Hello Rolf,

I know this code because I have search a solution !
Your google code doesn't work ! No attribute "readlines".

 >>> import sys
 >>> data = sys.stdin.readlines()

Traceback (most recent call last):
   File "<pyshell#1>", line 1, in <module>
     data = sys.stdin.readlines()
AttributeError: readlines
