I'm trying to add some fields to a shapefile using pyshp. The code I have to far is:
import shapefile
Read in our existing shapefile
r = shapefile.Reader(r"C:...\Edit_SHP\TracksLines.shp")
Create a new shapefile
w = shapefile.Writer(r"C:...\Edit_SHP\TracksLines_edited.shp")
Copy over the existing fields
w.fields = list(r.fields)
Copy over the records
for shaperec in r.iterShapeRecords():
w.record(*shaperec.record)
w.shape(shaperec.shape)
w.field('test')
The issue is that when I try to add a new field all the records already present on the shape are messed up.
How can I keep the same numbers of records, when adding new fields?
