Task Manager

A Python program that manages tasks and the users assigned to each task.

Description

This program is for for a small business that allows it to track, edit and report on tasks assigned to each member of the team.

Once logged in, a menu is presented to the 'admin' while a limited menu is presented to any other 'user'.

From the user menu, all users are able to:

• Add a new task given the input of the assigned user, task title, task description, due date, completion status and date assigned.
• View all tasks in the database.
• View tasks assigned to them and then either:
  • Mark the task as complete or,
  • Change who the task is assigned to or the due date of the task.

From the admin menu, an admin has extended permissions to:

• Register and validate a new user given the input of a username and password.
• Generate a user and task report.
• Display user and task statistics.

Each menu option calls the corresponding function for action. Any time a task or user is edited the details are updated in the following txt files.

The program works with two input files:

• A user.txt file that stores the username and password of each team member, per line.
• A tasks.txt file that stores a list of all the tasks that the team is working on, per line, which includes:
  • The username of the person to whom the task is assigned.
  • The title of the task.
  • A description of the task.
  • The date that the task was assigned to the user.
  • The due date for the task.
  • Either a ‘Yes’ or ‘No’ value specifying if the task has been completed.

The program generates two output files:

• A user_overview.txt file that displays a report of the team members statistics, per line, which includes:
  • Total number of registered users.
  • Total number of tasks that have been generated and tracked.
  • Total tasks assigned per user.
  • Percentage of total tasks assigned per user.
  • Percentage of completed tasks assigned per user.
  • Percentage of incompleted tasks assigned per user.
  • Percentage of incompleted and overdue tasks assigned per user.
• A tasks_overview.txt file that displays a report of the tasks statistics, per line, which includes:
  • Total number of tasks that have been generated and tracked.
  • Total number of completed tasks.
  • Total number of incomplete tasks.
  • Total number of incomplete and overdue task.
  • Percentage of incomplete tasks.
  • Percentage of overdue tasks.

Functionality summary:

• User login
• Register a new user
• Add a new task
• View all tasks
• View and edit a users tasks
• Generate user and task reports
• View user and task statistics

Programming principles
