Aceptable Password VI

Hi, in the mission of the title we got the following rules for the verification:

The verification conditions are:

• the length should be bigger than 6
• should contain at least one digit, but it cannot consist of just digits;
• having numbers or containing just numbers does not apply to the password longer than 9.
• a string should not contain the word "password" in any case;
• should contain at least 3 different letters (or digits) even if it is longer than 10

So why this test have to be false? Its length its 7 and got 1 digit:

• assert isacceptablepassword("aaaaaa1") == False

thank you
