Go inside another For

Question

Guys I’m needing to run a for inside another for but I’m not getting it. I need to store the result value within a variable. I’m not familiar with python, I believe this is the biggest problem. Follow what I’ve been trying to store the result.

import math

perimeter = [18, 24, 14]

area = [24, 36, 10]

lista2 = []

for i in perimeter:
    for x in area:
        d = {}   
        d = print(((i/2)+math.sqrt((i/2))**2-4*x))/2))
        lista2.append = (d)
print(lista2)

Can anyone propose me a solution to the problem? Because I can’t reach the result.

Answer 1

1. I do not know if it was a mistake in the formulation of the question, but the code is undefined. In the Python language, what defines what is inside a code structure, such as for, is its internal indentation.

2. The function append, for lists, you receive a value that will be added to the list. The way it’s being used, it’s like you’re passing its return value to the variable d, which makes no sense, since it returns nothing. The correct use would be as follows:

   Lista2.append(d)

3. There is a syntax error in the variable calculation d. Correction, it is as follows:

   d = ((i/2)+math.sqrt((i/2))**2-4*x)/2

The whole code goes like this:

import math

perimeter = [18, 24, 14]

area = [24, 36, 10]

lista2 = []

for i in perimeter:
    for x in area:
    
        d = {}
    
        d = ((i/2)+math.sqrt((i/2))**2-4*x)/2
    
        lista2.append(d)

print(lista2)
