Hi! Once you've written a solution (as in the example of calculating the body mass index) and wrapped the calculation code in a function, you can call that function with a single line, simply passing in new values.

Code written as a function is convenient to use in a large program in different parts of it, which simplifies the program itself and reduces the number of lines of code. For example, think about the console output function /print()/. You don't need to write it every time in your program to output something to the console. You simply call this function by its name, and everything else happens "under the hood." This code functionality was once written by a programmer and saved as a function, and it is also integrated into the Python programming environment.
