Outlines
đ Introduction to Super Carol and APIs
This paragraph introduces the concept of Super Carol, an evolved version of Carol, a dog character used in programming examples. It highlights that Super Carol can learn new moves and comes with built-in commands like 'turn right' and 'turn around', which were previously undefined. The paragraph also explains the concept of an API (Application Programming Interface), describing it as a set of tools for building software. The speaker reveals that the audience has been using Python, a professional programming language, all along. The paragraph concludes by introducing the Karel API, which simplifies the process of making Carol move across the screen, and the Super Karel API, which includes additional commands.
đ Using Super Carol in Programming and Documentation
The second paragraph delves into the practical application of Super Carol in programming. It discusses the removal of the need to define 'turn right' commands due to Super Carol's built-in capabilities. The speaker demonstrates how Carol now makes a right turn instead of turning left three times, showcasing the ease of use with the new API. The paragraph also emphasizes the importance of API documentation, which provides crucial information on how to use the API properly. The documentation is available in the 'docs' tab and includes syntax and usage examples. The speaker suggests revisiting a previous program involving hurdles to illustrate the updated process with Super Carol.

Transcripts
hi in this video we'll introduce super
Carol we've been using Carol in all of
our programs and I love Carol honestly
Carol's a great dog knows a lot of cool
tricks but oh yes here we go
Carol is evolving so I've been waiting
for this for a long time
Carol is evolved and Carol is evolved
into super Carol all right this is huge
this is awesome because super Carol can
learn new moves so introducing super
Carol super Carol has turn right and
turn around already defined from now on
we'll be using super karo instead of
Carol so Carol is evolved into super
Carol and with super Carol we can call
term right and turn around without
having to define them first they're
built in super Carol
already knows these commands so these
are the commands that super Carol knows
super Carol knows move football take
ball turn left and now turn right and
turn around now you may have noticed
that I snuck in that word API up into
the title of this slide so let's talk
about what exactly an API is so
introducing API is an API is an
application programming interface it is
just a set of tools for building
programs that's what an API is so what
is an API is an application programming
interface that's what it stands for but
that's not really important what is
important is what it actually means an
API is a set of tools for building
software which is just another word for
program a good API makes it easier to
develop a program by providing all the
necessary building blocks and these
building blocks are then put together by
the programmer that's you so I'm gonna
let you in on a little secret you've
actually been programming in a language
called Python this entire time
you've been writing Python functions
Python commands full Python programs
Python is a full professional language
that is one of the most widely used
programs in the world
so how does this relate to api's well
karo is an API care was an API built in
Python to make it easier to build cool
programs the Carroll API abstracts away
the complex details involved in getting
care of the dog to move across the
screen there's a lot of complex things
going on to get a picture of a dog to
move across the screen but we don't have
to worry about any of that
we just type the Python command move and
Karel API takes care of the rest the
super Karel API is even better the super
camera API is exactly the same as the
Karel API but it has some new additions
in addition to extracting away the
process involved in getting Karel to
move across the screen it abstract away
the details involved in getting Karel to
turn right and turn around it used to be
that we have to define those functions
every single time we wanted to use them
but now those are built into the API we
don't have to worry about how these work
behind the scenes this is the Karel API
and the API is the building blocks we
can use these are the commands Cairo
knows move put ball take ball and turn
left the super it Karel API is the same
but we've also added turn right and turn
around so now one more thing about API
that's important and that's the
documentation documentation is an
important part of API is because it
provides the information to show the
programmer that's you how to use it if
you haven't checked out the docs tab yet
this is where all the documentation for
Carol and super Carol lives when we go
to the docs we can see
documentation all the information about
this API how to use it the proper syntax
things like that are all included in
this documentation so that's the API
documentation and that's super Carol now
let's go explore some in the editor ok
so we're going to look at revisiting our
hurdle peril so if you remember this
program had Carol running a set of
hurdles and we basically have said ok
our basic program down here
run to a hurdle jump the hurdle run to
the next hurdle jump that hurdle and
then run to the finish and we didn't
know you were originally using Carol
that did not know turn right and so when
we ran we would see Carol kinda come up
I'm when it get got up on Carol got up
here can I would turn left three times
so that that Carol could can then
continue with their moves so what we can
do though is we can actually delete this
here and now we're going to notice the
Carol knows how to turn right because
this is super parallel and with Super
Carol we can see that that command so
still execute without us having to
define it so we still have our turn
right commands in here and we're gonna
notice too that when Carol does do this
watch what she does are here so Carol
turns and Carol actually turns right try
was not turning left three times but
actually making a right turn so that's
how we use super Carol we're basically
same commands as before beware adding
the turn right in the turn around and we
don't have to define those commands over
here it's not your turn to play around
