python列表对应元素相乘_在python中,将两个列表中的每个元素相乘

时间:2025-03-28 12:39:07

我的任务是仅使用基本的python函数(而不是numpy)生成以下列表。以下是我所有的代码:# a list which contains i^2 with i = 1 through 5

squares = [pow(i,2) for i in range(1,6)]

#print squares

#2. Create a list which contains log[j] with j = 1 through 5

logs = map(math.log10,range(1,6))

#print logs

#3. Create a list which contains [i_1*j_1, i_2*j_2, i_3,j_3...]

def mult(x,y): return x*y

lmultl = map(mult,squares,logs)

#print lmultl

#4 Create a list which contains [[i_1*j_1, i_1*j_2, i_1*j_3...][i_2*j_1, i_2*j_2, i_2*j_3...]etc]

logslol = [[logs]*5] #Returns a list of lists with 5 copies of list "logs"

def lrep(x): return [x,x,x,x,x] #Returns a list w/ 5 copies of each integer

squareslol= map(lrep,squares) #Returns list of lists "for squares"

print map(mult,logslol,squareslol) #Attempt 1 to create goal list

print [logslol*item for item in squareslol] #Attempt 2 to create goal list

我的问题是针对list“4”中的最后一个print语句:我得到了一个TypeError:“cannot multiply sequence by non int of type'list'”对于这两个方法。有没有更有效的方法将每个元素乘以两个“列表列表”?在
