So this is my try to implement Euclidean algorithm. I don't understand why it's returning None on last iteration

Answer 1

Thanks Ę ~ J It helped. So basically i just had to add return to function call in else statement

Answer 2

Ę ~ J still returning None without this line

Answer 3

Ę ~ J if i call the the function without print() then there will be no output as well

Answer 4

Ę ~ J this algorithm must return 80 at the end, last iteration don't work i don't know why

Answer 5

Ę ~ J Last call of function will be like this
eucl(160, 80)
In this case the if statement is matched, and must return 80, but it's returning None
