as file I'm going to go ahead and say
2,411.099
6.181
this for line in file and then below
2,413.619
4.98
this I'm going to do exactly as before
2,417.28
3.66
name comma house equals the current line
2,418.599
4.441
stripping off the white space at the end
2,420.94
4.56
splitting it on a comma so that's exact
2,423.04
5.94
same as before but this time before I go
2,425.5
7.2
about uh printing the sentence I'm going
2,428.98
5.58
to store it temporarily in a list so
2,432.7
3.36
that I can accumulate all of these
2,434.56
3.72
sentences and then sort them later so
2,436.06
4.14
let me go ahead and do this students
2,438.28
5.039
which is my list dot append let me
2,440.2
4.98
append the actual sentence I want to
2,443.319
3.54
show on the screen so another F string
2,445.18
5.52
so name is in house just as before but
2,446.859
5.46
notice I'm not printing that sentence
2,450.7
4.44
I'm appending it to my list not a file
2,452.319
5.881
but to my list why am I doing this well
2,455.14
4.86
just because as before I want to do this
2,458.2
5.82
for student in the sorted students I
2,460
6.359
want to go ahead and print out students
2,464.02
4.5
like this well let me go ahead and run
2,466.359
5.581
python of students.pi and hit enter now
2,468.52
5.88
and I think we'll see indeed Draco is
2,471.94
4.02
now first Harry a second Hermione is
2,474.4
4.86
third and Ron is fourth but this is
2,475.96
6.659
arguably a little sloppy right it seems
2,479.26
5.04
a little hackish that I'm constructing
2,482.619
3.661
these sentences and even though I'm
2,484.3
5.16
technically want to sort by name I'm
2,486.28
4.74
technically sorting by these whole
2,489.46
4.2
English sentences so it's not wrong it's
2,491.02
5.04
achieving the intended result but it's
2,493.66
4.14
not really well designed because I'm
2,496.06
3.42
just kind of getting lucky that English
2,497.8
3.059
is reading from left to right and
2,499.48
2.639
therefore when I print this out it's
2,500.859
3.661
sorting properly it would be better
2,502.119
4.141
really to come up with a technique for
2,504.52
4.92
sorting by the students names not by
2,506.26
4.68
some English sentence that I've
2,509.44
3.84
constructed here on line six
2,510.94
4.62
so to achieve this I'm going to need to
2,513.28
4.319
make my life more complicated for a
2,515.56
4.74
moment and I'm going to need to collect
2,517.599
5.76
information about each student before I
2,520.3
4.86
bother assembling that sentence so let
2,523.359
4.021
me propose that we do this let me go
2,525.16
4.199
ahead and undo these last few lines of
2,527.38
4.5
code so that we currently have two
2,529.359
5.101
variables name and house Each of which
2,531.88
3.84
has name in the student's house
2,534.46
2.94
respectively and we still have our
2,535.72
4.26
Global variable students but let me do
2,537.4
4.38
this recall that python supports
2,539.98
3.839
dictionaries and dictionaries are just
2,541.78
4.2
collections of keys and values so you
2,543.819
3.901
can associate something with something
2,545.98
4.68
else like a name with Hermione like a
2,547.72
5.399
house with Gryffindor that really is a
2,550.66
4.38
dictionary so let me do this let me
2,553.119
4.621
temporarily create a dictionary that
2,555.04
5.16
stores this Association of name with
2,557.74
4.8
house let me go ahead and do this let me
2,560.2
4.8
say that the students here is going to
2,562.54
4.02
be represented initially by an empty
2,565
2.819
dictionary and just like you could
2,566.56
2.34
create an empty list with square
2,567.819
2.221
brackets you can create an empty
2,568.9
3.719
dictionary with curly braces so give me
2,570.04
4.26
an empty diction missionary that will
2,572.619
4.861
soon have two keys name and house how do
2,574.3
4.799
I do that well I could do it this way
2,577.48
4.8
student Open Bracket name
2,579.099
5.881
equals the student's name that we got
2,582.28
5.24
from the line student bracket house
2,584.98
5.22
equals the house that we got from the
2,587.52
5.92
line and now I'm going to append to the
2,590.2
6.6
students list plural that particular
2,593.44
5.639
student now why have I done this I've
2,596.8
4.08
admittedly made my code more complicated
2,599.079
4.02
it's more lines of code but I've now
2,600.88
4.439
collected all of the information I have
2,603.099
4.801
about students while still keeping track
2,605.319
5.161
what's a name what's a house the list
2,607.9
4.8
meanwhile has all of the students names
2,610.48
4.8
and houses together now why have I done
2,612.7
4.56
this well let me for the moment just do
2,615.28
4.38
something simple let me do for students
2,617.26
4.62
in students and let me very Simply Now
2,619.66
5.76
say print the following F string the
2,621.88
6.38
current student with this name
2,625.42
5.159
uh is in
2,628.26
5.2
this current student's house
2,630.579
5.76
and now notice one detail inside of this
2,633.46
4.859
F string I'm using my curly braces as
2,636.339
2.941
always
2,638.319
3.121
I'm using inside of those curly braces
2,639.28
4.74
the name of a variable as always but
2,641.44
4.8
