python - Functions with strings -

i working pyhton on codecademy , stucked in 1 part. goal this: "define function called reverse takes string 'text' , returns string in reverse. may not use reversed or [::-1] this." did 1 , not working this:

t = raw_input("enter: ") def reverse(t):     x = []     in range(len(t)):        x.append(t[len(t) - - 1])     print ''.join(x) 

but when working.

t = raw_input("enter: ") x = [] in range(len(t)):    x.append(t[len(t) - - 1]) print ''.join(x) 

what wrong first one?

the first not work because, you're not calling reverse function on t.

def reverse(t):     x = []     in range(len(t)):         x.append(t[len(t)-a-1])     return ''.join(x)  t = raw_input("enter: ") print(reverse(t)) 

in example you're obtaining input, doing nothing it.
