Oh, so that's what the random integer in this code means. Good to know this on this web here. I hope that you can share more details about this code with us, that would be fantastic news for me.

I am looking for a website link where they can explain to me how I can use the range and floor functions. I want to write a code and it is important to use this in that code.
