What the error means is this :
You tried to convert the number in the string "" (empty string) to
a float (decimal).
That can't be done -- the string doesn't contain a number. (perl, of
course, will magically turn it into the number 0.0 without a single
warning)
The problem could be caused by a programmer error, or it could be due
to incorrect input, or it could be due to the input being correct but
not what the programmer expected it to be.
If the other solutions don't work for you (or if you really want to
see the python one work :-)), can you post the data somewhere since we
already have the code and perhaps someone will debug it.
