1> What is the significance of 1000 in this code ?
2> Can you combine lines 8, 10 and 11 into a single statement ? [ and thus eliminate the use of "new_value" ]
3> Can you combine the code to calculate fibonacci numbers and finding the first 12 even numbers into a single loop ?
4> The output of the "for" loop in line 20, 21 is in a single line. Can you update the code to print a new line character after the last number is printed ?
