You're running Python 2.3 on a windows os.

you're assigning the value 3 to the name 'None'

the compiler warns you that 'None' is a special name that you probably
don't want to rebind.

> >>> False = 4

you assign the value 4 to the name 'False'

> >>> True = 5

you assign the value 5 to the name 'True'

> (3, 4, 5)

The interpreter prints the value of the tuple you entered.

Which part of this didn't you understand? (my mind-reading skills are
too rusty to determine if you think this shouldn't happen for some
reason...)
