You are asking to develop a "Converting decimal to Binary or hexadecimal" program in Python. The program tell user it can convert any decimal number range 0 to 15 to corresponding binary number or hexadecimal number. 1. Use a function to get an integer between 0 to 15 (assume O is an integer) from the user. For any incorrect input, display a reminding message and let user re-enter. 2. Use a function to get the user's choice, "a" or "b", from a menu: a: Converting to Binary b: Converting to hexadecimal 3. Convert and display the number according user's choice in function main(). 4. Ask user if want to convert another decimal number. If "Yes", repeat steps 1 to 4 above. If "No", terminates the program. How to get higher score for this assignment: 1. The program must have at least 3 functions including function main(). 2. For any wrong input, tell the player what is wrong and asking to re-enter. 3. Allow a user to play multiple times. For example, using a while Remind the player what input to stop the game. 4. Formatting your outputs and developing your program a user-friendly one. 5. Document your program by adding comments: 1. Introduce/describe the program including the author, date, goal/purpose of the program at the very beginning. 2. Document every variable/function used at the program even the name is meaningful 3. Explain/comment operation/activity/logic of your code. For example, "Checking whether the input is integer from 0 to 15". 6. Testing your program for all possible inputs. Make sure it runs right and will not get syntax/running error.
