python multiply all elements except ith element in list and return list

Question

Suppose I have a list .I want to multiply its all elements except with the i'th element.

Example:

• input: [1,2,3,4]
• output: [24,12,8,6]

Here, the output

 24 is 2*3*4
 12 is 1*3*4
 8 is 1*2*4
 6 is 1*2*3

Any help would be appreciated

Answer 1

A simple solution using two for loops:

l=[1,2,3,4]
out=[]
for i in range(len(l)):
    prod=1 
    for j in range(len(l)):
        if(j!=i): #Iterate through list once more and compare the indices
            prod=prod*l[j]
    out.append(prod) 
print(out)

Output is: [24, 12, 8, 6]
