Because the expressions you typed in is a reference to the function, not a
call of it. A call would be as follows:

    mytest.yo()

Remember, Python is neither Perl nor VBScript, and because it makes just as
much sense for program to deal with functions as it does for them to deal
with character strings, you have to be able to both refer to and call
functions. It's quite legal to say this:

    ff = mytest.yo
    ff()

and this, too, should print "Bla".

I presume you mean that you replaced the print statement in the function
with a return?

For the same reason :-)
