I’m experiencing a problem with the csv module in Python 3.1.2, and would greatly appreciate any help anyone can offer me. When writing csv files in Python 2.6, I open the output file as 'wb' to prevent a blank line being inserted after every line. Works like a charm. But I get an error if I do the same in 3.1; i.e if type the following sequence of commands: >>> import csv >>> outfile = open('c:/temp/test.csv', 'wb') >>> writer = csv.writer(outfile) >>> line = [1, 2, 3, 4] >>> writer.writerow(line) Traceback (most recent call last): File "<pyshell#26>", line 1, in <module> writer.writerow(line) TypeError: must be bytes or buffer, not str
Switching to >>> outfile = open('c:/temp/test.csv', 'w') makes it work, but I now have a blank line after each line when I open the file using Excel. Any thoughts or guidance on what I ought to be doing in 3.1 to fix the extra blank line problem? Thank you in advance Thomas Philips -- http://mail.python.org/mailman/listinfo/python-list
