New submission from David W. Lambert <lamber...@corning.com>: Following instructions in http://docs.python.org/dev/3.0/library/csv.html#module-csv I opened file in binary mode. This might be simply a documentation problem or it may run deeper. Text mode works on red hat linux system.
Here's the use: >>> stream=open('csv','rb') >>> dialect=csv.Sniffer().sniff(stream.read(1024)) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/users/lambert/bin/python/lib/python3.0/csv.py", line 169, in sniff self._guess_quote_and_delimiter(sample, delimiters) File "/usr/users/lambert/bin/python/lib/python3.0/csv.py", line 210, in _guess_quote_and_delimiter matches = regexp.findall(data) TypeError: can't use a string pattern on a bytes-like object Here's the conflicting documentation statement: "If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference. ... see section Dialects and Formatting Parameters. All data read are returned as strings. No automatic data type conversion is performed." (Problem is that the binary file returnd data of type bytes.)
