How to avoid it:

  • Start using Git from the beginning, even for small personal projects.
  • Learn the basic Git commands and workflow (commit, push, pull, branch, merge).
  • Use platforms like GitHub or GitLab to store your repositories and collaborate with others.
  • Make frequent, small commits with descriptive messages to track your progress.

6. Ignoring Code Style and Best Practices

When starting out, many programmers focus solely on making their code work, neglecting proper formatting, naming conventions, and other best practices.

Why it’s a problem: Poor code style makes your programs harder to read, maintain, and debug. It can also make it difficult for others to understand and collaborate on your code.

How to avoid it:

  • Familiarize yourself with the style guide for your chosen programming language (e.g., PEP 8 for Python).
  • Use consistent indentation, naming conventions, and commenting practices.
  • Learn and apply principles of clean code, such as DRY (Don’t Repeat Yourself) and SOLID.
  • Use linting tools and code formatters to help maintain consistent style.

7. Not Debugging Effectively

Ineffective debugging is a common issue among beginners who often resort to guessing or making random changes to fix errors.

Why it’s a problem: Poor debugging skills can lead to wasted time, frustration, and the introduction of new bugs while trying to fix existing ones.

How to avoid it:

  • Learn to use debugging tools provided by your IDE or development environment.
  • Practice reading and understanding error messages instead of immediately searching for solutions online.
  • Use print statements or logging to track the flow of your program and identify where issues occur.
  • Break down complex problems into smaller, testable parts to isolate issues.
  • Learn and apply systematic debugging techniques, such as the scientific method of hypothesis and testing.
