我正在这样做,但感觉这可以用更少的代码来实现。毕竟是 Python。从一个列表开始,我根据字符串前缀将该列表拆分为子集。
# Splitting a list into subsets
# expected outcome:
# [['sub_0_a', 'sub_0_b'], ['sub_1_a', 'sub_1_b']]
mylist = ['sub_0_a', 'sub_0_b', 'sub_1_a', 'sub_1_b']
def func(l, newlist=[], index=0):
newlist.append([i for i in l if i.startswith('sub_%s' % index)])
# create a new list without the items in newlist
l = [i for i in l if i not in newlist[index]]
if len(l):
index += 1
func(l, newlist, index)
func(mylist)
