Pulling numbers from ASCII filename not working
I searched the archives but couldn't find anyone else with this problem. Basically I'm grabbing all ASCII files in a directory and doing geoprocessing on them. I need to calculate a z-factor based on the latitude of the ASCII file being worked on, which is in the filename. If I type in the code manually it works and reads the latitude value from the ASCII filename, but when run within ArcGIS it crashes when it gets to int(LatString). Isnumber() returned false for Latitude as well. Is there something different about reading values from an ASCII filename? import sys, os, win32com.client, string, gc # Get a list of ASCII files in the workspace for ASCII To Raster conversion filenames = os.listdir(gp.workspace) filenames = [filename.lower() for filename in filenames if (filename[-4:].lower() == ".asc" and filename[0] != "-" )] for filename in filenames: # For each ASCII file, create Hillshade. # account for latitude by computing Z units using radians Latitude = filename[1:3] LatString = str(Latitude) LatInt = int(LatString) radians = LatInt * 0.0174532925 zFactor = 1/(113200 * (cos(radians))) -- http://mail.python.org/mailman/listinfo/python-list
Re: Pulling numbers from ASCII filename not working
The exception I get is "TypeError: Cannot add value 'int' to string." I
have looked at LatString, and it is the string representation of
latitude ('17' etc.). What's odd is that the exception is raised not
when I include LatInt = int(LatString), but when I try to print
LatInt's value or multiply it by another number.
Filenames are along the lines of "N16W110.asc" - is there another way
to get LatString into a number for multiplication purposes?

Re: Pulling numbers from ASCII filename not working
Thank you for the replies, I'm new to Python and appreciate your
patience. I'm using Python 2.1.
To reiterate, the ASCII files in the workspace are being read correctly
and their latitude values (coming from the filenames) are successfully
being converted to string. Even doing LatInt = int(LatString) works,
however the second I try to print LatInt's value or use it in
mathematical operations, the code chokes in ArcGIS.
My full code:
# Import system modules
import sys, os, win32com.client
# Create the geoprocessor object
gp = win32com.client.Dispatch("esriGeoprocessing.GpDispatch.1")
print gp.usage("Hillshade_sa")
print gp.usage("RasterToOtherFormat_conversion")
print gp.usage("DefineProjection_management")
# Check license availability
gp.AddMessage ("ArcInfo license is " + str(gp.CheckProduct("ArcInfo")))
gp.SetProduct("ArcInfo")
gp.CheckOutExtension("Spatial")
# Set workspace
workspace = "E:\\GISTest"
gp.workspace = workspace
gp.AddMessage("Workspace = " + gp.workspace)
filenames = os.listdir(gp.workspace)
filenames = [filename.lower()
for filename in filenames
if (filename[-4:].lower() == ".asc" and filename[0] != "-" )]
for filename in filenames:
# For each ASCII file, create Hillshade.
# account for latitude by computing Z units using radians
Latitude = filename[1:3]
LatString = str(Latitude)
LatInt = int(LatString)
gp.AddMessage("LatInt is " + LatInt)
radians = LatInt * 0.0174532925
zFactor = 1/(113200 * (cos(radians)))
The complete traceback:
Traceback (most recent call last):

>Dude. You're trying to add a string to an int. What did you think would >happen? Dude.

Help with os.spawnv
I've had to migrate back to Python 2.1 and am now trying to use
os.spawnv to get around a memory leak (either in Python or ArcGIS or
both) in a geoprocessing script.
This script (Second Script) gets each Ascii file in the workspace,
converts it to a raster, sets the spatial reference, and hillshades it.
The script works on its own. In the Main Script I can successfully pass
parameters in a list, but no geoprocessing is ever initiated when using
os.spawnv. No errors are being thrown so I don't have a traceback to
post. Help getting this straightened out would be EXTREMELY
appreciated!
Main Script
# Import subprocess module
import os, sys
# Define arguments for subprocess
pyPath = "E:\\Python242\\python.exe"
pyScript = "E:\\Documents and
Settings\\Administrator\\Desktop\\Ian\\GIS\\Python\\subProcess2.py"
workspace = "E:\\GISTest"
# Get a list of ASCII files in the workspace for ASCII To Raster
conversion
filenames = os.listdir(workspace)
filenames = [filename.lower()
for filename in filenames
if (filename[-4:].lower() == ".asc" and filename[0] != "-" )]
for filename in filenames:
# Define Img filename, truncating .asc from inAscii filename
inAscii = workspace + "\\" + filename
outImg = workspace + "\\" + filename[:-4] + ".img"
# Create parameter list
parameterList = []
# First parameter is the name of the Python executable
parameterList.append('python.exe')
# Second parameter is the full path of the Python script
parameterList.append(pyScript)
# The following parameters are the arguments for the Batch script

parameterList.append(outImg)
parameterList.append(outHill)
print parameterList
# Run subprocess
os.spawnv(os.P_WAIT, pyPath, parameterList)
print parameterList
Second Script
I can't post this verbatim for work reasons, but basically it goes:
import sys, os, win32com.client, string
gp = win32com.client.Dispatch("esriGeoprocessing.GpDispatch.1")
gp.SetProduct("ArcInfo")
gp.CheckOutExtension("Spatial")
# For each ASCII file, convert into IMG format
filename = sys.argv[1]
inAscii = sys.argv[2]
outImg = sys.argv[3]
outHill = sys.argv[4]
Do Ascii to raster conversion using inAscii, creating outImg
Set spatial reference
Hillshade using outImg, creating outHill
Convert each hillshade to IMG format, using outHill

Exiting os.spawnv's subroutine
I am using os.spawnv in Python 2.1 to do some geoprocessing in a subroutine/process. Everything works great, except when the processing is done the subroutine just waits for a couple minutes before closing itself and returning to the main script. I have tried using sys.exit() and exit() but these aren't doing anything. What is the proper way to terminate this subroutine upon completion, rather than waiting? Thank you. -- http://mail.python.org/mailman/listinfo/python-list
Re: Exiting os.spawnv's subroutine
My code is below. As a single script there is no pause at the end of
the processing as there is with using os.spawnv... I am using the
P_WAIT value, and wonder if it is responsible for the extra time at the
end of each iteration. Could it take longer for the processing to be
"successful" when run under os.spawnv? Is there a way to manually send
a "success" exit code back to os.spawnv, rather than waiting for it?
Thanks.

Splitting SAX results
Hi list,
I have a very simple SAX script from which I get results like
'Title1:Description','Title2:Description'. I want to split each result
on the colon, using the two resulting elements as key/value pairs in a
dictionary. I've tried a couple different approaches with lists etc,
but I keep getting an 'IndexError: list index out of range' when I go
to split the results. Probably an easy fix but it's my first hack at
SAX/XML. Thank you!
from xml.sax import make_parser
from xml.sax.handler import ContentHandler
class reportHandler(ContentHandler):
def __init__(self):
self.isReport = 0
def startElement(self, name, attrs):
if name == 'title':
self.isReport = 1
self.reportText = ''
def characters(self, ch):
if self.isReport:
self.reportText += ch
def endElement(self, name):
if name == 'title':
self.isReport = 0
print self.reportText
parser = make_parser()
parser.setContentHandler(reportHandler())
parser.parse('http://www.some.com/rss/')

Re: Splitting SAX results
Well SAX isn't the problem... maybe I should repost this with a different title. The SAX part works just as I want, but the results I get back need to be manipulated. No matter what I try I can't split a result like 'Title 1:Description' on the colon without getting an IndexError. Ideas anyone? -- http://mail.python.org/mailman/listinfo/python-list
Re: Splitting SAX results
I do know how split works, but thank you for the response. The end
result that I want is a dictionary made up of the title results coming
through SAX, looking like {'Title1: Description',
'Title2:Description'}.
The XML data looks like:
Title1:Description
Link
Desc
Author
Date
Title2:Description
Link
Desc
Author
Date
I've tried different approaches, a couple of which I've added to the
code below (only running one option at a time):
from xml.sax import make_parser
from xml.sax.handler import ContentHandler
tracker = [] # Option 1
tracker = {} # Option 2
class reportHandler(ContentHandler):
def __init__(self):
self.isReport = 0
def startElement(self, name, attrs):
if name == 'title':
self.isReport = 1
self.reportText = ''
def characters(self, ch):
if self.isReport:
self.reportText += ch
tracker.append(ch) # Option 1
key, value = ch.split (':') # Option 2
tracker[key] = value
def endElement(self, name):
if name == 'title':
self.isReport = 0
print self.reportText
parser = make_parser()
parser.setContentHandler(reportHandler())
parser.parse('http://www.some.com/rss/')
print tracker
Option 1 returns a list with the markup included, looking like:
[u'Title1:", u'\n', u'Description ', u'\n', u'\t\t\t', u'Title2:',
u'\n', u'Description ', u'\n', u'\t\t\t', etc]
Option 2 fails with the traceback:
File "C:\test.py", line 21, in characters
key, value = ch.split(':')
ValueError: need more than 1 value to unpack
Thank you for the help!

XML / Unicode / SAX question
I am using SAX to parse XML that has numeric html entities I need to
convert and feed to JavaScript as part of a CGI. I can get the
characters to print correctly, but not without being surrounded by
linebreaks:
from xml.sax import make_parser
from xml.sax.handler import ContentHandler
import htmlentitydefs, re
def unescape_charref(ref):
name = ref[2:-1]
base = 10
if name.startswith("x"):
name = name[1:]
base = 16
return unichr(int(name, base))
def replace_entities(match):
ent = match.group()
if ent[1] == "#":
return unescape_charref(ent)
repl = htmlentitydefs.name2codepoint.get(ent[1:-1])
if repl is not None:
repl = unichr(repl)
else:
repl = ent
return repl
def unescape(data):
return re.sub(r"&#?[A-Za-z0-9]+?;", replace_entities, data)
class newsHandler(ContentHandler):
def __init__(self):
self.isNews = 0
def startElement(self, name, attrs):
if name == 'title':
self.isNews = 1
def characters(self, ch):
if self.isNews:
ch = unescape(ch)
print ch
def endElement(self, name):
if name == 'title':
self.isNews = 0
parser = make_parser()
parser.setContentHandler(newsHandler())
parser.parse('http://www.some.com/rss/rss.xml')
For a line like 'Mark à Capbreton'
my results print as:
'Mark
à
Capbreton'
Is this another SAX quirk? I've already had to hack my way around SAX
not being able to split results on a colon. No matter if I try strip,
etc the results are always the same: newlines surrounding the html
entities. I'm using version 2.3.5 and need to stick to the standard
libraries. Thanks.

Re: Nested dictionaries trouble
Thank you again for the great suggestions. I have one final question
about creating a httpMonths dictionary like {'Jan':'01' , 'Feb':'02' ,
etc} with a minimal amount of typing. My code follows (using Python
2.3.4):
import calendar
# Create years list, formatting as strings
years = map(str, xrange(1990,2051))
# Create months list with three letter abbreviations
months = list(calendar.month_abbr)
# Create monthTotals dictionary with default value of zero
monthTotals = dict.fromkeys(months[1:],0)
# Create yearTotals dictionary with years for keys
# and copies of the monthTotals dictionary for values
yearTotals = dict([(year, monthTotals.copy()) for year in years])
# Create httpMonths dictionary to map month abbreviations
# to Apache numeric month representations
httpMonths =
{"Jan":"01","Feb":"02","Mar":"03","Apr":"04","May":"05","Jun":"06","Jul":"07","Aug":"08","Sep":"09","Oct":"10","Nov":"11","Dec":"12"}
It is this last step I'm referring to. I got close with:
httpMonths = {}
for month in months[1:]:
httpMonths[month] = str(len(httpMonths)+1)
but the month numbers are missing the leading zero for 01-09. Thanks!

print item.text
Whether I try this for title or link, nothing is printed. There are
also unicode characters in the tags, I'm not sure if that
could affect the output like this. In case it did I passed an encoding
argument to ET.parse (which I'd seen in other posts) but it said
encoding was an unexpected argument...
Printing all subelements does work:

Re: Simple elementtree question
Thank you very much! That did it. In the source XML tags have rdf:about attributes with the link to the story, and it was here I planned on grabbing the link and matching it up with the child text. After seeing the output of elmenttree's getiterator() though, it now looks like each item, title, description, and link is a separate element... I could use a dictionary or lists to match the first title to the first link, but is there a more elegant way in elementtree (or otherwise) to do this?

CGI and external JavaScript nightmare
My website is built from a Python CGI and works great. I'm now including Google Ads, which requires two pieces of JavaScript; the first contains the display settings for the ads, and the second piece is a very lengthy garbled js file at http://pagead2.googlesyndication.com/pagead/show_ads.js The first piece of JavaScript works fine and the ads display correctly, however the second file throws an "unterminated string literal" js error. Looking at it you can see a healthy amount of both single and double quotes, which is where my problem lies. What is the best way to get the second js file into a nice printable/ usable format? cgi.escape? xml.sax.saxutils.quoteattr? String substitution? I could use some guidance.

Re: CGI and external JavaScript nightmare
Thank you for the replies. After a lot of research I tracked down the issue. I was using the CGI to build all of the pages for the site, then filling in content with .innerHTML= as users clicked on tabs. Since I wanted to place the Google Ads in different parts of each page, the Google Ads JavaScript was in each page chunk being dynamically placed with .innerHTML. It turns out that JavaScript isn't executed when it is placed in a page via .innerHTML. I tried some tricks to execute it after it was added to the page (eval, appendChild) but it still didn't work. The Google Ads JavaScript is very touchy and their agreement is very strict; it wasn't even clear that what I was doing was in line with it, so I broke the site up into multiple CGI pages and now it works fine. One CGI question - since all of my CGIs are spitting out HTML is their source code safe? wget and linking to the source deliver the output HTML. Are there any other methods of trying to steal the source CGI I need to protect against? Thank you. -- http://mail.python.org/mailman/listinfo/python-list

The Google Ads JavaScript is very touchy and their agreement is very strict; it wasn't even clear that what I was doing was in line with it, so I broke the site up into multiple CGI pages and now it works fine. One CGI question - since all of my CGIs are spitting out HTML is their source code safe? wget and linking to the source deliver the output HTML. Are there any other methods of trying to steal the source CGI I need to protect against? Thank you. -- http://mail.python.org/mailman/listinfo/python-list
Re: CGI and external JavaScript nightmare
Thank you for the replies. After a lot of research I tracked down the issue. I was using the CGI to build all of the pages for the site, then filling in content with .innerHTML= as users clicked on tabs. Since I wanted to place the Google Ads in different parts of each page, the Google Ads JavaScript was in each page chunk being dynamically placed with .innerHTML. It turns out that JavaScript isn't executed when it is placed in a page via .innerHTML, it is inserted as text hence the unterminated string literal error.

I'm on a shared server (Dreamhost). The CGI itself has 755 permissions to execute, but what about folder permissions, etc? If you could expand on "access to the server, and so on" that would be great. -- http://mail.python.org/mailman/listinfo/python-list
Regexp not performing the same in FTP versus Python
Hello all,
I'm trying to use a regular expression in an FTP script to list
certain files. When run in a standard FTP session the command:
dir .??[oOdDnNmM]*
returns 48 files. When I use the following Python script it prints
roughly 12 files (a subset of the 48), ending with 'None':
import ftplib, traceback
ftp = ftplib.FTP('host')
ftp.login(user='user', passwd='pass')
try:
admFiles = ftp.dir('.??[oOdDnNmM]*')
print admFiles
except:
traceback.print_exc
ftp.quit()
Is my Python syntax off?
Thank you.

Re: Regexp not performing the same in FTP versus Python
It's strange but since more files have been added to this directory the regexp appears to be working correctly. Sorry to bother the list and thanks for your time. Ian -- http://mail.python.org/mailman/listinfo/python-list
