So, I'm going to re-size this window, and run the module.
Then we'll just re-size this, and will copy and paste these function calls.
So the first function call should result in 6.0 and it does.
And the second example should give us something like what we had
there, and in fact it's giving us more digits.
I'm going to use that result here instead.
So that's what we expect to get.
It's not only Python's modules that we can import.
We can also import a module that we wrote.
For example, if we wanted to use one of
our triangle functions in another module, we could import triangle.
The module being imported should be in the same directory as the module
that's importing it.
