Tools for transforming .csv files
The csv modules of 2.x and 3.x differ significantly on what type of file they expect - and how it is opened.
Python 2.x: If csvfile is a file object, it must be opened with the โbโ flag on platforms where that makes a difference.
Python 3.x: If csvfile is a file object, it should be opened with newline=''
also next(csvfile)
should return strings (= unicode)
They seem to work fine with sys.stdin
, sys.stdout
on linux, but it might be an accident.
Note: csv.reader(sys.stdin)
is quote common usage.
extract_map currently rewrites the map file on exit, ig it has changed.
When rewriting the rows are written in an unsorted way, so comparing what was changed with diff tools is hard.
create a new field with constant value
mkfield name [value]
The new field is the last one in the csv, field order is preserved.
