i dont know python but i can say how i started js. learn data structures started by doing simple thing like manipulating an array or object in functions. and start your 8th 7th kyu challenges. i'm still a begginer though so i hope it helps

Hey there,
I'm not sure about the material but I hope the following steps will help you go through this kata.
You are give an integer or you can say a number in this kata.

1. Try to figure out how you can - Convert an integer to its binary form in python
2. Also try figuring out - How to reverse a string/number in python
3. I am sure after this you will know how to go through the kata.

P.S - The figuring out part can be as simple as a google search 😉. Make sure you understand the concept and then try attempting the kata or it will be of no use.
