Basically, for each setting of a, you must do each possible b,
and for each a,b setting you must do each possible c, etc.

for a in [True,False]:
for b in [True,False]:
for c in [1,2,3,4]:
print 'combined settings:',a,'\t',b,'\t',c
combined settings: True True 1
combined settings: True True 2
combined settings: True True 3
combined settings: True True 4
combined settings: True False 1
combined settings: True False 2
combined settings: True False 3
combined settings: True False 4
combined settings: False True 1
combined settings: False True 2
combined settings: False True 3
combined settings: False True 4
combined settings: False False 1
combined settings: False False 2
combined settings: False False 3
combined settings: False False 4
