We've seen that Python has several

mathematical operators, like multiplication and subtraction, and

we know that the mathematical operation

multiplication is associated with an asterisk symbol.

There are lots of other operations that we might want to do,

with or without math, and not enough meaningful symbols to go around.

So, for example, we may want to figure out, which of several

numbers is the largest one, and there's no symbol associated with that operation.

Instead, Python has a set of built of

functions that allows, allows us to perform these operations.

So take a look at those now.

So let's start with that example that I mentioned, which

is to find out which of several numbers is the largest.

The Python built in function that we'll use for that is the Max function.

So, the name of the function is Max. I use an open parenthesis.

And notice the yellow pop up box. That's

[INAUDIBLE]

help that is intended to remind

professional Python programmers what the function does.

And you probably won't understand it yet.

And that's to be expected.

And then I provide the arguments to function, so

in this case, I'm going to provide two arguments.

Pass two arguments to the function.

The arguments values are 36.7 and 23.4, so this is function call.

With arguments 36.7 and 23.4. When I hit Enter, Python will evaluate

that function call, and tell me that 36.7 is the bigger of the two numbers.
