Beginner Tips for Learning Python Programming Online

While learning as a beginner programmer, you should follow these tips which will help you to deal with the new concepts:

Tip #1: Practice your code everyday

It is important to have consistency while learning any new programming language. It is important that you should make commitment to write code every day. As it will play with your muscle memory which is a very important part in programming.

Tip #2: Make notes

It is important for anyone who is new to programming to take notes. In fact, some of the research have suggested that taking notes by hand is most helpful way for long-term knowledge retention especially beneficial for those who goal of become a full-time python developer. This practice will help you when you start working on projects. This practice of writing code can also help you plan and understand your code before you write it on the computer. This will save a lot of your time when you have to write codes for functions and classes, as well as it will make you understand how they are interacting.

Tip #3: Use Interactive Python shell

Whether you are new Python data structures (dictionaries, lists, strings etc.), or you are debugging an application, the best learning tools is interactive Python shell.

To use the interactive Python shell, first you should install Python on your computer. The step-by-step installation procedure of python you can learn in this tutorial. To activate and use the interactive Python shell, simply open the terminal on your system and run python or python3 depending on your version of installation. Now that you know shell is open, you can write code.

Tip #4: Take Breaks for better learning

Exercising both mind and body is important while studying this will help you to absorb the concepts.

Taking short breaks is important for an effective study session, mainly this will help you in taking a lot of new information.

Tip #5: Always try to be a Bug Bounty Hunter

Hitting a bug is applicable when you start writing a complex program. Surely, there is a high possibility of hitting a bug into your code. Don’t get frustrated, it happens with everyone! Instead, grip these moments as a pride and think of yourself as a bug bounty hunter.

It is important to have a methodological approach while debugging the code, which will help you to find where your code is breaking down. Going through your code step by step in its executable order and make sure each part of code works is a great way you want it to do.

Tip #6: Make it collaborative

Always try to surround yourself with other learners. This will help you to share and gain the tips and tricks you learn along the way.

Tip #7: Teach

You would have heard that the appropriate way to learn something is teach that concept to other after learning it. This is very true when it comes for learning Python as well.

Tip #8: Ask questions and always try to answer it.

You should always ask question. Asking questions will help you to gain new knowledge on certain thoughts, and by answering questions you will recollect all your previous knowledge. Recalling and sharing concepts with others and hearing it again will help you to recollect your knowledge, as well as make your brain to work.

Tip #9: Try to Build Some Small Projects

Always try to build small project for each concept. This will help you build confident of writing Python program, as well as this will help you to develop the muscle memory. Once you have a solid foundation on basic data structures (dictionaries, strings, sets, lists), object-oriented programming, and writing classes. This will also teach you the most of your programming concepts. For the best of career growth, check out Python training course to get certified. Also, Intellipaat is providing a free Python interview questions and answers, which will help to excel your career.
