New submission from Peter [EMAIL PROTECTED]:
Following code:
fp = open(delete.me, r+t)
fp.readline()
fp.write(New line \n)
fp.close()
Won't do anything. I mean nor writing to file, nor raising exception.
Nothing.
I can't find any note about this crap. So, it is the best place for

I tried this on windows 2000:
# create a file with some text
open(delete.me,w).write(some text\n)
fp = open(delete.me, r+t)
fp.readline()
'some text\n'
fp.write(New line \n)
Traceback (most recent call last):
File stdin, line 1,

Amaury Forgeot d'Arc, your example really raise IOError 0
Thing is that you had 1 string in the file
Here is it:
open(delete.me, w).write(first\nsecond\nthird)
fp = open(delete.me, r+t)
fp.readline()
'first\n'
fp.write(Newbie)
fp.close()
Amaury Forgeot d'Arc [EMAIL PROTECTED] added the comment:
Yes, the exact behaviour depends on multiple aspects.
You should follow the C library conventions:

For the modes where both read and writing (or appending) are allowed
