and it's even doing some error checking | 8,720.359 | 3.441 |
to make sure that the name was actually | 8,721.88 | 5.08 |
passed in meanwhile student is | 8,723.8 | 5.44 |
inheriting all of that functionality and | 8,726.96 | 4.28 |
using it by calling the super class's | 8,729.24 | 4 |
own init method but it's additionally | 8,731.24 | 3.64 |
taking the house that's presumably | 8,733.24 | 3.44 |
passed into the student Constructor | 8,734.88 | 4 |
function and assigning it to its own | 8,736.68 | 4.28 |
instance variable self. house and | 8,738.88 | 4.16 |
similarly Professor are restoring in | 8,740.96 | 4.24 |
self-thought subject the subject that | 8,743.04 | 4.76 |
was passed into there that one as well | 8,745.2 | 4.88 |
now how might we use these classes well | 8,747.8 | 4.36 |
we'll continue to wave our hands with a | 8,750.08 | 3.76 |
little bit of detail here but if at the | 8,752.16 | 3.279 |
bottom of this file or any other file | 8,753.84 | 3.96 |
that Imports this one I could now write | 8,755.439 | 4.281 |
code like this I could create a student | 8,757.8 | 4.08 |
variable and assign it the return value | 8,759.72 | 3.679 |
of the student Constructor call and | 8,761.88 | 4.08 |
maybe that student is named Harry and | 8,763.399 | 4.96 |
that student's house for instance might | 8,765.96 | 5.399 |
be Gryffindor and meanwhile I might do | 8,768.359 | 5.241 |
something like this professor equals | 8,771.359 | 3.801 |
professor over here and notice the | 8,773.6 | 4.48 |
lowercase s on the left capital S on the | 8,775.16 | 4.72 |
right same for Professor on the left | 8,778.08 | 3.72 |
lowercase and uppercase on the right | 8,779.88 | 4.16 |
respectively Professor quote unquote | 8,781.8 | 6.36 |
seus and how about defense against the | 8,784.04 | 6.68 |
dark arts will be his subject and | 8,788.16 | 4.48 |
meanwhile if we want more generically | 8,790.72 | 4.48 |
just a wizard who at the moment is | 8,792.64 | 4.799 |
neither student nor Professor teaching | 8,795.2 | 4.119 |
classes actively we could even do that | 8,797.439 | 4.721 |
we could do wizard equals wizard in | 8,799.319 | 4.521 |
capital W on the right hand side of the | 8,802.16 | 2.96 |
equal sign because it's the name of the | 8,803.84 | 3.84 |
class and someone like Alin passing in | 8,805.12 | 6.68 |
only albus's name not a house not a | 8,807.68 | 6.48 |
subject because in this case he's known | 8,811.8 | 5 |
only as a wizard meanwhile with each of | 8,814.16 | 4.88 |
these calls this line of code here will | 8,816.8 | 3.679 |
ensure that the init method for the | 8,819.04 | 3.64 |
wizard class is called this line of code | 8,820.479 | 4.441 |
here will ensure that the init method of | 8,822.68 | 4.2 |
the student class and in turn the init | 8,824.92 | 3.68 |
method of the super class wizard is | 8,826.88 | 3.72 |
called and then lastly on this final | 8,828.6 | 4.839 |
line of code will this syntax ensure | 8,830.6 | 4.6 |
that the init method of the professor | 8,833.439 | 3.721 |
class is called which in turn calls the | 8,835.2 | 5.04 |
init method of the super class as well | 8,837.16 | 5.72 |
any questions now on this idea of | 8,840.24 | 5.36 |
inheritance which is a key feature of a | 8,842.88 | 3.8 |
lot of | 8,845.6 | 3.759 |
objectoriented programming languages um | 8,846.68 | 6.44 |
so is there any situation where because | 8,849.359 | 5.401 |
uh from what I've seen so far A lot of | 8,853.12 | 3.52 |
times there's like a lot of nesting if | 8,854.76 | 3.519 |
you do superar does it go one up is | 8,856.64 | 3.36 |
there any situation where you know it's | 8,858.279 | 5.521 |
nested in another class as well um above | 8,860 | 5.72 |
wizard let's say a really good question | 8,863.8 | 4.04 |
if you were to have a a super super | 8,865.72 | 4.04 |
class so your hierarchy is even taller | 8,867.84 | 4.96 |
than the two levels of uh hierarchy that | 8,869.76 | 5.16 |
we currently have absolutely but what's | 8,872.8 | 4.04 |
nice about object-oriented Pro what's | 8,874.92 | 3.519 |
nice about inheritance as the name | 8,876.84 | 3.479 |
implies is just as you might have | 8,878.439 | 4.241 |
inherited certain traits as a human from | 8,880.319 | 4.641 |
your grandfather and grandmother or your | 8,882.68 | 4.28 |
great-grandfather or great-grandmother | 8,884.96 | 4.439 |
some of those properties can actually uh | 8,886.96 | 4.24 |
trickle down to you so to speak in the | 8,889.399 | 5.201 |
context of code as well so when you | 8,891.2 | 6.44 |
descend from another class that is when | 8,894.6 | 6.04 |
you subass a a super class or a super | 8,897.64 | 5.16 |
super class you actually do inherit all | 8,900.64 | 3.759 |
of the functionality not just from one | 8,902.8 | 3.96 |
level above you but from two or three so | 8,904.399 | 4 |
you can indeed access some of that | 8,906.76 | 3.24 |
functionality as well and you can even | 8,908.399 | 3.641 |
override it if you want some of these | 8,910 | 3.399 |
classes to behave a little bit | 8,912.04 | 4.48 |
differently than others other questions | 8,913.399 | 5.561 |
on inheritance so it's kind of similar | 8,916.52 | 4.12 |
to the last one but can you have like | 8,918.96 | 4.84 |
two parents on the same level a really | 8,920.64 | 5.16 |
good question so there are ways to | 8,923.8 | 5.12 |
implement uh um descendants from | 8,925.8 | 4.519 |
multiple parents and there's different | 8,928.92 | 3.12 |
ways to do this not just in Python but | 8,930.319 | 3.841 |
other languages we've kept things simple | 8,932.04 | 4.16 |
here though by having a single uh | 8,934.16 | 4.48 |
inheritance path a good question how | 8,936.2 | 4.8 |
about one more question on inheritance | 8,938.64 | 5.56 |
can we have multiple arguments in | 8,941 | 7.359 |
