Question

What will be displayed after the following code is executed? for num in range(0, 20, 5): num += num print(num)

Answer 1

The code will display the value 30, which is the result of the last iteration in the loop where the value 15 is doubled.

Step-by-step explanation:

When the code provided is executed, the last value stored in the variable num will be displayed because the print statement is placed outside of the loop. The range function generates a sequence of numbers from 0 to 15 in steps of 5, resulting in the numbers 0, 5, 10, and 15.

Inside the for loop, num is doubled each time (num += num). However, since the print statement is not within the scope of the loop, it will print only the final value of num, which is the result of the last iteration where num is 15, after being doubled to 30.
