For a non-regular-expression solution
you might consider something simlar to
the following
s = '''\

2.E+00 2.31616E-05 0.0017
5.E+00 2.42717E-05 0.0017
total 1.93417E-04 0.0012'''
l1 = s.split( '\n' )
l2 = [ ]
for this_row in l1[ : -1 ] :
temp = this_row.strip().split()
l2.append( [ float( x ) for x in temp ] )
last = l1[ -1 ].strip().split()[ 1 : ]
l2.append( [ float( x ) for x in last ] )
print
for this_row in l2 :
if len( this_row ) > 2 :
x , y , z = this_row
print '%5.4e %5.4e %5.4e ' % ( x , y , z )
else :
x , y = this_row

John
Thanks for posting your solution to Dave McCormick's query
about colorizing text
I was not familiar with the re.finditer method
for searching strings or with using tags in
Tkinter Text widgets to change text attributes
Instead of binding the Text widget to events
to call the colorizer on each key-stroke, I used a button
callback
http://cl1p.net/cs_static_text_color
This provides a static one-shot colorization after all
of the text is entered and should save a few cpu cycles
although it's not as nifty as the dynamic process
I used a dictionary instead of a list for position data
and also added a { term : color } dictionary so that
words other than color names can be hi-lighted

SQLite3__Python2.3-SQLite__Problem
It's been almost 2 years since I've done anything with Python and SQLite and I'm having some problems that I don't recall from my last usage It seems that SQLite3 data bases created at the command line and those created using the sqlite module from within Python are no longer compatible with each other using the setup that I now have I thought I remembered that the data bases created either way were always 100% transparent with each other and that I could use an SQLite3 data base either from the command line or from within Python without any problems at all I did a fair amount of Google-izing looking for related problems but didn't have much success I did find one entry in the Debian Bug Tracking System that had some discussions about SQLite3 & Python-SQLite versioning but the original errors mentioned didn't seem to be of the same nature as what i'm seeing here === Operating System Debian GNU/Linux Sarge python2.3 ...

I did re-build the data bases from the command line
using sqlite3 instead of using the older ones
from a couple of years back which I wasn't sure
were sqlite2 or sqlite3
It seems that the older Debian Sarge version
of the python2.3-sqlite package is the one
that isn't directly compatible with sqlite3 dbs
created at the command line
I downloaded the PySQLite2 source package
and compiled and installed it using distutils
Now everything is also working fine under Debian Sarge
and the dbs are OK either from the command line or from
within Python
Thanks a lot for taking the time to help

python-mysqldb__debian_to_freebsd
Greetings I'm using a commercial web host running FreeBSD that fortunately has Python and MySQL, but no python-mysqldb module Before begging the host to install it I thought I would try the Debian version that I have on the outside chance that it might fly directly under FreeBSD on the server import MySQLdb leads to the ImportError message Shared object "libpthread.so.0" not found, required by "_mysql.so" On my local Debian installation the reference to that particular library file is actually a symbolic link libpthread.so.0 -> libpthread-0.10.so I copied libpthread-0.10.so over to the server in a directory that is in the Python search path and renamed it to libpthread.so.0 I tried to make the symbolic link as above from Python since I don't have a shell account, but it failed for some reason that I don't recall at the moment After a bit of google-izing and a quick scan of the MySQL install docs, I also set the LD_LIBRARY_PATH enviroment variable to point to the dir where the supposed missing file lives Is there any at all chance that this will work with the proper configs or should I go ahead and beg the host for an installation ?

As a method to list the numbers that have been input
and avoid having to know in advance how many numbers
are needed, you might consider a simple input mode
where a character other than an integer is input
as a stop-input-mode character
print '\nInput an integer at the > prompt \n'
print 'Enter a period . to end input mode'
print 'and begin processing \n'
prompt = '> '
period = '.'
list_input = [ ]
while True :
this_str = raw_input( prompt )
if this_str == period :
break
try :
list_input.append( int( this_str ) )
except :
print '\nInput Must be an Integer'
print 'or a period . to exit Input Mode \n'
num_entries = len( list_input )
print 'Input List \n'
for this_item in list_input :
print '%s' % this_item

Re: any Python equivalent of Math::Polynomial::Solve?
Alex Thanks for posting your generalized numarray eigenvalue solution It's been almost 30 years since I've looked at any characteristic equation, eigenvalue, eignevector type of processing and at this point I don't recall many of the particulars Not being sure about the nature of the monic( p ) function, I implemented it as an element-wise division of each of the coefficients Is this anywhere near the correct interpretation for monic( p ) ? Using the version below, Python complained about the line . M[ -1 , : ] = -p[ : -1 ] So, in view of you comments about slicing in you follow-up, I tried without the slicing on the right .. M[ -1 , : ] = -p[ -1 ] The following code will run and produce results, but I'm wondering if I've totally screwed it up since the results I obtain are different from those obtained from the specific 5th order Numeric solution previously posted here . from numarray import * . . import numarray.linear_algebra as LA . . def monic( this_list ) : . . m = [ ] . . last_item = this_list[ -1 ] . . for this_item in this_list : . . m.append( this_item / last_item ) . . return m . . . def roots( p ) : . . p = monic( p ) . . n = len( p ) # degree of polynomial . . z = zeros( ( n , n ) ) . .

I extended the VueJS CLI to allow me get a *Django* project with VueJS up and running for any project or my next hackathon project with one command. https://github.com/NdagiStanley/vue-django I was impressed by the manner in which the Github stars increased in the forked repo and judging that it was of value to other devs besides myself, I'd appreciate your views in terms of possible features, other use-cases this can extend to and what I can think about doing :) Collaboration, Advice -- https://mail.python.org/mailman/listinfo/python-list

I added the following code to your example
to unpack planet.value into mass and radius
after first importing Enum
from enum import Enum
def test_01() :
print( '\n planet mass radius gravity \n' )
for planet in Planet :
mass , radius = planet.value
print( ' {:8s} {:9.4E} {:9.4E} {:9.4E} '.format( planet.name , mass
, radius ,
planet.surface_gravity ) )
if __name__ == '__main__' :
test_01()

Parsing Nested List
I am trying to parse a Python nested list that is the result of the
getOutlines() function of module PyPFD2 using pyparsing module. This is the
result I get. what in the world are 'expandtabs' and why is that making a
difference to my parse attempt?
Python Code
7
import PPDF2,pyparsing
from pyparsing import Word, alphas, nums
pdfFileObj=open('x.pdf','rb')
pdfReader=PyPDF2.PdfFileReader(pdfFileObj)
List=pdfReader.getOutlines()
myparser = Word( alphas ) + Word(nums, exact=2) +"of" + Word(nums, exact=2)
myparser.parseString(List)
This is the error I get:
Traceback (most recent call last):
File "", line 1, in
myparser.parseString(List)
File "C:\python\lib\site-packages\pyparsing.py", line 1620, in parseString
instring = instring.expandtabs()
AttributeError: 'list' object has no attribute 'expandtabs'
Thanks so much, not getting any helpful responses from https://python-forum.io.

Thank you so much Steve. I do seem to be barking up the wrong tree. The
result of running getOutlines() is indeed a nested list: it is the pdfs
bookmarks. There are 3 levels: level 1 is the section from A-F. When a section
there are exhibits, so in Section A we have exhibits 1A to nA. Finally there
are bookmarks for individual pages in an exhibit. So we have this for Section
A:
[{'/Title': 'Section A. Payment Documents/Decisions', '/Page':
IndirectObject(1, 0), '/Type': '/FitB'}, [{'/Title': '1A: Disability
Determination Transmittal (831) Dec. Dt.: 05/27/2016 (1 page)', '/Page':
IndirectObject(1, 0), '/Type': '/FitB'}, [{'/Title': '1A (Page 1 of 1)',
'/Page': IndirectObject(1, 0), '/Type': '/FitB'}], {'/Title': '2A: Disability

IndirectObject(6, 0), '/Type': '/FitB'}, [{'/Title': '2A (Page 1 of 10)',

I have found that I can use the index values in the list to print out the
section I need. So print(MyList[7]) get me to section f taht I want.
print(MyList[9][1]) for example give me a string that is the bookmark entry for
Exhibit 1F. But this index value would presumeably be different for each pdf
file - that is there may not always be Section A-E, but there will always be a
Section F. In ther words, the index values that get me to the right section
would be different in each pdf file.

Extracting data from ython dictionary object
I am new to Python. I am trying to extract text from the bookmarks in a PDF
file that would provide the data for a Word template merge. I have gotten down
to a string of text pulled out of the list object that I got from using PyPDF2
module. I am stuck on now to get the data out of the string that I need. I am
calling it a string, but Python is recognizing as a dictionary object.
Here is the string:
{'/Title': '1F: Progress Notes Src.: MILANI, JOHN C Tmt. Dt.: 05/12/2014 -
05/28/2014 (9 pages)', '/Page': IndirectObject(465, 0), '/Type': '/FitB'}
What a want is the following to end up as fields on my Word template merge:
MedSourceFirstName: "John"
MedSourceLastName: "Milani"
MedSourceLastTreatment: "05/28/2014"
If I use keys() on the dictionary I get this:
['/Title', '/Page', '/Type']I was hoping "Src" and Tmt Dt." would be treated as
keys. Seems like the key/value pair of a dictionary would translate nicely to
fieldname and fielddata for a Word document merge. Here is my code so far.
[python]import PyPDF2
pdfFileObj=open('x.pdf','rb')
pdfReader=PyPDF2.PdfFileReader(pdfFileObj)
MyList=pdfReader.getOutlines()
MyDict=(MyList[-1][0])
print(isinstance(MyDict,dict))
print(MyDict)
print(list(MyDict.keys()))[/python]
I get this output in Sublime Text:
True
{'/Title': '1F: Progress Notes Src.: MILANI, JOHN C Tmt. Dt.: 05/12/2014 -
05/28/2014 (9 pages)', '/Page': IndirectObject(465, 0), '/Type': '/FitB'}
['/Title', '/Page', '/Type']
[Finished in 0.4s]
Thank you in advance for any suggestions.

Thanks for your response. Nice to know I am at least on the right path.
Sounds like I am going to have to did in to Regex to get at the test I want.

Thanks you Lawrence for your response. Sounds like I am going to have to dig in
