for x in range(start, stop)
She showed in her video the stop is the number-1 which I think should be just number(without -1), since in range the stop value is excluded.
could someone tell me why she has to put -1 to the stop value-
if you see her video, she tried to find the prime number using this code for x in range(2, number - 1) which in my opinion she could remove the -1 because the range command will excluded the number.
Then, I check her solution, she only dis range(2,number), so the video and the solution are different.
