Testing schedule

This a problem set for you to work through ^[1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

to build your skill applying computational thinking to a problem
to assess your knowledge and skills of different programming practices

What is this problem set trying to do[edit]

Our goals are to solve a real-world problem. We will need to use file operations, iteration, selection, and the python datetime library.

The Problem[edit]

Construct a python program which speaks the time and a students name 3 minutes before their appointment. The lists of times and students are included on this page as a plain text file.

You will need this file to complete this problem set.

For example, Ben might have an appointment at 9:45. At 9:42 I should hear "Ben has an appointment in 3 minutes and should now go to the testing center" from your computer speakers.

Good luck. This is very real-world type of problem.

How you will be assessed[edit]

Your solution will be graded using the following axis:

Scope

To what extent does your code implement the features required by our specification?
To what extent is there evidence of effort?

Correctness

To what extent did your code meet specifications?
To what extent did your code meet unit tests?
To what extent is your code free of bugs?

Design

To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
To what extent is your code eliminating repetition?
To what extent is your code using functions appropriately?

Style

To what extent is your code readable?
To what extent is your code commented?
To what extent are your variables well named?
To what extent do you adhere to style guide?

import os
from datetime import datetime, timedelta

timeList = []
prevIndex = 0
found = False

file = (open("/FULL_PATH_TO_FILE_HERE/testing_schedule.txt", "r")).read()
classList = file.split(' ')

for i in classList:
    if ':' in i:
        index = classList.index(i)
        timeList.append((classList[prevIndex:index]))
        prevIndex = index

timeList = timeList[1:]

for i in range(0,3):
    for i in timeList:
        if len(i) != 3:
            timeList.remove(i)

def sayNames(timeList, currentTime):
        for i in timeList:
            if i[0] == currentTime:
                os.system("say '{} and {} have testing in 3 minutes.'".format(i[1], i[2]))
                return True

while True:
    if found == True:
        break
    now = datetime.now() + timedelta(minutes=3)
    currentTime = now.strftime("%H:%M:%S")
    found = sayNames(timeList, currentTime)
