Re: [Tutor] Using Python and Regex
Thanks for yoru reply. This was my first attempt,when running through idleid
get the following error:-
Traceback (most recent call last):

27, in

File "C:\Users\Bill\Desktop\TXT_Output\email_extraction_script.py", line
20, in traverse_dirs
if match:
UnboundLocalError: local variable 'match' referenced before assignment
My code is as follows:
import os
import datetime
import re
now = datetime.datetime.now()
timestamp = now.strftime('%d-%m-%Y')
output_file = open('OUTPUT - ' + timestamp + '.csv', 'w+')
def traverse_dirs(wdir):
grabline = 0
for f in os.listdir('.'):
if os.path.isfile(f) == True:
if "Email Exceeded Maximum Size Limit" in f:
continue
else:
content = open(f)
lines = content.readlines()
for line in lines:
match =
re.search(r"\b[^\<][A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}[^\>]\b",l
ine)
if match:
print(match.group(0))
otext = match.group(0) + ",\n"
output_file.write(otext)
if __name__ == "__main__":
working_dir = 'C:\\Users\\Jono\\Desktop\\TXT_Output\\'

Subject: [Tutor] Using Python and Regex
Hi,
I'm relatively new to Python and I'm trying to write a script to iterate
through a series of text files in folder searching for some specific text
and write it to a CSV.
I plan to use Regex to match the text and I have already identified the
Regex to do this. I've also got as far as creating a CSV using python but,
being new to this, I'm looking for some pointers on how to traverse through
the folder and open each file in turn to check the content for matches using
Regex.
Any advice would be gratefully received.
Regards
Bill

The indentation of 'if match' is wrong; the way you wrote the line will be
executed after the for loop, but you want it inside the loop.
You are lucky that the first file you encountered was empty and thus the
match variable never set ;) Otherwise the error would have been harder to
find.
Random remarks:
> def traverse_dirs(wdir):
> grabline = 0
> for f in os.listdir('.'):
The listdir() argument should probably be wdir instead of '.'.
> if os.path.isfile(f) == True:
The idiomatic way to spell this is
if os.path.isfile(f):
> content = open(f)
> lines = content.readlines()
> for line in lines:
The readlines() call will put the whole file into a potentially huge list.
You don't need to do this for your application. Instead iterate over the
file directly:
content = open(f)
for line in content:
That keeps memory consumption low and the data processing can start
immediately.
PS: The way you wrote it your program will process a single directory. If
you want to look into subdirectories you should read up on os.walk() as
already suggested. You will end up with something like
for path, dirs, files in os.walk(wdir):
for name in files:
f = os.path.join(path, name)
content = open(f)
...

continue
Note that this checks whether the string is in the file *name*.
It does not test if the string is in the file content.
Is that really what you want?

Re: [Tutor] Error message
Hi Richard, I would recommend asking the PyGame folks on this one. What you're running into is specific to that external library, and folks who work with PyGame have encountered the problem before: they'll know how to diagnose and correct it. For example: http://stackoverflow.com/questions/7775948/no-matching-architecture-in-universal-wrapper-when-importing-pygame http://stackoverflow.com/questions/8275808/installing-pygame-for-mac-os-x-10-6-8 What appears to be happening is a 32-bit vs 64-bit issue: you may have installed a version of PyGame for one architecture, but should have chosen the other. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
[Tutor] IndentationError
Dear Python Users, Attachment is python code. The function of this code is that I want to insert lots of fiber into matrix, data is a list storing translate vector. When a fiber is translated to matrix, I used fiber to cut matrix. So the new part will be generated, I delete the previous part and resume fiber. The loop will stop when all fibers are inserted to matrix. I used abaqus 6.11 to run fibermatrix.py, but it has problems. Thank you for your help.

Like the subject says, you have multiple indentation errors.
If you want further help I suggest you tell us what "problems"
you get - including full error messages.
Also if you can reduce your code to something more readable
that will help.
Also...
from part import *
from material import *
the import * style of import can lead to problems with
name clashes - with the last imported name masking
all others. This is doubly true when you have so as many
imports as you do, the likelihood of a name being used
twice is quite high.
Finally, I don't recognise any of the modules you are
importing, I assume they are from some specialist library
or other. In particular you seem to be referencing
something called mdb but that does not appear as a module
or variable in your code, so its impossible for us to
tell what it is. (Presumably its imported as one of
the * names but we have no clue which module it comes
from!) You could maybe try asking for help on that
library's support forum if the error proves to be
library related.
