I need help forming a code for these questions using Python. My codes don't seem to be working.

1. Write a while loop that lets the user enter a number. The number should be muliplied by 10, and the result assigned to a variable named product. The loop should iterate as long as product is less than 100. 2. Write a while loop that asks the user to enter two numbers, The numbers should be added and the sum displayed. The loop should ask the user if he or she wishes to per- form the operation again. If so, the loop should repeat, otherwise it should terminate. 3. Write a for loop that displays the following set of numbers 0, 10, 20, 30, 40, 50 . . 1000
