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
In 3.x, t vs b modes actually mean to read/write text (str (unicode)) vs binary (bytes, for instance) objects.
