Question

I have code that makes a shapefile but the number of fields is dependent on certain factors. At the moment I’m testing it on input that I know produces 3 fields so have this code.

output = shapefile.Writer(shapefile.POINT)
for i in range(1,(input.fieldcount+1)):
     fieldname = "field" + str(i)
     output.field(fieldname,'C','40')

for i in range(len(output.item)):
       output.point(input.item[i].x,input.item[i].y)
        graphshp.record(input.field[0],input.field[1],input.field[2])

But I would like to change this line:

        graphshp.record(input.field[0],input.field[1],input.field[2])

So it’s not hard-coded.

Answer 1

Per the pyshp source:

You can submit either a sequence of field values or keyword arguments
of field names and values.

To submit a sequence of field values you’d do:

    graphshp.record( *input.field )

In case you’re interested, arbitrary argument lists are covered in Python’s excellent documentation.
