Because that's what you programmed it to do.
Almost. If you enter 1 or 10 you won't get an error.

Look at your logic:

> while number < 1 or number > 10:
>        print 'Please enter a number between 1 and 10'

If the first number you enter is say 7.
It skips the first while loop and asks for another number.
If you enter 7 again
It then goes into the second while loop and reports an error.

The only numbers which don't fall into one of the two loops
are 1 and 10.

BTW It's bad practice to use input() in Python v2 becauise it has 
security issues. Instead use raw_input() and convert to an
int() or float() explicitly.

There is a bug here too since you don't provide a way
for the user to enter a new number. It will loop forever.
