是否可以通过列表理解来执行以下操作？尝试存储在循环中任何给定点看到的最大值。
def test(input):
a = input[0]
b = []
for i in input:
a = max(i,a)
b.append(a)
return b
print test([-5,6,19,4,5,20,1,30])
# returns [-5, 6, 19, 19, 19, 20, 20, 30]
请您参考如下方法:
您可以使用 itertools.accumulate与 max内置于 Python 3:
from itertools import accumulate
lst = [-5,6,19,4,5,20,1,30]
r = list(accumulate(lst, max)) #[i for i in accumulate(lst, max)]
print(r)
# [-5, 6, 19, 19, 19, 20, 20, 30]
