Suppose you want to select all possible combinations a,b,c,d to from
the range [1,2,3,4] , but a,b,c,d should be unique (thus not equal).
The following approach seems clumsy:
for a in range(1,5):
for b in range(1,5):
for c in range(1,5):
for d in range(1,5):
if a<>b<>c<>d:
print a,b,c,d
Is there a smarter way? Thanks in advance!
