python list乘以每个值

Question

我想知道如何将两个不同列表中的每个元素相乘。

例如：

list_a = [1,2,3,4,5] list_b = [10,20,30,40,50]

我想让它1X10 2X20 3X30 4X40 5X50

，这样的结果将是10, 40, 90, 160, 250

我真的很感激，如果你能帮助我。

Answer 1

a = [1,2,3,4,5] 
b = [10,20,30,40,50] 
print [a[i]*b[i] for i in range(len(b))] 

这将有助于您

Answer 2

一个清洁的版本是：

a,b = [1,2,3,4,5],[10,20,30,40,50] 
for i,j in zip(a,b): 
    print '%d x %d = '%(i,j),'%d units'% ((i*j)) 

Answer 3

您可以如下使用zip功能。

>>> list_a = [1,2,3,4,5] 
>>> list_b = [10,20,30,40,50] 
>>> [(x[0]*x[1]) for x in zip(list_a,list_b)] 
[10, 40, 90, 160, 250] 

Answer 4

a = [1,2,3,4,5] 
b = [i*i*10 for i in a] 

Answer 5

使用zip()：

list_a = [1,2,3,4,5] 
list_b = [10,20,30,40,50] 
final = [k*v for k, v in zip(list_a, list_b)] 
print final 

输出：

[10, 40, 90, 160, 250]
