Hi all
I can not write anything if I have read something.
the code as:
Python 2.4.3 (#69, Apr 11 2006, 15:32:42) [MSC v.1310 32 bit (Intel)]
on win32
IDLE 1.1.3
a=open('d:\\a','r+')
a
open file 'd:\a', mode 'r+' at 0x00A147B8
a.read()
'11\n22\n33\n'
a.seek(0)
a.read(1)
'1'
a.write(a)
If you are opening a file for read and write access use rb+ or wb+.
Seeking and subsequent read/write will then work fine. Without the b,
Windows opens the file in its text mode. Don't seek on files opened
in text mode.
