Harry so what have I done I've not | 7,352.4 | 5.48 |
bothered instantiating an object of type | 7,355.079 | 6.281 |
hat I am just accessing a class method | 7,357.88 | 5.359 |
inside of the Hat class that you know | 7,361.36 | 4.48 |
what is just G to work this is how class | 7,363.239 | 4.241 |
methods work you use the name of the | 7,365.84 | 3.68 |
class capital letter in all | 7,367.48 | 4.8 |
do method name passing in any arguments | 7,369.52 | 4.48 |
you want python is going to | 7,372.28 | 4.359 |
automatically pass in some variable via | 7,374 | 5.639 |
which you can refer to that class in | 7,376.639 | 4.6 |
that function that you've implemented | 7,379.639 | 3.44 |
inside of that class so that I can do | 7,381.239 | 3.88 |
something like this it's not that I want | 7,383.079 | 4.12 |
a variable called houses locally in this | 7,385.119 | 3.681 |
function I want the variable called | 7,387.199 | 3.801 |
houses that's associated with this | 7,388.8 | 5.919 |
current class so I can still access this | 7,391 | 6.56 |
same list that I defined on line six and | 7,394.719 | 4.561 |
now if I go back down here to my | 7,397.56 | 4.92 |
terminal and run python of hat. enter | 7,399.28 | 5.52 |
Harry is still in Hufflepuff once more | 7,402.48 | 4.56 |
Harry is still in Hufflepuff once more | 7,404.8 | 5.48 |
Harry is back in Gryffindor at least | 7,407.04 | 6.639 |
randomly questions now on these class | 7,410.28 | 6.08 |
variables or these class methods which | 7,413.679 | 6.241 |
are in contrast with instance variables | 7,416.36 | 5.96 |
and instance methods and the one thing | 7,419.92 | 4.48 |
at least that's a little strange here is | 7,422.32 | 3.64 |
that even though there's a decorator | 7,424.4 | 4.159 |
called at class method there is not one | 7,425.96 | 5.96 |
called at instance method a method is | 7,428.559 | 5.801 |
just automatically a so-called instant | 7,431.92 | 4.799 |
method when you define it without any | 7,434.36 | 4.839 |
decorator can you have a class inside | 7,436.719 | 5.321 |
another class you can you can Define one | 7,439.199 | 5.201 |
class inside of another generally | 7,442.04 | 4.159 |
speaking this isn't done but there are | 7,444.4 | 3.799 |
cases where it can be helpful especially | 7,446.199 | 4.44 |
for larger more sophisticated programs | 7,448.199 | 5.601 |
so yes it is possible good other | 7,450.639 | 5.761 |
questions the the question was about the | 7,453.8 | 5.359 |
self do houses when you when we remove | 7,456.4 | 7.319 |
it we uh and we pass data the variable | 7,459.159 | 8.721 |
is created itself why we remove the S so | 7,463.719 | 6.601 |
in the previous examples both of the Hat | 7,467.88 | 4.16 |
demonstration and also all of the | 7,470.32 | 5.279 |
student demonstrations we were uh | 7,472.04 | 5.679 |
creating a student object by calling | 7,475.599 | 4 |
student capital S open parenthesis | 7,477.719 | 3.96 |
closed parenthesis with eventually name | 7,479.599 | 4.08 |
and a house passed in and then we were | 7,481.679 | 4.321 |
using the d uh the Double underscore | 7,483.679 | 5.721 |
init method to initialize the self name | 7,486 | 6.559 |
and the self. housee instance variables | 7,489.4 | 6.08 |
therein to those respective values in | 7,492.559 | 5.241 |
this latest version of the Sorting Hat I | 7,495.48 | 4.679 |
haven't bothered with self anywhere only | 7,497.8 | 5 |
because conceptually I don't need or | 7,500.159 | 4.801 |
want there to be multiple hats in the | 7,502.8 | 4.48 |
world I'm just using the class as kind | 7,504.96 | 5.279 |
of a container to bundle up this list of | 7,507.28 | 5.24 |
houses this sorting functionality maybe | 7,510.239 | 4 |
eventually I'll add more functionality | 7,512.52 | 4.52 |
to it but that's it and so sometimes you | 7,514.239 | 4.601 |
can use objectoriented programming in | 7,517.04 | 3.559 |
this somewhat different way when you | 7,518.84 | 3.879 |
want there to be functionality but it's | 7,520.599 | 4.56 |
not specific to any one specific hat | 7,522.719 | 5.601 |
it's specific to the Sorting Hat | 7,525.159 | 5.48 |
itself how about one other question now | 7,528.32 | 5.48 |
on these class variables or methods just | 7,530.639 | 5.04 |
another way of using objectoriented | 7,533.8 | 3.56 |
programming but to solve somewhat | 7,535.679 | 3.321 |
different problem well what's the | 7,537.36 | 4.839 |
difference between the class hat and I | 7,539 | 6.599 |
don't know like a function of hat a good | 7,542.199 | 5.081 |
question so why are we using a class at | 7,545.599 | 4.201 |
all and not just having a file called | 7,547.28 | 5.399 |
hat. with a variable called houses and a | 7,549.8 | 5 |
function called sort like why are we | 7,552.679 | 3.88 |
adding this complexity in this | 7,554.8 | 3.439 |
particular case we don't necessarily | 7,556.559 | 4.6 |
need to I could absolutely go in here I | 7,558.239 | 5.561 |
could get rid of the class I could uh | 7,561.159 | 5.241 |
undo this indentation I could get rid of | 7,563.8 | 4.839 |
this decorator and I could get rid of | 7,566.4 | 5.12 |
hat Dot and I could just do this and | 7,568.639 | 4.641 |
additionally let's see let's get rid of | 7,571.52 | 4.28 |
class here let's get rid of class Here | 7,573.28 | 5.68 |
and Now run python of hat dopy enter and | 7,575.8 | 4.839 |
it still works put Harry in the wrong | 7,578.96 | 3.44 |
house but that's what we H what happens | 7,580.639 | 4.201 |
randomly that's fine too what we're | 7,582.4 | 3.96 |
introducing today by way of | 7,584.84 | 3.279 |
objectoriented programming is just a | 7,586.36 | 4 |
different way of modeling the world it's | 7,588.119 | 4.161 |
not really compelling with an example | 7,590.36 | 3.879 |
like this frankly that's relatively | 7,592.28 | 4.12 |
simple it's not very complex there's not | 7,594.239 | 3.88 |
