Subsets() with same element multiple times?
Essentially, I want to use:
ListA = [1,2,3]
S = some_function(ListA, 2)
list(S)
And receive in return
[[1,1], [1,2], [1,3], [2,2], [2,3], [3,3]]
Theoretically, some_function()
ought to be Subsets()
with some options, but that doesn't seem available. Is there a good way to do this other than a multiple for loop? You can work around how Subsets()
works with:
ListB = []
for i in ListA:
for j in ListA:
A = sorted([i,j])
if A not in ListB:
ListB.append(A)
sorted(ListB)
But that gets tedious (and probably time-consuming) when you want 6-element subsets--and extra annoying if you want to be able to change the length with a variable. It seems like this ought to be an included functionality; what some_function()
am I missing?
