json or write it as well and it's a | 3,423.119 | 4.401 |
completely text based format which means | 3,425.44 | 4.72 |
that if i visit that url with my browser | 3,427.52 | 4.4 |
what gets downloaded is just a bunch of | 3,430.16 | 4.24 |
text but that text is formatted in a | 3,431.92 | 5.04 |
standard way using curly braces and | 3,434.4 | 5.12 |
square brackets using quotes and some | 3,436.96 | 4.879 |
colons that ultimately contains all of | 3,439.52 | 4.72 |
the information in apple's database on | 3,441.839 | 4.48 |
weezer's song at least the first one | 3,444.24 | 4.16 |
because i limited it to one in their | 3,446.319 | 3.921 |
database and that's an api an | 3,448.4 | 3.439 |
application programming interface a | 3,450.24 | 4.319 |
mechanism whereby i can access data on | 3,451.839 | 4.48 |
someone else's server and somehow | 3,454.559 | 3.841 |
integrate it into my own | 3,456.319 | 4.641 |
program now of course my browser chrome | 3,458.4 | 4 |
is not something i wrote i should | 3,460.96 | 3.2 |
actually write some python code that | 3,462.4 | 4.24 |
perhaps pretends to be a browser to grab | 3,464.16 | 4.8 |
the same data so let's do that let me go | 3,466.64 | 3.919 |
back to vs code here and let me write a | 3,468.96 | 4.72 |
program with code itunes.pi and we're | 3,470.559 | 5.04 |
going to write some code by which i can | 3,473.68 | 3.439 |
then use | 3,475.599 | 4.881 |
the itunes api and in turn python to get | 3,477.119 | 5.761 |
information about any band that i might | 3,480.48 | 4.319 |
want i'm going to go here and import | 3,482.88 | 4.64 |
first the requests library which i | 3,484.799 | 4.721 |
installed earlier in order to make those | 3,487.52 | 4.64 |
http requests i'm going to go ahead and | 3,489.52 | 4.88 |
import the sys library by which i'll | 3,492.16 | 4 |
have the ability to use command line | 3,494.4 | 4.08 |
arguments like specification of the band | 3,496.16 | 4.399 |
that i want to search for if not weezer | 3,498.48 | 3.839 |
and then down here i'm going to go ahead | 3,500.559 | 5.121 |
and insert some error checking to say if | 3,502.319 | 5.921 |
the length of sys.rgv | 3,505.68 | 5.6 |
does not equal 2 so if the user does not | 3,508.24 | 4.48 |
provide me with the name of the file | 3,511.28 | 3.92 |
they want to run and the name of a band | 3,512.72 | 4.399 |
and that's it you know what let's just | 3,515.2 | 4.32 |
go ahead and exit for now i could | 3,517.119 | 4.081 |
provide a more explanatory message but | 3,519.52 | 2.96 |
for now i'm going to keep things simple | 3,521.2 | 3.76 |
and just exit the program prematurely so | 3,522.48 | 5.359 |
that i can trust hereafter that sys.rt | 3,524.96 | 4.32 |
has what i want | 3,527.839 | 4 |
and now i have the opportunity to use | 3,529.28 | 4.72 |
the requests library to write some | 3,531.839 | 3.921 |
python code that effectively is | 3,534 | 4.64 |
pretending to be a web browser so as to | 3,535.76 | 5.92 |
connect to that same https url on | 3,538.64 | 5.439 |
apple's own server so now that i've | 3,541.68 | 4.08 |
guaranteed that the user has typed in | 3,544.079 | 3.921 |
not just the name of the file but also | 3,545.76 | 4.4 |
the name of a band at the prompt giving | 3,548 | 4.96 |
me a length of 2 for sys.rgv let's go | 3,550.16 | 5.439 |
ahead and execute requests.get which is | 3,552.96 | 5.04 |
a function inside of the request package | 3,555.599 | 4.321 |
that will literally get some response | 3,558 | 4.079 |
from a server and the url that i want to | 3,559.92 | 4.879 |
get is exactly the same as before https | 3,562.079 | 4.081 |
colon slash | 3,564.799 | 3.361 |
itunes.apple.com | 3,566.16 | 5.04 |
search question mark entity equal song | 3,568.16 | 6 |
ampersand limit equals one ampersand | 3,571.2 | 5.68 |
term equals previously weezer but let's | 3,574.16 | 4.639 |
make this program a little interactive | 3,576.88 | 4.479 |
and actually allow the human to specify | 3,578.799 | 4.481 |
at the command line what artists they'd | 3,581.359 | 3.681 |
like to search for so i'm going to go | 3,583.28 | 4.4 |
ahead and close my quote early and just | 3,585.04 | 5.279 |
append using the concatenation operator | 3,587.68 | 5.52 |
as in the past sis.rgv | 3,590.319 | 5.52 |
bracket 1. and now it'd actually be nice | 3,593.2 | 4.8 |
to store the response from the server in | 3,595.839 | 3.601 |
a variable so i'm going to go ahead and | 3,598 | 4.799 |
say response equals and to store all of | 3,599.44 | 4.56 |
the response that comes back from the | 3,602.799 | 3.201 |
server in a variable called response | 3,604 | 3.76 |
down here now i'd like to just | 3,606 | 3.44 |
understand what the server is returning | 3,607.76 | 3.76 |
to me to make sure i know how next to | 3,609.44 | 3.84 |
proceed so this isn't going to be very | 3,611.52 | 3.039 |
pretty yet but i'm going to go ahead and | 3,613.28 | 2.519 |
print out | 3,614.559 | 4 |
response.json which ensures that the | 3,615.799 | 4.841 |
data i'm getting back is formatted on my | 3,618.559 | 4.721 |
screen as exactly that json the same | 3,620.64 | 5.36 |
text format as we saw on my screen it's | 3,623.28 | 4.799 |
not a useful program yet i'm really just | 3,626 | 3.92 |
learning along the way but let me go | 3,628.079 | 3.361 |
ahead now and increase the size of my | 3,629.92 | 4.12 |
terminal window and run python of | 3,631.44 | 5.04 |
itunes.pi and type in the name of a band | 3,634.04 | 4.759 |
like weezer and hit enter | 3,636.48 | 4.48 |
and what we see on the screen formatted | 3,638.799 | 4.56 |
almost the same as before is exactly | 3,640.96 | 4.879 |
that same text but what you'll see here | 3,643.359 | 4.72 |
