24.9
source software for us it's
2,991.44
4
demonstrative of a feature more
2,993.52
3.92
generally here namely being able to
2,995.44
3.76
install these third-party packages and
2,997.44
4.32
how you might do so in python now i'll
2,999.2
4
leave this up on the screen for a moment
3,001.76
3.44
and see if there's any questions about
3,003.2
5.359
cows or tyrannosaurus rex's or packages
3,005.2
5.68
more generally
3,008.559
4
i'm really qualified to speak to just
3,010.88
3.6
one of those
3,012.559
5.121
hi um i've got two questions it's a bit
3,014.48
6.16
earlier than what it's supposed to be um
3,017.68
5.52
so the first question is
3,020.64
3.52
the
3,023.2
4.32
packages that you're calling um
3,024.16
4.24
to
3,027.52
3.44
use in the program
3,028.4
5.36
are they the same as
3,030.96
3.76
um
3,033.76
4.24
let's say because i'm doing java
3,034.72
6.72
the same as calling a class of a java
3,038
4.48
file
3,041.44
4.32
in order to use its functions
3,042.48
6.079
and my second question is
3,045.76
5.359
what's the actual purpose of using
3,048.559
5.441
command line arguments as you use
3,051.119
3.761
because
3,054
5.28
it's not really the best way to
3,054.88
7.12
as you say be user friendly
3,059.28
4.24
where as in
3,062
4.24
let's say the person who's
3,063.52
5.36
using the program doesn't know what it
3,066.24
5.2
what they want what the program's asking
3,068.88
3.52
them
3,071.44
2.56
really good questions the first question
3,072.4
3.84
about the comparison with java python
3,074
4.64
packages are similar to java packages
3,076.24
4.079
where you have something dot something
3,078.64
3.28
dot something at the top of your program
3,080.319
3.28
that gives you access to a class or
3,081.92
3.919
something else python itself supports
3,083.599
4.801
classes more on those down the road and
3,085.839
4.72
you can do very similar things in python
3,088.4
4.08
as you can do with java but the analog
3,090.559
4.481
really is python packages to java
3,092.48
4.879
packages here as for command line
3,095.04
4.64
arguments you ask a good question why do
3,097.359
3.601
we use them especially if they're
3,099.68
3.2
literally yes user friendly they're a
3,100.96
4.399
little less user friendly to people who
3,102.88
5.04
aren't in this zoom to be honest you and
3,105.359
4.161
i as we learn more and more about
3,107.92
3.12
programming and more about command line
3,109.52
3.36
arguments i daresay will become more
3,111.04
4.64
comfortable with and tend to prefer the
3,112.88
4.8
ability to customize commands using
3,115.68
3.76
these command line arguments why
3,117.68
3.76
productivity it tends to make you faster
3,119.44
3.119
because you get into the habit of
3,121.44
2.8
knowing exactly how you can configure
3,122.559
3.841
your software without having to manually
3,124.24
4.56
answer questions and case in point all
3,126.4
3.84
of this time
3,128.8
3.84
have we been running python of something
3,130.24
5.04
dot pi you could imagine not doing that
3,132.64
4.56
you could imagine typing only python
3,135.28
3.92
hitting enter and then you're prompted
3,137.2
3.28
for the name of the file you want to run
3,139.2
3.2
so you type in something.pi and then it
3,140.48
4.4
runs not a big deal but i i would argue
3,142.4
4
that over time you're going to get a
3,144.88
3.12
little tired of that tedium and you
3,146.4
3.28
would much prefer to just automate the
3,148
3.44
command again and again and again
3,149.68
3.439
especially with little conveniences like
3,151.44
3.76
being able to hit up and down in your
3,153.119
4
keyboard history so as to rerun those
3,155.2
4.32
same commands automation is big too if
3,157.119
4.48
you emerge from a class like this and
3,159.52
4.96
start using python to automate processes
3,161.599
4.561
at work or for personal projects or the
3,164.48
3.599
like the ability to specify all of your
3,166.16
3.439
inputs on the one line just means you
3,168.079
4.321
can get work done more quickly so hands
3,169.599
4.881
down absolutely using command line
3,172.4
5.199
arguments is a more arcane uh feature of
3,174.48
5.359
systems that most of us are no longer as
3,177.599
4.24
familiar with because of windows and mac
3,179.839
3.76
os and other operating systems that have
3,181.839
4.24
buttons and guise and menus but the more
3,183.599
4.24
comfortable get you get with programming
3,186.079
3.841
i dare say the more you will tend to
3,187.839
4.081
prefer these capabilities because they
3,189.92
5.04
allow you to do things more quickly
3,191.92
4.96
with that said allow me to propose that
3,194.96
5.44
we take a turn toward yet another
3,196.88
5.92
package that's particularly popular and
3,200.4
4.8
just as easy to install all toward an
3,202.8
5.12
end of using apis now apis are not
3,205.2
4.72
