Use the function's argument to get the input value, don't use input(). Not a kata issue.

I'm getting EOF error for the input line, although when i run it on my pc it works okay. so what's going on here?

The kata is fine, your code is not. Your answer has a trailing space.

#                                          here
#                                            v 
'ehT kciuq nworb xof spmuj revo eht yzal .god ' should equal 
'ehT kciuq nworb xof spmuj revo eht yzal .god'

There is an issue with this kata. I tested on my code editor and it was right. The Kata is not recognizing my answer as correct.
