Powerset function alternative does not work

[oClaerbout]

Hi, I'm new to python (and to coding in general) and I need a powerset function. The one just below works fine, but I'm not familiar with the following notition:

1	newset = [subset + [x] for subset in result]

I try to replace it with the following code:

1 2	for subset in result: newset = [subset + [x]]

This however seems to generate an error. Can anyone please explain to me why this is the case? Thank you!

Full code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

def powerset(xs):     result = [[]]     for x in xs:            newset = [subset + [x] for subset in result]         result.extend(newset)     return result   print(powerset([0,1,2]))   def powerset2(xs):     result = [[]]     for x in xs:            for subset in result:             newset = [subset + [x]]             result.extend(newset)     return result   #data = build_items(3) print(powerset2([0,1,2]))

your second bit of code isn't indented properly
