If I have the following data file, data.csv: 1 2 3 2 3 4 5 then I can read it in Python 2.4 on linux using:
import csv f = file('data.csv', 'rb') reader = csv.reader(f) for data in reader: print data OK, that's all well and good, but I would like to record the line number in the file. According to the documentation, each reader object has a public 'line_num' attribute http://docs.python.org/lib/node265.html and http://docs.python.org/lib/csv-examples.html supports this. If I now change the loop to read: for data in reader: print reader.line_num, data I'm presented with the error: AttributeError: '_csv.reader' object has no attribute 'line_num' This has floored me. I've even looked at the source code and I can see the line_num variable in the underlying _csv.c file. I can even see the test_csv.py code that checks it! def test_read_linenum(self): r = csv.reader(['line,1', 'line,2', 'line,3']) self.assertEqual(r.line_num, 0) I suspect this is something so obvious that I just can't see the wood for the trees and I will kick myself. Any ideas? Cheers Duncan _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
