to just adding more and more attributes | 4,244.04 | 3.44 |
to the class I'm going to pass in all | 4,246.04 | 3.4 |
three of these values instead of just | 4,247.48 | 3.48 |
two I'm not going to do anything | 4,249.44 | 3.04 |
interesting with that value yet but just | 4,250.96 | 3.36 |
to make sure I haven't made things worse | 4,252.48 | 4.44 |
by breaking my code let me run python of | 4,254.32 | 5.28 |
studenty I'll type in Harry I'll type in | 4,256.92 | 4.68 |
Gryffindor and it turns out his Patronis | 4,259.6 | 4.92 |
was a stag and hit enter I haven't seen | 4,261.6 | 4.48 |
what his Patronis is in my output | 4,264.52 | 3.8 |
because I didn't change my stir method | 4,266.08 | 4.079 |
yet but at least I don't have any syntax | 4,268.32 | 3.8 |
error so at least I've not made anything | 4,270.159 | 5.241 |
worse but suppose now I want to have | 4,272.12 | 5 |
functionality not just for initializing | 4,275.4 | 4.72 |
a student and printing out a student if | 4,277.12 | 5.599 |
my class is really meant to be a student | 4,280.12 | 4.64 |
what I can do is not just remember | 4,282.719 | 4.761 |
information about data about students | 4,284.76 | 5.2 |
what's powerful about classes unlike | 4,287.48 | 5.28 |
dictionaries alone is that classes can | 4,289.96 | 5.68 |
have not just variables or instance | 4,292.76 | 4.72 |
variables so to speak those attributes | 4,295.64 | 4.16 |
we keep creating they can also have | 4,297.48 | 5.759 |
functions built in AKA methods when a | 4,299.8 | 5.28 |
function is inside of a class it's | 4,303.239 | 3.721 |
called a method but it's still just a | 4,305.08 | 4.119 |
function at this point we've seen two | 4,306.96 | 5.12 |
functions already two methods called uh | 4,309.199 | 4.401 |
double underscore init and double | 4,312.08 | 3.92 |
underscore stir but those are special | 4,313.6 | 4.639 |
methods and that they just work if you | 4,316 | 4.08 |
define them python calls them | 4,318.239 | 3.841 |
automatically for you but what if you | 4,320.08 | 4 |
wanted to create more functionality for | 4,322.08 | 4.28 |
a student so that your class really | 4,324.08 | 4.36 |
represents this real world or maybe | 4,326.36 | 4.68 |
fantasy world notion of a student where | 4,328.44 | 4.759 |
students not only have names and houses | 4,331.04 | 4.44 |
and patronises they also have | 4,333.199 | 4.841 |
functionality they have actions they can | 4,335.48 | 6.199 |
perform like casting a charm a spell | 4,338.04 | 6.4 |
magically could we implement therefore a | 4,341.679 | 5.761 |
function called charm that actually uh | 4,344.44 | 5.92 |
uses uh their magical knowledge well | 4,347.44 | 4.799 |
let's go ahead and Define our very own | 4,350.36 | 3.76 |
function as follows Let Me Clear My | 4,352.239 | 4.121 |
terminal window scroll back up to my | 4,354.12 | 4.84 |
student class and instead of creating | 4,356.36 | 4.68 |
yet another function that's special with | 4,358.96 | 4.279 |
double underscores I'm going to invent | 4,361.04 | 5.199 |
my own function or method inside of this | 4,363.239 | 5.721 |
class I want to give uh Harry and | 4,366.239 | 4.641 |
Hermione and and all of the other | 4,368.96 | 4.56 |
students the ability to cast charms so | 4,370.88 | 4 |
I'm going to define a function that I | 4,373.52 | 3.56 |
can completely on my own called charm | 4,374.88 | 3.2 |
though I could call this function | 4,377.08 | 3 |
anything I want but because it's a | 4,378.08 | 4.44 |
method inside of a class the convention | 4,380.08 | 3.88 |
is that it's always going to take at | 4,382.52 | 4.28 |
least one argument called self by | 4,383.96 | 5.08 |
convention so that you have access to | 4,386.8 | 4.8 |
the current object even if you don't | 4,389.04 | 4.599 |
plan to use it per se all right let me | 4,391.6 | 3.599 |
go ahead and propose that we Implement | 4,393.639 | 4.121 |
charm in such a way that the method | 4,395.199 | 5.44 |
returns an emoji that's appropriate for | 4,397.76 | 5.68 |
each student's Patronis all right how to | 4,400.639 | 4.56 |
implement this well inside of the charm | 4,403.44 | 4.759 |
method let's go ahead and match on self. | 4,405.199 | 5.201 |
Patronis which is the instance variable | 4,408.199 | 4.04 |
containing a string that represents each | 4,410.4 | 4.36 |
student's petronis and in the case that | 4,412.239 | 5.241 |
it matches a stag for instance for Harry | 4,414.76 | 4.36 |
let's go ahead and return maybe the | 4,417.48 | 5.04 |
closest Emoji this horse here how about | 4,419.12 | 6.2 |
in the case of an otter well in that | 4,422.52 | 6.199 |
case let's go ahead and return oh maybe | 4,425.32 | 5.08 |
the closest match to the otter which | 4,428.719 | 4.641 |
might be this Emoji here and let's see | 4,430.4 | 6 |
in the case of a for for Ron rather than | 4,433.36 | 7.24 |
Hermione a Jack Russell Terrier let's go | 4,436.4 | 6.88 |
ahead and return how about don't have as | 4,440.6 | 4.84 |
many options here why don't we go ahead | 4,443.28 | 4.48 |
and return the cutest available dog in | 4,445.44 | 7.84 |
that case and in the case of no Patronis | 4,447.76 | 7.36 |
recognized as might cover someone like | 4,453.28 | 3.879 |
Draco let's go ahead and use a default | 4,455.12 | 4.72 |
case using the underscore as in the past | 4,457.159 | 4.721 |
and let's go ahead and return for this | 4,459.84 | 3.52 |
oh what should happen if someone doesn't | 4,461.88 | 3.6 |
have a petronis why don't we just see a | 4,463.36 | 4.68 |
magical wand that seems to fizzle out as | 4,465.48 | 4.759 |
in this case all right well now rather | 4,468.04 | 3.52 |
than just print the student let's go | 4,470.239 | 3.361 |
about printing their actual petronis so | 4,471.56 | 3.92 |
I'm going to go down to my main function | 4,473.6 | 3.8 |
here I'm going to still get a student | 4,475.48 | 4.04 |
