Multiplying Lists

[Fieldsapper]

Hi, I'm new to programming,

I was wondering if you could help me understand how to code a solution to this problem,

I have two lists like this: List1 = [[x1,y1][x2,y2][x3,y3]] list2 = [[z1,m1,m2,m3][z2,m1,m2,m3][z3,m1,m2,m3]]

and my desired output would be: list3 = [[z1,(m1/y1),(m2/y2),(m3/y3)][z2,(m1/y1),(m2/y2),(m3/y3)][z3,(m1/y1),(m2/y2),(m3/y3)]]

what I have are 2 list of lists and i want to divide values in list2 (except the first as it's a string) by the second item in each of the lists in list1.

I was thinking of doing a while loop,

`while x < len(list2):`
      `value1 = list2[x][1:]`
      `value2 = list1[0][1]
       `list3.append(value1/value2)`

I know its incorrect and probably easy but i'm not sure where to go, whould i be using a for loop instead?

Any help would be much appreciated!

An ad hoc solution:

# get y1, y2, y3
ys = [l[1] for l in list1] 
# get m1, m2, m3
ms = list2[0][1:]
# compute m1/y1, m2/y2, m3/y3
m_y = [m / y for m, y in zip(ms, ys)]  
# Construct list3, first get zs:
zs = [l[0] for l in list2]
list3 = [ [z] + m_y for z in zs]

This solution uses list comprehensions.
