Solve the following python programming problem given the following code:
# Earlier in the tutorial, we covered the print function. Print the String "Hello, world!"

# We also covered the type function. Find the type of the String "Hello, world!"

# Daisy-chaining functions in that manner is extremely useful when working with data.

# We can also define our own functions. Here, I've written a simple 3-number added

def ThreeNumberAdder (n1, n2, n3):
    return n1 + n2 + n3

# And now I can test it out:
print(ThreeNumberAdder(1, 2, 3))

# Copy that function below, and see if you can modify it to multiply 3 numbers instead.


# You can test your ThreeNumberMultiplier below here.

Given the above code, generate some markdown instructions for it.

#Here is Python code to find the type of the String "Hello, world!"

Functions
Functions are pieces of code that are "saved" and can be re-run whenever you need to. They help to organize your code so that you don't have to re-write the same thing over and over again. They can also be used for some advanced techniques such as recursion. You can create a function using the def keyword. You may also see the lambda keyword used to create small one-line functions.
When you use a function in your code, we say that you call the function. To call a function, place a pair of parentheses after the function name. Functions can take values as input. Those values are called parameters, or arguments. When you provide a value to the function, we say that you pass a value to the function. In general, functions are only allowed to work with data that are passed in. To pass a parameter into a function, place it in the parentheses. There are rules surrounding what values you can pass and when, but it's easiest to learn these rules by imitating other peoples' code.
