[Tutor] Sorting/filtering data, dictionary question & Re:OT
Hi,
I have a couple of questions about a program I've been working on. Here's a
overview of what the program does.
Calculates the following data about HVAC/Plumbing pipe:
A). Total volume of water inside the pipe (US gallons).
B). The weight of the water inside the pipe.
C). The actual weight of the pipe, itself.
There's a total of six different types of pipe to choose from and within that
group of six, there's a total of 100 different sizes. Sizes range from 1/2" to
48". The user enters pipe lengths into a GUI and then clicks on a pushButton
to write the data out to a csv file. A dialog then pops up and gives the user
the option to open the csv file (with OpenOffice Calc).
Using suggestions I received from the Tutor List, I created a dictionary for
the program that holds various data about the pipes. The dict holds pipe
sizes, inside diameters, names of the lineEdits on the GUI, weight of the pipe
per foot, etc.
So, the user enters various pipe lengths, and using the dictionary the program
calculates the totals, the totals go into a list, the list gets sorted and
then the sorted list is written to csv file.
One problem I ran into was sorting my lists. The dictionary I initially came
up with contained a pipe size designation in this format: 1/2", 3/4", 1", etc.
This format is the standard way to write pipe sizes (at least in the US
anyway). When I sorted the data (using this format), I found that the inches
didn't sort the way I wanted them to.
For example:
>>>sizes = ['1/2"', '3/4"', '1"', '1-1/4"', '1-1/2"']
>>>sizes.sort()
>>>sizes
['1"', '1-1/2"', '1-1/4"', '1/2"', '3/4"']
>>>
Although Python is sorting exactly as it is supposed to, I needed the inches
to be in sequential order. Not knowing what to do, I added another size to the
dictionary before each of the "inch sizes". This new "size" has this type of
format: .5, .75, 1, 1.25, 1.5, etc. And when the data is sorted, it works
perfectly. But now I was left with both a "size" and an "inch size" and I only
wanted the "inch size" in the pipe reports (the csv file).
Below is a small section of the dictionary the program uses (pipeDict). I'm
also providing two functions to give you a general idea of how I'm:
1). Creating and sorting the pipe data and
2). How I'm filtering the "size" out of the list.
pipeDict = \
{('lineEdit1','Steel(Std)',.5,'1/2"',.85): .622,
('lineEdit2','Steel(Std)',.75,'3/4"',1.13): .824,
('lineEdit3','Steel(Std)',1,'1"',1.678): 1.049,
('lineEdit4','Steel(Std)',1.25,'1-1/4"',2.272): 1.38,
('lineEdit5','Steel(Std)',1.5,'1-1/2"',2.717): 1.61,
('lineEdit6','Steel(Std)',2,'2"',3.652): 2.067,
('lineEdit7','Steel(Std)',2.5,'2-1/2"',5.79): 2.469,
('lineEdit8','Steel(Std)',3,'3"',7.57): 3.068,
('lineEdit9','Steel(Std)',3.5,'3-1/2"',9.11): 3.548,
('lineEdit10','Steel(Std)',4,'4"',10.79): 4.026,
('lineEdit11','Steel(Std)',5,'5"',14.62): 5.047,
('lineEdit12','Steel(Std)',6,'6"',18.97): 6.065,
('lineEdit13','Steel(Std)',8,'8"',28.55): 7.981,
('lineEdit14','Steel(Std)',10,'10"',40.48): 10.02}
def somePipeReport():
report = []
for name, typ, size, inchSize, weight in pipeDict:
report.append((typ,size,inchSize,weight))
report.sort()
newReport = filterPipeData(report)
print newReport
def filterPipeData(data):
filteredData = []
for typ, size, inchSize, weight in data:
filteredData.append((typ,inchSize,weight))
return filteredData
The two functions above are not *exactly* what I'm using, but it's close
enough to give you an idea of how I'm removing the "size" data. The reason I
created a separate function to filter the "size" out is because I currently
have two reports within the program. I figured it would be better to create
one function that each report could call to filter data. I also thought that
if I create any additional reports in the future, those reports could utilize
the same function as well.
Question #1:
Am I going about this sorting and filtering thing correctly or have I just
gone insane? My gut feeling is, there's probably an easier/smarter way to do
this.
Question #2:
As I mentioned above, this program calculates the water volume inside of the
pipe. I do that using this function:
def volCalc(ID, length):
from math import pi
gal = ((ID*.5)**2)*pi*(12*length)/(230.9429931)
return gal
The ID (inside diameter) is pulled from pipeDict (it's the value in the
dictionary) and the length comes from user input. What I'm wondering is,
would it be a better idea to store in the dictionary a "gallon per foot value"
for each pipe? For example, looking at 10" Steel(Std) pipe in the above
dictionary we find that this type & size of pipe has an ID of 10.02 (inches).
When we plug this ID and a length of 1 foot into the volCalc() function it
returns a total of 4.10 gallons (rounded). Would it

In the bin directory, find the script called "config_list". From the help file
(./config_list --help):
--outputfile filename
-o filename
Instead of configuring the list, print out a list's configuration
variables in a format suitable for input using this script. In this
way, you can easily capture the configuration settings for a
particular list and imprint those settings on another list. filename
is the file to output the settings to. If filename is `-', standard
out is used.
Dont forget to supply the list name in the command line.
For example:
config_list -o outfile.txt mylist

In principle you are right but due to the way Python works you might be faster doing a sort on the list first, then you only need to search until you pass the place where the entry should be... This will be faster if you have to search for several items, and might be faster even for one since the sort is written in C but the for loop will be in Python...

[Tutor] A not-so-basic question...
Hi folks...
I was thinking about this the other day while prepping to write up
another CGI thing.
It occurred to me to wonder how other folks prepare an app, script,
whatever.
So the question is, and I am not looking for a "right answer" here. (I
doubt ther eis one, to be honest.)
How do you go about setting up a new application?
For example, suppose I need a script that will collect order information
for a set of items ona page. Its output will go to a mail program so the
artist can be notified.
I know that the script needs to be somewhat customizable since more
than one person will use it, and I want to look to the future where such a
script might get superceded for something like credit card orders, or
possible integration with a larger order processing scheme.
I'd start out by commenting goals in a new file, like so:
--
# Initialize variables
# Gather form data
# Output results
--
Then I'd go back through each comment and either call modules I've
prewritten, or write new defs.
Then I'd add import statements to cover the modules and the defs:
--
from datetime import now
import cgi
from mailman import send
# Initialize variables
form = cgi.FieldStorage()
# Gather form data
for each in form:
blah
blah
# Output results
result = {}
send(result)
And so on.
So the question is, how do you do it?
Is there a method you prefer? Something tried and true, or maybe
foolproof?
Just curious... And maybe a bit hopeful someone has a better way than
mine. Seems like I do an awful lot of testing... :)

Hi Dave,
Hmmm... what kind of data is being copied here? Python's data structures
are desigined for flexibility, but sometimes that flexibility comes at the
cost of some space. If we knew more about the data that's being stored,
maybe we can think of a more compact representation.

Perhaps we can avoid making a separate copy of the data? Copying data
structures can often be avoided. Why does your program try to copy the
data structure?
(Aside: one nonobvious example where copying can be avoided is in Conway's
Game of Life: when we calculate what cells live and die in the next
generation, we can actually use the 'Command' design pattern to avoid
making a temporary copy of the world. We can talk about this in more
detail if anyone is interested.)

Whenever we reassign to self.old_data:
self.old_data = self.data
then whatever self.old_data was pointing at, before the assignment, should
get garbage collected, if there are no other references to the old data.
The code there isn't really doing any copying at all, but is rather just
constructing a whole new empty data structure into 'self.data'. If so,
then it does seem that you can avoid copying.
I'd love to know a little bit more about the data that the program is
collecting; if you have time, please feel free to tell us more details.
Good luck to you!

[Tutor] Am I storeing up problems ?
Hi there again,
My matrix 'self.data' consists of a list of 110 items, each item is a
dictionary of 250 keys, each key holds two lists, one of four items, one
of 12 items.
I needed to copy this matrix to 'self.old_data', so I have been using
.deepcopy(), which works OK but is SLOW (12+ secs)
Once the matrix is copied, 'self.data' is re-constructed as the
programme gathers data.
To speed things up I changed my code to
# This is the speeded up deepcopy()
self.old_data = self.data
self.data = []
for i in range(110):
self.data.append({})
Query: Is all this OK, it works and quick as well, but I am concerned I
may be leaving garbage in the Python PVM since I am shrugging off old

That's a small example, but it will work equally well with a long

These results are unsurprising. 8^)
A list of 250 words is no problem -- "Moby Dick" has a couple hundred thousand:

You might want to try: x in list this will return true if, for example, list = [x,y,z,w], false if list = [y,y,y,y] Bill Dave S wrote: OK simple query, I have a list consisting of about 250 items, I need to know if a particular item is in the list. I know this is better suited to a dictionary but thats not the way it ended up ;-) I could do a for loop to scan the list & compare each one, but I have a suspission that there is a better way ?

I put the docstring just like in the example at the link you provided... Please post the code for the module you are testing. Also, anything I can do... Presently, since I'm running windows xp, I would have to hunt for the command prompt and type in the command '"C:\python24\python.exe" "C:\documents and settings\jacob\desktop\working python programs\testmodules.py" -v' You should put C:\python24 in your PATH environment variable. Not sure how to do that on XP; on Win2K I - right-click My Computer and select Properties - click the Advanced tab - click Environment Variables - find the System variable Path and edit it - append ";C:\python24" to Path (no quotes; the semicolon is needed, it is a separator for the Path variable) - click OK a few times - restart your DOS shell so it gets the new variable Now you should be able to open a command line in the directory containing your program and type > python testmodules.py -v Oh, the light goes on...you want to be able to just double-click testmodules.py. See below for the fix for -v ...or make a batch file to do it for me... How can I make testmodules.py (shown below) append the -v to itself? Is there a self.results or something in testmod? From the docs at http://docs.python.org/lib/doctest-basic-api.html: "Optional argument verbose prints lots of stuff if true" So try doctest.testmod(eval(modtotest), verbose=True) ## testmodules.py ### import doctest modtotest = 'FractionReducer2' exec "import %s" % modtotest doctest.testmod(eval(modtotest)) raw_input() # Since you will be editing this to change the module under test, I don't think there is any benefit to putting the module name in a string. I would write it like this: import doctest import FractionReducer2 as test_module doctest.testmod(test_module, verbose=True) raw_input() This preserves the single point of change when you want to test a different module, but it is IMO much more readable.

A shortcut will suffice, a batch job is overkill for a one liner Alan G. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I guess I'm crazy... : ) > (We already knew that here.) The difference is in how the formatting details work. For numbers the formatting digits indicate precision and for strings length. >>> print "%5.3f" % 123.456 123.4560 >>> print "%5.3s" % 123.456 123. produce very different results.
