Python is a versatile language, and even beginners can design and implement something cool with only basic knowledge.

Basic Python Concepts

By now, you should knowwhat Python isand how it works.

User Input and Output

User Input and output are the core of our app.

Lists are just collections of other data types.

To keep things simple, we’re just using words (strings) to define our tasks.

Were going to use a list of strings to keep track of those tasks.

The confirmation is necessary because it informs us that the function is working.

Thats also pretty simple since lists are so powerful.

If it finds the task, itll remove it.

What happens if the task is spelled wrong or just doesnt exist?

The first line, if tasks: asks Python to peek if the tasks list is empty.

If it isnt, well loop through it using a for loop.

For loops have a defined starting and ending point.

In this example, well enumerate the tasks list to get the number of tasks in the list.

Then, well loop through each entry and print it to the screen.

If the list is empty, well just tell the user that their to-do list is empty.

In any code, testing is crucial to ensure our code does what we want it to do.

Suppose the user enters A to add a task.

If they choose D, the program displays the list of their tasks.

This main function will continue to run indefinitely because we encapsulate it inside of a while loop.

Finally, the bottom line will start the main() function when we tell the program to run.

Congratulations on completing your first fully functional Python to-do list!

Where to Go From Here

As youve probably noticed, the interface for this system is minimal.

It looks boring with a terminal or console entry.

Each of these can help you learn Python programming a bit more by exploring more complex concepts.

Thats the joy in codingyou can take a simple idea and turn it into something that suits you perfectly.
