Explain the result

Question

f=[1, 2, 4, 6, 8]
print (str(f [2] - f [4] % 3) * 3)

Answer 1

Владислав Китаев
f[2] the third element of list which is f[2] = 4
f[4] fifth element of list which is f[5] = 8
str() convert all things in string format. So
str(4-8%3) => str(4-2) => str(2)
Where: 8%3 is returning remainder which is 2
str(2)*3 any string multiplication with integer will repeat the number of times so here it's 3 so 3 Time string 2 is printed which is "222" so output printed as 222.

Answer 2

Here's an explanation, step by step. The first thing we're going to do is get the values of f[2] and f[4]. f[2] is equal to 4, and f[4] is equal to 8. Now, the expression to calculate looks like this:
str(4 - 8 % 3) * 3
According to the order of operations, we should calculate the modular value of 8 by 3 first, which returns 2 as that is the remainder after dividing 8 by 3. Then, we can subtract 2 from 4. Now, the expression looks like this:
str(2) * 3
Now we convert 2 to a string, and multiply it by 3. This returns "222" because when multiplying a string by a integer, we'll get the same string repeated integer times.
Therefore, the result is "222".
