一.将一个列表,分成若干个大小为n的列表
def split_list_average_n(origin_list, n):
for i in range(0, len(origin_list), n):
yield origin_list[i:i + n]
测试:
a = ["a", "b", "c", "d", "e", "f", "g"]
b = split_list_average_n(a, 4)
for i in b:
print(i)
输出:
['a', 'b', 'c', 'd'] ['e', 'f', 'g']
二.将一个列表,分成n个大小均分的列表
def split_list_n_list(origin_list, n):
if len(origin_list) % n == 0:
cnt = len(origin_list) // n
else:
cnt = len(origin_list) // n + 1
for i in range(0, n):
yield origin_list[i*cnt:(i+1)*cnt]
测试:
a = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l"]
b = split_list_n_list(a, 4)
for i in b:
print(i)
输出:
['a', 'b', 'c'] ['d', 'e', 'f'] ['g', 'h', 'i'] ['j', 'k', 'l']
