Keywords

💡Super Carol

Super Carol is a term used to describe an evolved version of the character Carol, a dog in the video's programming context. It signifies an upgrade from the original Carol, implying enhanced capabilities and features. In the video, Super Carol is introduced as having built-in commands such as 'turn right' and 'turn around,' which were not available with the original Carol, thus making the programming experience more efficient and user-friendly.

💡API (Application Programming Interface)

API stands for Application Programming Interface, which is a set of protocols, tools, and definitions that allows different software applications to communicate with each other. In the context of the video, the API is used to abstract the complexities of programming by providing a set of predefined commands that can be used to control the character Carol. The video emphasizes the importance of APIs in simplifying the development process by offering ready-to-use building blocks for programmers.

💡Evolution

In the video, the term 'evolution' is used metaphorically to describe the process of enhancement or improvement of a software component, specifically referring to the transition from Carol to Super Carol. It implies a progression to a more advanced state, where Super Carol has additional features and capabilities compared to the original Carol.

💡Commands

Commands in the context of the video refer to the specific instructions given to the character Carol, such as 'move,' 'turn left,' 'turn right,' and 'turn around.' These commands are part of the API that controls Carol's actions within the programming environment. The introduction of new commands with Super Carol, such as 'turn right' and 'turn around,' demonstrates the expansion of the API's functionality.

💡Python

Python is a high-level, interpreted programming language known for its readability and efficiency. In the video, Python is mentioned as the language in which the APIs for Carol and Super Carol are built. It highlights that the viewers have been using Python functions and commands without necessarily being aware of it, emphasizing Python's role in making programming more accessible.

💡Abstraction

Abstraction in programming refers to the concept of hiding the complex reality while exposing only the necessary parts. In the video, the Karel API and Super Karel API provide abstraction by handling the complex details of moving the character Carol across the screen, so the programmer does not need to deal with these intricacies directly.

💡Documentation

Documentation in the context of APIs is crucial as it provides information on how to use the API effectively. The video mentions the 'docs' tab as the place where all documentation for Carol and Super Carol is located, including information on syntax and usage, which is essential for programmers to understand and utilize the API correctly.

It serves as an example to illustrate the use of commands and the evolution from Carol to Super Carol, showing how the new 'turn right' command simplifies the process of navigating around obstacles.

💡Built-in

The term 'built-in' in the video refers to features or commands that are already included within the Super Carol API, such as 'turn right' and 'turn around.' This means that programmers do not need to define these commands each time they want to use them, as they are part of the API's standard functionality, streamlining the programming process.

💡Programmer

A programmer is an individual who writes code for software applications. In the video, the term is used to refer to the viewers or users of the API, who are the ones utilizing the commands and features of Carol and Super Carol to build their programs.

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
