Python Developer
Python Developers build backend services, scripts, and data pipelines across a huge range of domains — from FastAPI microservices to Django monoliths to one-off automation scripts. Their daily English covers explaining an async/await bug in a pull request, writing a dependency-pinning rationale in a packaging RFC, describing test coverage gaps to a lead, and presenting an API design in a review. This path builds the vocabulary for the most widely used language in IT overall.
Topics covered
- Python ecosystem & tooling
- Backend frameworks

Vocabulary spotlight
4 terms every Python Developer should know in English:
A function defined with `async def` that can be paused and resumed, allowing other code to run while it awaits an I/O operation
"Wrapping the database call in a coroutine let us handle ten times more concurrent requests without adding threads."
A pytest function that provides a fixed baseline — data, a mock, or a connection — that tests can reuse without repeating setup code
"We moved the test database setup into a fixture so every test starts from a clean, known state."
A pattern where a function declares what it needs as parameters, and the framework supplies them automatically, common in FastAPI route handlers
"FastAPI resolves the `Depends(get_current_user)` dependency injection before the route function even runs."
An isolated Python installation with its own packages, preventing dependency conflicts between projects
"The build failed because someone installed a package globally instead of inside the virtual environment."

Real-world scenarios you'll practise
- Explaining why an `await` was missing in a code review, and what silently broke because of it
- Writing a short RFC justifying a switch from Poetry to uv for dependency management
- Presenting test coverage gaps to a tech lead after a production incident traced to an untested branch
- Describing the trade-offs between FastAPI and Django for a new internal service in an architecture review

Frequently Asked Questions
What English skills do Python Developers most need to improve?+
Python Developers most commonly need to improve: technical vocabulary (the correct English terms for domain concepts), collocation accuracy (using the right verb for each action), written communication (bug reports, PR descriptions, technical docs), and spoken communication for standups, code reviews, and stakeholder meetings.
How long does the Python Developer learning path take?+
The Python Developer learning path contains 20–40 hours of material studied comprehensively. Most learners focus on the highest-priority modules first and return to the rest over time. Spending 30 minutes per day for 4–6 weeks produces noticeable improvement in workplace English.
What vocabulary should a Python Developer prioritise first?+
Start with the vocabulary that appears most in your daily work — terms you read in documentation, use in commit messages, and hear in meetings. The Python Developer path begins with the most frequent vocabulary clusters before moving to advanced communication patterns.
Are there interview exercises for Python Developer roles?+
Yes. The Python Developer path includes role-specific interview question modules with model answers and key phrases — the actual questions interviewers ask and the vocabulary needed to answer them fluently. There is also a dedicated Interview Practice hub for general interview skills.
Does this path include pronunciation help?+
Yes. The path links to pronunciation exercises for the technical terms most commonly mispronounced in this domain. The Pronunciation hub includes drills for acronyms, silent letters, word stress, and minimal pairs — all in IT context.
What are the most common English mistakes Python Developers make?+
The most common mistakes: incorrect collocations (using the wrong verb with a technical noun), false friends from L1, tense errors when narrating past incidents or walkthroughs, and using overly formal or overly casual register in written communication.
How do I improve my English for code reviews?+
Learn the standard code review collocations: approve a PR, request changes, leave a nit, address feedback, block a merge, resolve a conversation. Use hedging language for suggestions: "This might be cleaner as…", "Have you considered…?". The Collocations section includes a dedicated Code Review set.
Can I use this path alongside my daily work?+
Yes — the path is designed for working professionals. Each exercise set takes 10–15 minutes. The most effective approach is to study a vocabulary module before a meeting or task where you'll use that vocabulary, then practise immediately after. Context-linked practice produces much faster retention.
Is the content free?+
Yes, completely free. No registration required, no payment, no time limit. All vocabulary modules, exercises, glossary entries, and learning path guides are open access.
How do I track my progress through this path?+
Progress is tracked in your browser's local storage — completed exercise sets are marked with a checkmark when you return. No account is needed. You can bookmark specific modules and use the exercises overview to see which sets you've completed.
