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") >>> a.seek(0) >>> a.read() '11\n22\n33\n' # it fails to write after reading >>> a.seek(0) >>> a.write("a") >>> a.seek(0) >>> a.read() 'a1\n22\n33\n' # it writes fine at the beginning of the file >>> it fails to write "a". but on my debian box, it works fine. the code on debian as: Python 2.3.5 (#2, Sep 4 2005, 22:01:42) [GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> a=open('/a','r+') >>> a <open file '/a', mode 'r+' at 0x4019dd60> >>> a.read() '11\n22\n33\n' >>> a.seek(0) >>> a.read(1) '1' >>> a.write("a") >>> a.seek(0) >>> a.read() '1a\n22\n33\n' >>> What's wrong here? is this a bug on windows platform. -- http://mail.python.org/mailman/listinfo/python-list
