how do practise what i studied?
I have no technical background, but I will to study coding language and develop a application my own... please suggest me a better way to train myself
First thing I would suggest is to pickup any programming language and learn basics(if you have already done it then very good👍) Now comes the application part For that I would suggest you to just pic up any project that you like(game, software,database etc) and start building it. Eventually you will encounter things that either you don't know or you don't know how to implement it, that is the point where WE(sololearn community) and GOOGLE come into picture. We are always there to help you to overcome that problem If you continue to follow these steps then you will not only make a new application but your knowledge will also increase
Applying what you have learnt is all you can do. I'm pretty sure that you would have learnt variable declarations, user input, conditional statements and loops. So now go google questions on these topic and try doing them on your own. Also when you learn lists, tuples and dictionaries, learn them well because there are a lot of functions used for manipulation. For now you can do these things before moving on further in the course.
Learn external modules, since you're using python, here is what I think you should start with: For web apps: Flask/Django For desktop apps: PyQt5
