We'll need at least the two full examples (one not working, one working) to 
make a call here.

[issue26116] CSV-module. The example code don't work. Have to be: reader = csv.reader(csvfile, dialect=dialect)

2016-01-14 Thread SilentGhost 

SilentGhost added the comment:

Vasyl, this line in your code is causing the problem:

for row in readed:

The error reasonably clear states that it's due to your `fieldnames' parameter 
being non-iterable. Again, this has nothing whatsoever to do with `dialect' 
argument and documentation of Sniffer. 

Please, do not open new issues about this. This is not a issue with csv library 
or its documentation. Try to use use stackoverflow or python-tutor list to get 
help on this.

2016-01-14 Thread Georg Brandl 

Georg Brandl added the comment:

Thanks!  Now the reason is clear: You use csv.DictReader instead of csv.reader. 
csv.DictReader has a different argument list - for DictReader the second 
argument is `fieldnames`.
