计算python列表中所有数字的所有产品

Question

假设我有这个列表:

[2,3,5,7] 

我想输出所有乘法组合:

[6,10,14,15,21,35,30,42,105,210]

在python中有一个内衬吗？

Answer 1

假设你在输出中忘记了70 ...

用numpy.prod和itertools.combinations:

>>> from numpy import prod
>>> from itertools import combinations
>>> lst = [2,3,5,7]
>>> [prod(x) for i in range(2, len(lst)+1) for x in combinations(lst, i)]
[6, 10, 14, 15, 21, 35, 30, 42, 70, 105, 210]
