My solution

Also working:

def reverse_string(word):
reverse = “”
for i in range(len(word)):
reverse += word[-i-1]
return reverse

Tried this

def reverse_string(word):
    s = ''
    for index in range(len(word)-1, -1, -1):
        #print(word[index])
        s += word[index]
    return s`

And tried to shorten that function above by using list comprehensions:

def reverse_string(word):
    #print(len(word))
    return ''.join([word[index] for index in range(len(word)-1, -1, -1)])
