COMP10200 Assignment 1, part a Solution

Overview
This assignment will get you using Python lists and sets along with related arrays in numpy. Try to keep your solution short – after all the user input is done, you should not need more than about 15 to 20 lines of code (not including blank lines and comments) to do the processing and output. Pay attention to the detailed instructions below and make sure you cover everything.
Input
Get a list of player names from the user. Let the user decide how many players there should be. Don’t let the user enter duplicate or empty names. Use string methods to strip leading and trailing whitespace and to make sure each name is capitalized. Make sure your code is efficient (use a set). At the end of the process, the names should be stored in a new random order in a numpy array.
Related Arrays
Now see how quickly the users can hammer on the Enter key. Use the input function to get a bunch of inputs from each user. Use the Python time function in the time module to compute the interval between each input. Intervals should be rounded to 3 decimal places. Let the user decide how many time intervals there should be.
Below is an example of a piece of code that computes the time (without rounding) for a single interval. You’ll have to adapt this for your own code.
import time input() time1 = time.time() input() time2 = time.time() print(time2-time1,"seconds")
You can use any data structures you like during the process of collecting times, but at the end you should convert the data so that it is stored in a two-dimensional numpy array with each row containing the corresponding user’s times. This array is related (parallel) to the names array. Now sort the two parallel arrays so that they are both in alphabetical order by player name. Use numpy methods for this.
Output
Using numpy (no loops) compute and output the mean time for each player (rounded to 3 decimal places) then report the fastest and slowest mean times (rounded to 3 decimal places) as well as the fastest and slowest single interval times (rounded to 3 decimal places). Include the names of the players who achieved these times.
Finally, you should output both the names and the times array for debugging.

Example Run
How many players? 5
How many time intervals? 9

Enter 5 player names

Name can't be empty
Khadija Lee
lee Notice that leading and trailing
Name already entered
Lee spaces as well as capitalization Name already entered is ignored.
LEE
Name already entered alicia lachlan Margie

Lee's turn. Press enter 10 times quickly.

Khadija's turn. Press enter 10 times quickly. The playing order is random.
(10 blank lines) Names are capitalized.
Lachlan's turn. Press enter 10 times quickly.
