9 things to do when you’re stuck in coding:

🔍 Read the error message carefully — it often tells you the issue

✍️ Rubber duck debugging — explain your code out loud

🧩 Break the problem into smaller parts

🧠 Revisit the logic — not just the syntax

❓ Google the error or issue with specific keywords

🛠️ Use console logs or print statements to trace the flow

⏸️ Take a short break — come back with a fresh mind

👥 Ask for help — forums, friends, or mentors

📖 Check the official documentation or trusted sources

How to get job as python fresher?

1. Get Your Python Fundamentals Strong
You should have a clear understanding of Python syntax, statements, variables & operators, control structures, functions & modules, OOP concepts, exception handling, and various other concepts before going out for a Python interview.

2. Learn Python Frameworks
As a beginner, you’re recommended to start with Django as it is considered the standard framework for Python by many developers. An adequate amount of experience with frameworks will not only help you to dive deeper into the Python world but will also help you to stand out among other Python freshers.

3. Build Some Relevant Projects
You can start it by building several minor projects such as Number guessing game, Hangman Game, Website Blocker, and many others. Also, you can opt to build few advanced-level projects once you’ll learn several Python web frameworks and other trending technologies.

The best doesn't come from working more.

It comes from working smarter.

The most common mistakes people make,
With practical tips to avoid each:

1) Working late every night.

• Prioritize quality time with loved ones.

Understand that long hours won't be remembered as fondly as time spent with family and friends.

2) Believing more hours mean more productivity.

• Focus on efficiency.

Complete tasks in less time to free up hours for personal activities and rest.

3) Ignoring the need for breaks.

• Take regular breaks to rejuvenate your mind.

Creativity and productivity suffer without proper rest.

4) Sacrificing personal well-being.

• Maintain a healthy work-life balance.

Ensure you don't compromise your health or relationships for work.

5) Feeling pressured to constantly produce.

• Quality over quantity.

6) Neglecting hobbies and interests.

• Engage in activities you love outside of work.

This helps to keep your mind fresh and inspired.

7) Failing to set boundaries.

• Set clear work hours and stick to them.

This helps to prevent overworking and ensures you have time for yourself.

8) Not delegating tasks.

• Delegate when possible.

Sharing the workload can enhance productivity and give you more free time.

9) Overlooking the importance of sleep.

• Prioritize sleep for better performance.

A well-rested mind is more creative and effective.

10) Underestimating the impact of overworking.

• Recognize the long-term effects.
