Python remains one of the most popular languages for starting a career in IT. But what exactly should a novice developer know to get a junior position?
Let's figure out where to start and what to look for.
🐍 1. Basic Python syntax
Variables and data types (
int,float,str,bool).Conditions (
if-elif-else) and loops (for,while).Functions and parameters.
Working with strings, files, and errors (
try-except).Basics of OOP: classes, objects, attributes.
🗂 2. Data processing and algorithms
Lists, dictionaries, sets, tuples.
Sorting, searching, working with a stack and a queue.
Simple algorithms (linear and binary search).
💡 Tip: practice on tasks from LeetCode (Easy) or Codewars (8–7 kyu).
🛠 3. Fundamentals of web development
How it works HTTP (GET, POST, response codes).
What is REST API.
One of the frameworks: Flask, Django or FastAPI.
💾 4. Databases
Write simple SQL queries (
SELECT,WHERE,JOIN).Understand the difference between relational and non-relational databases.
Use ORM (for example, SQLAlchemy or Django ORM).
🔧 5. Developer tools
Git — how to commit, push, pull, create a branch.
Virtualenv / venv - work with virtual environments.
requirements.txt — dependency installation.
Basic commands Linux (cd, ls, mkdir, grep).
🧪 6. Testing and debugging
Understand what unit tests.
Use
pytestor built-inunittest.Use debugger and logging (
logging).
📚 7. What else is checked during the interview
Principles of OOP (encapsulation, inheritance, polymorphism).
Understanding algorithmic complexity (Big O) at a simple level.
Ability to explain how your code works.
🚀 How to prepare faster
Do mini-projects: parser, ToDo-app, telegram bot.
Place the code on GitHub - this is a plus at the interview.
Take 1–2 Python and backend courses.
🐱 Where can I level up my skills?
In the attachment Code there are Python courses, practice projects, and algorithm development tasks. Plus, we have Telegram channel with useful articles is a great way to prepare for your first job.
