Not entirely true since the code uses string.split()
However since the split method of the string could

This I have now done by using eval(). But now I wonder whether that
is actually clever because it is supposed to be similarly
problematic as the input() function in terms of security.

They have different uses and input is very convenient at the >>>

Hello Steve,
thanks for all your help and comments.
What happens, though, is that with

my code is still defunct (whereas input() works):

Recall that we told you raw_input() returns a string, while
input() returns an integer if you typed an integer value.

input() automatically evaluates whatever the user types as a Python
expression

you should really use raw_input to get the info from the user,
and then convert it to a number.
