comparing multiple values

[Skaperen]

i have several variables that at one point i expect them all to have the same value and need to test it:

   ...
   if a==b and b==c and c==d and d==e and e==f and f==g and g==h:
        print('they are all the same')
    else:
        print('it did not work')

is there a better way to test if they are all alike?  i can set it up so they are all in a list or tuple making up the whole sequence.  i'm thinking maybe sorting a list and comparing first to last.
