Where are you getting this? Is it a Python traceback? If so, please copy and
paste the entire traceback, starting with the line:


and ending with the last of the error message.

Where are you typing pyraf? In the Python interpreter or the operating
system shell? Is the prompt >>> or $ or something else?

Are you using the default Python interactive interpreter, IDLE, or some
third party IDE?

Please explain how you launch Python, e.g.:

"I double-click on the Python icon on the desktop"

"I open a terminal, and enter python at the shell prompt"

Or something else?

What version of Python are you using? What operating system?

What happens if you run this at the bash prompt?

Do you see the path to pyraf in Python's path? (Python does not use the same
