Who can teach me to write codes

Answer 1

You already started the Python Developer course. You will get the chance to write code in the lesson when you advance deeper. Keep doing the lessons, and you will eventually know how to write code.

Answer 2

In text data they said I should write a code

Answer 3

In the "Text Data" lesson, the first half is multiple choice, and in the second half you are introduced with the playground, which you can write your own code. In there, you can press "RUN" and see the result.

If you're planning to modify the code, just tap on the code window, then modify as you like.

And in fact, you can continue the lesson without modifying the code.
