Answer 2

You could use a for- instead of a while-loop

Answer 3

You can check It with a condition:

if i%2 == 0:
print("It is multiplicable to two")
else:
print("Isn't multiplicable to two")

Or for more especific:

for i in range(0,num):
if i%2 == 0:
print("It is multiplicable to two")
else:
print("Isn't multiplicable to two")

Answer 4

Jairo Soto I think not, because the i is increasing and while It, We are moduling him by 2

So, Just think:

1/2 = 1 (It is not multiplicaple)
2/2 = 0 (It is multiplicaple)
...

It is just my logic 😅

Answer 5

Jairo Soto Yes, but in this code, you canal only see a number (It is helpful sometimes) but you cannot define num's value by yourself

Answer 6

Puesto que tiende más a un problema matemático, supongo que mediante algoritmos de factorización.

Answer 7

Usa el bucle for y el module "%"

Answer 8

Cat do Chrome I think that "if num % i == 0" is better for this case. what do you think?
