将二维列表乘以一维列表到每个元素

Multiplying 2D list by 1D list to each elements

我想将一维列表与二维列表的元素相乘。我怎样才能用列表理解来做到这一点?

a = [1,2]
b = [[3,4],[5,6]]

想要的结果是

c = [[3,8],[5,12]

我试过这种方法

c = [i*j for i, j in zip(a,b)]

我遇到的错误是

TypeError: can't multiply sequence by non-int of type 'list'

您可以使用嵌套列表理解:

c = [ [x * y for x, y in zip(a, row)] for row in b ]
