I don't understand why this code doesn't work:
def reverse(string):
rev_string = []
for c in range(len(string)):
rev_string[c]=string[(len(string))-c]
str(rev_string)
return rev_string
print(reverse("google"))
and throws this error message:
IndexError: string index out of range
There are three problems in your code.
rev_string is an empty list you can not index it, you can use append instead;
you need to use ''.join instead of str to make a string from a list;
list index is 0 based, so max index is len(string) - 1:
def reverse(string):
rev_string = []
for c in range(len(string)):
rev_string.append(string[len(string)-c-1])
return ''.join(rev_string)
print(reverse("google"))
# elgoog
reversedbuiltin-function?return string[::-1]to reverse a string, if you are just trying to reverse a string without a loop.
