π Essential Python Habits for Developers
1. Write Readable and Clean Code
- Follow PEP 8 guidelines.
- Use meaningful variable and function names.
- Keep code simple, consistent, and easy to read. ## 2. Practice Test-Driven Development (TDD)
- Write tests before writing the actual code.
- Use tools like
pytest
orunittest
. - Catch bugs early and build reliable software. ## 3. Understand Python Internals
- Learn how Python handles memory and variables.
- Understand scope, namespaces, and data types.
- Know the difference between mutable and immutable objects. ## 4. Use Built-In Functions and Standard Libraries
- Take advantage of Pythonβs extensive standard library.
- Use modules like
datetime
,itertools
,collections
, andfunctools
. - Avoid reinventing the wheel. ## 5. Keep Your Code DRY (Donβt Repeat Yourself)
- Eliminate redundant code through functions and loops.
- Refactor repeated logic into reusable components.
- Write modular, maintainable code. ## 6. Master List Comprehensions and Generators
- Write concise and efficient loops with list comprehensions.
- Use generators for memory-efficient iteration over large datasets. ## 7. Debug Like a Pro
- Use
pdb
,breakpoint()
, or IDE debuggers. - Debug incrementally and write reproducible test cases.
- Understand stack traces and error messages. ## 8. Use Virtual Environments for Dependency Management
- Isolate project dependencies using
venv
orvirtualenv
. - Avoid version conflicts.
- Save your environment using
requirements.txt
. ## 9. Read and Contribute to Open Source Projects - Study how professional code is structured.
- Learn version control with Git.
- Collaborate and give back to the developer community. ## 10. Practice Consistently and Build Real Projects
- Code regularly to reinforce your skills.
- Take on small personal or freelance projects.
- Solve coding challenges to improve problem-solving. Engineering Materials Mastery
