[Tutor] Python strings example

[Ankit Gupta]

In 2nd example you return will look something like this "return False and
True" which will result in False as AND operation will only return TRUE if
both value is TRUE.
as I can understand you want to return TRUE if sentence contain at least
one character or at least one digit or both. Therefore I will suggest to
use OR instead of AND operation.
