Bug description:
I'd like to output all quotes verbatim, without any escaping/quoting, but this fails:
importcsvw=csv.writer(open('test.tsv','w'),delimiter='\t',quoting=csv.QUOTE_NONE)w.writerow(('"hello"','"world"'))# _csv.Error: need to escape, but no escapechar set
When I setescapechar='' orquotechar='', it also fails:
importcsvw=csv.writer(open('test.tsv','w'),delimiter='\t',quoting=csv.QUOTE_NONE,escapechar='')w.writerow(('"hello"','"world"'))# TypeError: "escapechar" must be a 1-character stringimportcsvw=csv.writer(open('test.tsv','w'),delimiter='\t',quoting=csv.QUOTE_NONE,quotechar='')w.writerow(('"hello"','"world"'))# TypeError: "quotechar" must be a 1-character string
I would suggest that underQUOTE_NONE, escaping of quotes should not be performed at all, or at least allow emptyescapechar /quotechar
The workaround / hack I found:
importcsvw=csv.writer(open('test.tsv','w'),delimiter='\t',quoting=csv.QUOTE_NONE,quotechar='\t')w.writerow(('"hello"','"world"'))
