depending on the data origin.)
Well, when I said you should catch the ValueError I didn't imply you
should ignore the error and supress any error messages. Of course this
depents on the use case. Maybe you want to raise another exception with
a more user friendly error message or you might want to skip the line
and just print a warning. :)
What I'm trying to say: When I give a script/program to a user who is
not a python programmer I don't want him to see an error message like
"ValueError: invalid literal for int() with base 10: 'abc'" as this
would help him in no way.
