Newbie question: Tab key giving different output

[getkaizer at gmail.com]

Hello,
I'm a newbie to python. I run python under Manddrake Linux 10.2 from a
terminal.

While in the interactive mode, i need to use the tab key to indent my
code. However, i get a message "List all 174 possibilities? (Y/N)"
instead of an indent. So i use spaces.

How do i tell python to give me indents?

Thanks in advance!

Have a great day,
Kaizer.
