New submission from Logan:
Currently, DictWriter.writeheader() is defined like:
def writeheader(self):
header = dict(zip(self.fieldnames, self.fieldnames))
self.writerow(header)
It would be useful to have it return the value of writerow():
def writeheader(self):
header = dict(zip(self.fieldnames, self.fieldnames))
return self.writerow(header)
This would useful because:
1) It would match the behavior of DictWriter.writerow
2) It would enable DictWriter.writeheader to be used in within a generator
function (ala
