Can I count in reverse order with range?
I recall being able to count backwards with range but have not really been able to do so with a couple of blocks I've tried to use. When I pass a -1 as the third arg in range nothing seems to happen. Am I doing something wrong here?
backwards = [ 'tac', 'esuoheerT', 'htenneK', [5, 4, 3, 2, 1], ] def reverse(arg): letlist =  for char in arg: print(char) letlist.append(char) print(letlist) newword=  count = len(letlist) print(count) for i in range(count, -1): print(i) newword.append(letlist[i]) return newword print(reverse('words'))
for i in range(count, -1):, you could try
for i in range(count, 0, -1): so that
i will start at the value of
count and continue until
i is not greater than 0. This will give you an
IndexError: list index out of range for its first value of
letlist[len(letlist)] is not valid. Using
range(count - 1, -1, -1) would solve that issue.
You could simplify your code by returning
