Files are iterators, and iterators can only go through the object once. Just
call next() before going in the for loop. Also, don't use "file" as a
variable name. It covers up the built-in type.

afile = open(file_name, 'r')
afile.next() #just reads the first line and doesn't do anything with it
for line in afile :
   print line
