Hi Given the following two files in the same directory
Master.py: ---------- #!/usr/bin/python import Slave Slave.main() and Slave.py: --------- def main() : print "Hello World" Invoking Master.py under python-2.5.2 works just fine. 2to3 converts these to Master.py: ---------- from . import Slave Slave.main() I have added the first line #!/usr/local/bin/python3.0 manually Slave.py: --------- def main() : print("Hello World") Now, when I invoke Master.py I get Traceback (most recent call last): File "Master.py", line 2, in <module> from . import Slave ValueError: Attempted relative import in non-package thanks for looking into it, Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany -- http://mail.python.org/mailman/listinfo/python-list
