system.exist exactly good question but
4,092.96
5.52
no um break again is used to break out
4,096
5.04
of things like loops like we saw earlier
4,098.48
4.799
sys.exit is used to break out of the
4,101.04
5.199
whole program itself use break for loops
4,103.279
4.88
for now and use cis.exit to terminate
4,106.239
4.48
the whole program good question
4,108.159
4.16
other questions now on this program are
4,110.719
4.56
others from where we bring the name of
4,112.319
4.641
the key results
4,115.279
3.281
from where do we get the name of the key
4,116.96
4.64
uh results itself can we change the
4,118.56
4.239
results
4,121.6
3.04
you cannot you so we could in our
4,122.799
3.841
program so the keys that come back in
4,124.64
4
that json response to be clear come from
4,126.64
3.76
itunes.apple.com
4,128.64
3.76
some engineer some team of engineers
4,130.4
4.56
decided for us what all of those keys
4,132.4
4.64
would be called including track name
4,134.96
4.56
results result count and everything else
4,137.04
4.639
you and i can absolutely store those
4,139.52
4.08
same values in variables just like i'm
4,141.679
3.841
doing here with o just like i'm doing
4,143.6
3.84
here with results you can rename those
4,145.52
3.6
keys anything you want using python
4,147.44
4.319
variables but the json response is
4,149.12
5.599
coming from that third-party server
4,151.759
5.841
other questions yes sir so i have a
4,154.719
6.161
question related to cause a package
4,157.6
4.32
so like
4,160.88
2.24
uh yes
4,161.92
4.64
so so what sort of uh ascii graphics uh
4,163.12
5.119
is it capable of
4,166.56
4.639
outputting the calce package um i would
4,168.239
4.801
refer you to the url in the slides
4,171.199
4.241
earlier uh if only because it's more
4,173.04
4.159
thorough they have not just cows but
4,175.44
3.52
tyrannosaurus rex's and several other
4,177.199
3.761
animals as well i should emphasize that
4,178.96
3.52
this is not a package i suspect you will
4,180.96
3.279
use much in the real world it's really
4,182.48
3.679
just meant to be representative of the
4,184.239
3.681
types of packages you can install but
4,186.159
3.52
allow me to refer to the documentation
4,187.92
4.64
for what more is there but ascii art uh
4,189.679
4.961
is the all we had before there were
4,192.56
4.32
emojis let alone gifs and jpegs and
4,194.64
4.96
pings but it's what is immortalized in
4,196.88
5.12
cow say well allow me to transition us
4,199.6
5.36
back now to one final capability of
4,202
5.76
python which is that you yourselves have
4,204.96
5.52
the ability to make your own libraries
4,207.76
5.28
up until now we've been writing all of
4,210.48
5.36
our functions in our one file hello pi
4,213.04
4.96
and everything since and now that we've
4,215.84
5.839
introduced modules in python like random
4,218
5.92
and statistics we can import those that
4,221.679
3.681
come with python but that's other
4,223.92
3.52
people's code as well and we've now used
4,225.36
3.839
pip this package manager to install
4,227.44
3.6
third-party packages as well in the
4,229.199
3.601
system and using other people's code
4,231.04
2.639
still
4,232.8
2.879
but to come full circle what if you
4,233.679
4
yourself find yourself implementing the
4,235.679
4.56
same kinds of functions again and again
4,237.679
4.401
or you find yourself opening up old
4,240.239
3.92
programs copying and pasting code you
4,242.08
4.079
wrote into new programs because you have
4,244.159
4.161
the same problem yet again a good
4,246.159
4.881
practice would be to somehow bundle up
4,248.32
5.28
that code you keep reusing and make your
4,251.04
5.04
own python module or package you can
4,253.6
4.48
keep it local on your own mac or pc or
4,256.08
4.48
cloud server or you can go through the
4,258.08
4.32
steps of actually bundling it up making
4,260.56
3.599
it free in open source and putting it on
4,262.4
4.319
something like pi pi for others to use
4,264.159
4.481
as well okay i'm going to go ahead and
4,266.719
4.48
run code of sayings.pi to create a brand
4,268.64
4.32
new file called sayings.pi which is
4,271.199
4.241
going to be my own sayings module i'm
4,272.96
3.92
going to define a couple of simple
4,275.44
3.12
functions in there i'm going to define a
4,276.88
3.52
hello function that's going to take a
4,278.56
4
name parameter as input and that
4,280.4
4.64
function is simply going to print out an
4,282.56
4.96
f string that contains hello comma and
4,285.04
4.08
then in curly braces whatever that
4,287.52
3.84
person's name actually is
4,289.12
3.52
then i'm going to go ahead and define
4,291.36
3.44
one other function a goodbye function
4,292.64
5.36
that has def goodbye also takes a name
4,294.8
5.439
as its input and then that prints out by
4,298
4.719
contrast an f string that says goodbye
4,300.239
5.601
comma and then in curly braces name and
4,302.719
5.281
now just for good measure just so i can
4,305.84
3.92
be sure that these functions are working
4,308
3.04
as expected i'm going to go ahead and
4,309.76
3.6
