Putting it All Together

In this section, we are going to level up what we can do with functions!

So far, you have practiced writing functions with different kinds of inputs, outputs, and default values, but now we will to explore ways of building more complex $($but still compartmentalized and transferable$)$ code by combining functions.

One particularly useful way to build more complex code is to have functions that call other functions inside them.

When we call a function inside another function, remember to keep in mind variable scope. Any variables the function you are calling inside another function needs will need to be provided as input arguments in your outer function!

In the cell below, write a function that combines your concatenate$\_$strings and check$\_$f$$r$\_$strings functions to:

Take in $3$ values

Check if those $3$ values are strings

If all three are strings, concatenate those strings into one new string

Return the new concatenated string
