Hey, welcome to a brand new day.
Yesterday, you learned how to create arguments for your defined functions.
You learn that you can have one argument such as here or more arguments divided by commas.
So at this point, our program is able to get to dos by calling this function throughout the script,
such as here, getting the to dos in the list through that function.
But also the program is able to write to do in the text file in the to dos that text file using this
right to this function.
So function with one argument, function with two arguments.
And another difference between these two functions is that this function here returns something and
this function here doesn't return a value.
So some functions output something and others simply do some actions when you call them.
And that's all.
For example, this function here writes the two dos in a text file, and that's all.
It doesn't return anything.
Today we're going to be looking deeper into functions.
You're going to learn about default arguments.
So ready?
Let's see you in the next video.
