python - Split list of tuples based on value within tuple

Question

If I have the following:

[(1,2),(2,3),(0,0),(4,0),(0,1),(3,9),(2,0),(2,4)]

How can I split it into:

[(1,2),(2,3)], [(0,1),(3,9)], [(2,4),]

were every time I see a tuple with a 0 at index 1, e.g. (1,0), I split the list.

Answer 1

特に滑らかではありませんが、次のようにループすることができます。

myList = [(1,2),(2,3),(0,0),(4,0),(0,1),(3,9),(2,0),(2,4)]
groupedList = []
subList = []
for tup in myList:
    if tup[1] == 0:
        if subList != []:
            groupedList.append(subList)
            subList = []
    else:
        subList.append(tup)
if subList != []:
    groupedList.append(subList)
print groupedList

出力：

[[(1, 2), (2, 3)], [(0, 1), (3, 9)], [(2, 4)]]
