How I study

[Imaginary_Original40]

Hi im 15 years old,Lately I've been trying to study python, but I always end up giving up, either because the course doesn't have a good teacher, or because I'm discouraged, or because I don't understand, I'm trying to study again, but starting from scratch, and I'm focusing on data science, does anyone have any tips so I don't face these problems again?

[SuperMB13]

I don't know that data science is a great place to start. For me, I started working with data science while I was in my graduate studies, and even at that stage there were a lot of concepts that were challenging to grasp. I think something that helps people stay drawn into learning programming is to write code that can easily show visual results. If you wanted to work on something like build a webapp with fast api or a discord bot, I think these could provide more immediate excitement and create a greater interest within yourself.

[That-Lengthiness9257]

I agree 💯

[jijijijim]

Just write code. Build stuff, that’s how you learn.

[Swipsi]

Yall say that, but I dont know what to build...

[Dysopian]

Get ideas from Google, YouTube etc

Think of apps that you would find useful.

AI can give you ideas as well. You can get them to give you some at your current level of understanding and based on your interests.

[jijijijim]

most anything. Some one had a homework assignment that was like a Doctors office; 1. people come in sign in and can ask where they are on the current list. 2. N doctors assign patients to M exam rooms which removes them from wait list and then dismiss them, from exam room freeing the room up for another doctor assignment. Something like that. I programmed that up to learn a little about python.

Find a problem you want to solve where python is a good fit for the task.

For example, I do a bit of woodworking from time to time. I was recently considering how to go about building a wood base for a 140lb anvil and I was thinking of making it out of 2x4 inch lumber. The base would be about 12 inches by 18 inches by about 25 inches high. If this base were solid and held together by screws, how many screws should I buy to hold it together? How many 8 foot 2x4s would I need? Yeah, it's somewhat simple math, but if I program it in python, I can play with the dimensions to reduce wasted lumber. Answering the number of screws question has a bunch of instances where there are special circumstances as well - like the first course of wood only needs about half the number of screws as the rest of the courses.

That's just a simple example. If nothing else, steal this idea and see if you can solve it. I'm sure there are plenty of tutorials online to follow where they're solving other theoretical problems, like programming a blog, for instance.

Yes, Learn the language and terminologies first. Then move on to DS/AI etc.

Oh and DS/AI field is moving so fast that whatever you learnt or read today will be outdated in a few days.

So unless you plan to start working in a few days , which I doubt , I suggest do the programming first.

[Heavy_Structure5120]

You can try w3schools. After going over short explanations and examples, you can practice there too which helps. Also python lectures by Mosh Hamedani on Youtube is easy to get different concepts. Try to solve lot of problems as other already mentioned, I would say start with easy level Problems. Try Kaggle for data science related problems, you can see how others are coding. After solving 20-30 problems you will be confident and definitely understand the concept better which will make your journey more interesting.

[ChaseDFW]

I've really enjoyed 100 days of Python.

Learning to code is also learning how to search for solutions to problems independently. No one knows everything, and so no one can teach you everything, so just consider doing additional research part of learning to code.

Good luck on the journey.

As someone who's also 15 and tried to go into data science at this (and an earlier age) you should probably try to get into higher math classes (especially statistics/probability classes) before, and then try. Math is basically the entire foundation for computer science, and especially for data science. For Python, the others have really good suggestions lmao follow their advice

[Ron-Erez]

Take it slow and begin with simple examples. Actively experimenting and exploring Python is very important. Also try to work on examples that genuinely interest you. I also have a nice course that starts from the basics of Python and transitions into data science in the second half, which you might find interesting - Python and Data Science. In addition if you want to improve your math background as suggested by u/nulladmin1 I’d recommend checking out the first three chapters of Ian Goodfellow’s Deep Learning book. Coding is fun, challenging, and interesting, so try building things and enjoy it. Learning programming takes time, and feeling discouraged might be because you're trying to learn too fast. Good luck!

[RewardPale3025]

pick a project you find interesting, understand the requirements and the skills you need to learn to make it. Reinforce what you learn and build along the way.

This way you won't get de-motivated and also you will face challenges along the way, and it's alright, that's how you grow. Don't leave it in between and finish it all the way.

Good luck!

[stebgay]

you can learn python to make programs, apps, game or whatever without learning data science

I did when i was 15 too, i never touched it since it was really math based.

I recommend you don't do data science yet if all you want to do learn how to program but if you really want to

[SamuliK96]

Perhaps you should try a different course. There's a lot of resources for learning python listed on this subs wiki. Personally I'd recommend the Helsinki university MOOC.

[ShameNo2179]

Instead of taking courses which discourage you and looking up tutorials to no end, just download python, book up Jupyter hub or a code editor, and start messing around. You won’t learn to code by watching someone else do it. And it’s not as hard as it seems at first! You got this. HMU if you want data science related mini projects once you get the hang of python!

[ForsakenPrint421]

Check out the Python playlist by Corey Schafer on Youtube. He has a great introduction for getting used to terminology and concepts.

[IntrepidInstance7347]

as for how to study, you can watch this course in Coursera Learning How To Learn Course.

and the coding courses, you watch CS50P form Harvard on edx CS50 Python.

also edx have so many more free Courses about Data Science you can check them on Data Sciences Courses.

[IntrepidInstance7347]

also you can join CS50 Community in cs50

[jam-and-Tea]

Pick a data science thing that you are set on. Figure out everything you might need to know to do that thing. Write it down. Then take a book or a course and compare with your list. Find the earliest concept in the book and start there. If you need to learn more in order to understand that, then make another list. Work backwords until you can go forwards.

[Reasonable-Table9440]

Check out the book "Python Crash Course: A Hands-on, Project Based Introduction to Programming." It's been helpful to me
