Python 2.3 on Windows XP
The following works when run from the command line. import sys text = sys.stdin.read() # do something on the text # ... sys.stdout.write(text) But if the above code is used as a filter program that gets another programs output as shown below, it fails as shown. C:\>textGen.py | filter.py Traceback (most recent call last): File "C:\filter.py", line 4, in ? text = sys.stdin.read() IOError: [Errno 9] Bad file descriptor Any ideas on what is happening and how to fix it? -- http://mail.python.org/mailman/listinfo/python-list
