The set of values in elements[0] is {0,1,2}
I want the set of max values in elements[1]: {11,41,12}
Do they have to be IN THAT ORDER?
Yes.
Sets aren't ordered, which is why I gave my answer as a list. A wrongly
ordered list, but I thought it rude to point out my own error, as no one
else had. :-)
Assuming you want numeric order of element[0], rather than first
occurrence order of the element[0] in the original tuple list. In this
example, they are both the same.
Here is a corrected version
from collections import OrderedDict
def build_max_dict( tups):
dict = OrderedDict()
for (a,b) in tups:
if (a in dict):
if (b>dict[a]):
dict[a]=b
else:
dict[a]=b
return(dict.values())
This solution giving the answer as type odict_values. I'm not quite sure
what this type is, but it seems to be a sequence/iterable/enumerable
type, whatever the word is in Python.
Caveat: I know very little about Python.
