Still seems rather harsh to me... After all, one of the common
suggestions for solving a maze is to "always follow [right/left] hand" (put
said hand on said wall -- walk keeping that hand in contact with the wall
-- if you hit a dead end, the 180 turn-around will pick up the other wall
and carry our around the branch that lead to that dead-end). But you are
postulating "hit a dead end, through out all progress, start over"

Is "userTurtle" being guided by a real user? If so, resetting to the
start on each dead-end is a major penalty, the user should have the option
of back-tracking and picking another turn.

If "userTurtle" is a separate algorithm it should still have a
back-track ability. The difference is whether the algorithm uses a wall
following scheme, or a random direction at any intersection. Note that,
without memorizing choices for each intersection, the random direction mode
can result in repeating a failed path.

I don't think including this was a smart move. It risks turning this
totally unrelated thread into a Nikos-like thread. I don't think
baujacob did anything that deserves that his question will be used
as an opportunity to have a jab at Nikos which may turn this thread
into something totally unhelpful for baujacob himself.

returning the user to the start is a simple case of resetting the user's
coordinates.

unless you are referring to a true turtle in a physical maze in which
case your requirement is probably not a good idea (What happens if you
bump a wall on your way back)

more details of the exact scenario may enable some more pointers in the
right direction.

He's a troll, sometimes goes by the name "Ferrous Cranus", and he
really isn't worth polluting this thread about. Search python-list
archives for superhost.gr (his web site - be aware that he and it are
Greek, so some of his error messages and such are non-ASCII) and have
a read. Unfortunately he manages to drive a number of people to
frustration, which results in bad blood and spiralling unpleasantness,
which sometimes spills over into other threads, like this.

What we really should do is use multiple processes of conversation,
instead of threads. That way, if one goes rogue, it can't affect
memory used by other conversations...

He is the lists help vampire. He comes to the list when his programs
break and insists that we help him out. Advise to read up on a
particular subject is generally ignored as are links that explain what
is going on. When a correction is offered, he often enough rejects it
because it is somehow too many lines or such reasons. When he finnaly
accept a correction, that often enough reveals a new bug and the
cycle restarts.

I have some experience working with the above project, and am willing to
assist. Please join us on the developer discussion forum for the code,
<URL:http://lists.alioth.debian.org/mailman/listinfo/python-lockfile-devel>.

In my opinion, we *really* need someone to become the domain expert for

It's close. I think you're overthinking it. Take it step by step. Decode,
process, encode. That means convert the inputs to integers, add the
integers, convert the result back.

def add(c1, c2):
% Decode
c1 = ord(c1) - 65
c2 = ord(c2) - 65
% Process
i1 = (c1 + c2) % 26
% Encode
return chr(i1+65)

Or, as a one-liner:

A = ord('A')
def add(c1, c2):
return chr((ord(c1)-A + ord(c2)-A) % 26 + A)

Python uses # for comments, not %, as I'm sure you know. What language

Hi guys,

I'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.

So far, I've been able to do this, to search for individual strings:

[code]import re

shakes = open("output.csv", "r")

for line in shakes:
if re.match("STRING", line):
print line,[/code]

How can I change this to input the strings to be searched from another file?

So far I haven't been able to.

Thanks for the ideas.

Assuming every line in input.txt contains a regular expression and you don't
care which one matches:

shakes = open("output.csv")

# you will iterate over the regex multiple times,
# so put them in a list
rattles = [line.strip() for line in open("input.txt")]

for line in shakes:
for expr in rattles:
if re.match(expr, line):
print line,
break # out of the for-rattles loop
# at the first matching regex

Take your existing code, and make the bulk of it into a function
definition. The function should take the 'string' as a parameter.

Once you've got that debugged, you can write code that reads your
pattern file, and for each line of it, calls the function you just
wrote.

You can certainly do it the way Peter describes, but if you learn to
factor each problem into separate functions (or classes, or generator,
or decorator, or ...) then your code will be easier to test, easier to
understand, and easier to reuse.

Hi,

I'm working on a python project for protocol testing.I need to provide only python compiled source to our customer.

Here are the steps followed to take python compiled from actual source.
1.There are 5 different test suites under the project
2..Run all 5  test suite with python sources.
3.After completion of test suite ,just take .pyc files and copied in to seperate folder.
4.Re run test suite for any issues with the .pyc code.I started seeing one issue when it logs the test results in to excel file.
 This issue occurs sometimes.50% of chances are there to see this issue

Below is the error
Traceback (most recent call last):
  File "D:\users\ScriptTestCode\scriptsCompiledCode\ExecuteScripts.py", line 32, in <module>
    TestManager.execute_scripts(TEST_BUILD)
  File "D:\users\ScriptTestCode\scriptsCompiledCode\TestManager.py", line 764, in execute_scripts
  File "D:\users\ScriptTestCode\scriptsCompiledCode\TestManager.py", line 772, in _execute_all
  File "D:\users\ScriptTestCode\scriptsCompiledCode\TestManager.py", line 924, in _testsuite_950_band
  File "D:\users\ScriptTestCode\scriptsCompiledCode\TestManager.py", line 377, in exec_test_suite
  File "D:\users\ScriptTestCode\scripts\ResultReporter.py", line 321, in save_test_results
    _my_doc.save(StackTestData.TEST_REPORT_PATH)
  File "C:\Python27\lib\site-packages\pyExcelerator\Workbook.py", line 610, in save
    doc.save(filename, self.get_biff_data())
  File "C:\Python27\lib\site-packages\pyExcelerator\CompoundDoc.py", line 554, in save
    f = file(filename, 'wb')
IOError: [Errno 22] invalid mode ('wb') or filename: '.\\TestResults\\TestReport.xls'

Now my question is of there any issue with logging to excel it should happen for the first test suite itself,but it occurs in either 2,3,4 or 5 test suite. Some it runs without any issues.

Please let me know do i need to follow any sequence when copying  compiled source code and  whats exactly going wrong here.

Best Regards,
Chandan.

Well, the fact that it works/fails 50% of the time points to a race
condition. You don't say how the test suites / tests are running, but if
anything's running in parallel, one test's cleanup could be pulling the
file out from under another test's writing results. Without knowing more
about your test runner, this is really guess-work.

Logging to Excel isn't part of the builtin logging module so you've
presumably added that functionality yourself. But PyExcelerator is
ultimately just opening a file and writing to it so for this purpose it
appears to be equivalent to, say, logging a bunch of stuff into a list
and then writing that into a file.

Hi,
Yes ,its not actual logging module.Using pyexcelerator we are storing just test results to excel file.
Each test suite has some 25-100 test cases.We are using unit test from python ,after completion of each test case the test result will be stored in excel file.Below is the sample result that is stored in excel file.

S.No   TestCaseID   TestDescription    TestResult 
1         Test_case_1 SetTransmitPower  Pass
2         Test_case_2 Set  Frequency        fail


Nothing is running parallel.

Well, the
fact that it works/fails 50% of the time points to a race
condition. You don't say how the test
suites / tests are running, but if
anything's running in parallel, one
test's cleanup could be pulling the
file
out from under another test's writing results. Without
knowing more
about your test runner, this is
really guess-work.

Logging
to Excel isn't part of the builtin logging module so
you've
presumably added that
functionality yourself. But PyExcelerator is
ultimately just opening a file and writing to
it so for this purpose it
appears to be
equivalent to, say, logging a bunch of stuff into a list
and then writing that into a file.

Sorry -- I didn't look closely enough at the error message. "invalid
mode or filename" wouldn't be the result of a file getting deleted out
from under a write.

Error 22 is returned from the MS runtime as EINVAL. It's not clear from
the traceback why it would consider that path invalid, but you're going
to have to do some legwork to narrow it down, I'm afraid.

The most likely prospects is that you're not running in the directory
you think you're in. Try putting a "print os.getcwd()" somewhere in the
mix to see where you actually are.

However, that still wouldn't quite explain why it occurs only sometimes
but, as I said, we'd have to know more about your test-runner to be able
to help.

Logging to excel is probably a wrong thing to do (it is not a good idea
to tie yourself into a 3rd party format that can be changed any time)

you would be better to log to a csv file which can then be opened by
excell OR ANY OTHER spreadsheet application.

it is also far easier to use the CSV module than attempting to write a
native XLS file

One more thing to be said for perl:

I remember when some colleague first told me about perl (I guess early 90s) I was incredulous that the *same* language could run on DOS and on Unix unchanged.
Yeah in principle we all talked about portability however in practice, we found that the only program that would run on all systems was the asymptotic null C program:
main() {;}

So a full scale language whose programs ran unchanged on all systems was BIG back then.

That we take it for granted today indicates the shoulders of the giants we are standing on.

OK

My first observation is that "maze" could be an array of "rooms" each of
which starts life with 4 exits.

Generating the maze would involve turning exits into walls.

You could create a set maze, or you could randomly generate a maze at the
start of each "game".

Once you have created a maze, define your start and end points.

If you want to apply your logic, then if the "solver" turtle enters a
"room" with only one exit, it is in a dead end.

The "solver" turtle would probably need to store which paths led to dead
ends to ensure it did not follow them again. This extends back to any
exit that only leads to dead ends.

Let's consider a simple maze, 2x2 so 4 rooms. Room 0 is the top left (nw)
room, and rooms are numbered across, down. Each room number has 4 exit
directions, nesw. 'x' is an external exit, a number is an internal room,
None is no exit (ie a wall).

maze = { 0: { 'n': 'x', 'e': 1, 's': None, w: None },
1: { 'n': None, 'e': None, 's': 3, w: 0 },
2: { 'n': None, 'e': 3, 's': 'x', w: None },
3: { 'n': 1, 'e': None, 's': None, w: 2 } }

Room 0 (nw) has an exit (or entrance) to the north and an internal path
to the east (rm 1).

Room 1 (ne) has internal paths to the west (rm 0) and south (rm 3).

Room 2 (sw) has an entrance (or exit) to the south and an internal path
to the east (rm 3).

Room 3 (se) has internal links to the north (rm 1) and west (rm 2).

The data structure shown (a dictionary of dictionaries) is just one way
of holding the maze data, and perhaps not the most elegant. The maze
could be stored as a dictionary of tuples thus:

maze = { 0: ( 'x', 1, None, None ),
1: ( None, None, 3, 0 ),
2: ( None, 3, 'x', None ),
3: ( 1, None, None, 2 ) }

Drawing such a maze graphically would require allocating co-ordinates in
some drawing space to the vertices of each room, and drawing lines along
the edges that represent walls.

Navigating such a maze graphically would require allocating co-ordinates
in the same drawing space to the centres of the rooms, and moving between
adjacent room centres provided the exit was "open".

I'm trying to port reportlab extensions to Python 3.3. On windows I get a

this doesn't happen if I run the installed Python-3.3 directly eg

is this a bug or some misconfiguration; should I be using virtualenv?

seems that venv doesn't copy the standard Libs directory into the virtual
environment; if I do that by hand then I get a proper working virtual
environment. Also seems fairly half baked to change the name bin to Scripts, but
perhaps there's some windows centric reason for that even though the Scripts dir
ends up with a lot of dlls & pyds in it. I suppose that ps1 files are in fact
scripts.
