AI-assistant literacy
- Link innovation incentives to modern toolchain adoption in startups
