After all it is a valid statement... it's an expression that fetches the close method object, and throws it away. to see what it evaluates to, try running the code from the interactive prompt (or add a print statement): f = open(foo, w) f.close built-in method close of file object at 0x00836B20 also see http://docs.python.org/ref/exprstmts.html http://docs.python.org/ref/attribute-references.html /F -- http://mail.python.org/mailman/listinfo/python-list

cannot write to file after close()
Hello Python-Gurus, == f = open(LOGFILE,'w') f.write(time + '\n') f.close command = 'ping -n 20' + target + '' + LOGFILE system(command) == produces an error saying that a file cannot be accessed because it is used by another process. I asume it is f which is used but don't understand why. Any ideas? Thanks a lot! Cheers, Rainer -- http://mail.python.org/mailman/listinfo/python-list
