Can anyone enlighten me about slicing in python and how it's used?

Answer 1

check this video.

Answer 2

No, no, it is perfectly reasonable, when you start a program, to expect that it either does stuff or tells you what it needs and not just fail. It's only that it's hard to do here. After a while you get used to it...

Answer 3

And after you've done that, if you want to look at some practical applications, I'd be happy if you took a look at my examples. :-)

(If something is confusing, please ask.)

Answer 4

HonFu your codes looks awesome but at the moment I'm not able to understand them much but I'll check them later for sure when I'll catch up.😀 and the third code (owl matrix asserter) is showing error

Answer 5

partha, the error happens because the program expects you to do a special kind of input first.

Unfortunately we have no real way here to interact with the user (except in web programming), so we can only explain in a comment, how it works.

I have changed other scripts in order that if you don't input anything, there's a default data set. Mostly I don't use inputs anymore and let people enter directly in the code instead.

About my codes: You can move through a slice in so many ways (startpoint, endpoint, direction, stepwidth) that you can do a lot of stuff with it, like move within a geometrical shape like a square or a cube.

Mostly squares get modelled using two values for a point (x and y), but with Python slices you can just write a long list of numbers and make it behave like a square or a cube - so I was having a bit of fun doing exactly that. ;-)

oops sorry then HonFu it's my lack of knowledge 😔
