Should I change something in this programm

Question

I made a programm that explains lists in some degree.
I know its not perfect, but i want other peoples opinions on this, like what should i change, add, remove, rearrange.
I also couldnt think of a short name in the slicing sections so i just put some random words. Can anyone give me some ideas?

Answer 3

Mihaly Nyilas thank yoy for your feedback.
The 70 liness of code were beacuse i was doing this in mobile and i cant see some of the last lines of code (keyboard blocking)
And i think ive gotten rid of some of the reapeating code. Some of the reapeating code is beacuse i showed different ways to use them
