New submission from Bobby Ocean:
I think this has been asked before, but it has been awhile and I think needs to
be re-addressed.
Why doesn't the CSV module handle NULL bytes?
Let me do some examples,
ascii = [chr(n) for n in range(256)] #No errors
print(ascii) #No errors
print(dict(zip(ascii,ascii))) #No errors
open('temp','r').writelines(ascii) #No errors
f=open('temp','r')
for line in f: print(line) #No errors
f.close()
Python hsndles every ascii chr, DEL, ESC, RETURN, etc. It displays those
characters, uses them as keys or values, etc.
But now try,
import csv
data = csv.DictReader(ascii)
for line in data: print(line) #NULL Byte Error
But we can quick fix this easily,
ascii.pop(0)
data = csv.DictReader(ascii)
for line in data: print(line) #No Errors
Doesn't it seem odd that we allow the use of every chr as keys, vslues, prints,
etc. but then we hold a special exception for using the csv module and yhat
special exception is not the ESC or DEL or any other non-printable chr, the
exception is for the NULL?
