In Python, we define a new procedure or function with the keyword def. To use def, we also need to specify: a name for the procedure, a list of its inputs, and the instructions the procedure will perform in this format:

Procedures, also known as subroutines or methods, are blocks of code that perform a specific task without returning a value. They can accept input parameters and modify the values of variables. Procedures are typically used to group related code together and make the program more organized and modular.

There are two types of subroutines: procedures and functions. A procedure just executes commands, such as printing something a certain number of times. A function produces information by receiving data from the main program and returning a value to the main program.

In Python, the fundamental abstraction of a computation is as a procedure (other books call them "functions" instead; we'll end up using both terms). A procedure that takes a number as an argument and returns the argument value plus 1 is defined as: def f(x): return x + 1 The indentation is important here, too.

Define a procedure, find_second, that takes two strings as its inputs: a search string and a target string. It should output a number located at the second occurrence of the target string within the search string.
