Hmm, I like this better:
>>> all([len(alpha)==1, len(beta)==1, len(beta2)==1, len(alpha_stdfehler)==1])
True
But you're right, lambdas rock:
>>> all([filter(lambda arg: len(arg)==1, [alpha, beta, beta2,
alpha_stdfehler])])
True
Cheers!!

All right, but apart from the sanitation, the medicine, education, wine, public
order, irrigation, roads, a fresh water system, and public health, what have the
Romans ever done for us?

Probably a bit too much, but I just like map & lambda functions:
Assuming the vars are strings:
alpha = 't'
beta = 'e'
beta2 = 's'
alpha_stdfehler = 't'
aList = [alpha, beta, beta2, alpha_stdfehler]
allOneLenght = sum(list(map(lambda x: len(x) == 1, aList))) == len(aList)
if allOneLenght:
Hope this help (but I doubt that...),
