I ran some experiments to see what the state of the world is. I generated a test.csv by exporting a CSV file from Numbers on OSX. This generated a file with Windows-style \r\n-terminated lines. The attached test_csv.py tries to open this CSV file in binary and universal newlines modes. Here's what happens on various platforms
Python 3:
* Linux: both binary and universal work
* OSX: binary errors out, universal works
* Windows: binary errors out, universal works
In both cases, the error was:
$ python3 test_csv.py
Traceback (most recent call last):
File "test_csv.py", line 5, in <module>
for row in spamreader:
_csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)
Python 2:
* Linux: both binary and universal work
* OSX: both binary and universal
* Windows: wasn't readily able to test
If I manually create a CSV file using TextEdit in plaintext mode on OSX, that produces a file with Mac-style \r-terminated lines. test_csv.py has the same results on this file on OSX (errors out in binary mode in Python 3).
