Hi Klas,

The join() method requires that every element in the 'line' should be a
string.  It's a function that takes a sequence of strings, and returns a
string.

But many of your example data lines have numbers.  For example:

    ['03003365', ';', 'AB', ';', '03003359', ';', 'AB', ';', '8', ';',
     80, ';', '8', ';', '-', ';', '', ';', '-', ';', 'YES']
     ^^

has the number 80 in there.


You can probably do something like:

     lineData = ' '.join([str(x) for x in line])

to first pass each element through the str() conversion function, and then
join those strings together.


Hope this helps!
