The idea for this basic script is to emulate my physical pen-and-paper To-Do list by creating a command-line script that can create, store, and edit a To-Do list from the command-line.

• Ability to create a To-Do list which includes the following:
  • Date/Day
  • List of items
• Be able to add items to an existing To-Do list.
• Be able to cross off items on an existing list to signify task has been completed ([x])
• Saves lists in a folder called ToDoLists with following naming structure : "<date>_ToDoList.txt"

The point of building this script is mostly to help me learn more about the Argparse module and file handling in Python. I will likely build on the base features further in the future with the more I learn.

Works on both Windows (e.g Anaconda Prompt) and Linux terminals.
This script uses Python 3, and also requires the colorama module to be installed.
Colorama can be installed using sudo pip install colorama.

python3 todo.py [-h] [-n | -e | -v | -a | -m]

optional arguments:
  -h, --help  show this help message and exit
  -n, --new   Create a new To-Do list.
  -e, --edit  Edit an existing To-Do list
  -v, --view  View todays To-Do List
  -a, --add   Add task to today's list
  -m, --mark  Mark off task from today's list

Builds a folder of To-Do Lists in the directory this script is stored in.

• argparse - Used for writing the command-line interface.
• datetime - For retrieving date/time information.
• os - Used for creating, reading, and writing files. os also allows you to manipulate paths and file structures regardless of the operating system you are using to run the script.
• colorama - Used for outputting coloured text to the terminal.
• webbrowser - Used for opening text files with Notepad/Gedit when editing.
