Issue with Pythonic Solution for reverse_string

[anthonyattard]

The following solution does not work:

class ReverseStringAlt(object):

    def reverse_string_alt(string):
        if string:
            return string[::-1]
        return string

    def reverse_string_alt2(string):
        if string:
            return ''.join(reversed(string))
        return string

[ghost]

class ReverseStringAlt(object):
def reverse_string_alt(self,string):
if string:
return string[::-1]
return string

a=ReverseStringAlt()
s=input()
k=a.reverse_string_alt(s)
print(k)

@Harshavika is my solution correct?

@anthonyattard , this is your code which I just changed a little bit to run which gives correct answer.
