I need to execute a script in the background through a service. The service kicks off the script using Popen. p = Popen('/path/to/script/script.py', shell=True) Why doesn't the following script work when I include the file writes in the for loop? #!/usr/bin/python import os import time def run(): fd = open('/home/dilleyjrr/tes...
I need a function to determine if a directory is a mount point for a drive. I found this code already which works well for linux: def getmount(path): path = os.path.abspath(path) while path != os.path.sep: if os.path.ismount(path): return path path = os.path.abspath(os.path.join(path, os.pardir)) return path But I'...
So, I wanted to extend the Python smtpd SMTPServer class so that it could handle SMTP AUTH connections. Seemed simple enough... So, it looked like I could just start like this: def smtp_EHLO(self, arg): print 'got in arg: ', arg # do stuff here... But for some reason, that never gets called. The Python smtpd library calls o...
I'm trying to use regular expression right now and I'm really confuse. I want to make some validation with this regular expression : ^[A-Za-z0-9_.][A-Za-z0-9_ ]* I want to make it so there is a limit of character (32) and I want to "match" all the string. ex: string : ".hello hello" -this should work string : ".hello hello /.." -T...
I am parsing some XML with the elementtree.parse() function. It works, except for some utf-8 characters(single byte character above 128). I see that the default parser is XMLTreeBuilder which is based on expat. Is there an alternative parser that I can use that may be less strict and allow utf-8 characters? This is the error I'm gett...
When trying to render a Django template file in Google App Engine from google.appengine.ext.webapp import template templatepath = os.path.join(os.path.dirname(file), 'template.html') self.response.out.write (template.render( templatepath , template_values)) I come across the following error: <type 'exceptions.UnicodeD...
Does anyone know the simplest way to import an OpenSSL RSA private/public key (using a passphrase) with a Python library and use it to decrypt a message. I've taken a look at ezPyCrypto, but can't seem to get it to recognise an OpenSSL RSA key, I've tried importing a key with importKey as follows: key.importKey(myKey, passphrase='PASS...
This is what I'm trying to do in Python: class BaseClass: def __init__(self): print 'The base class constructor ran!' self.__test = 42 class ChildClass(BaseClass): def __init__(self): print 'The child class constructor ran!' BaseClass.__init__(self) def doSomething(self): print 'Test is: ', self.__test test = ChildClass() tes...

In other languages I can obtain the current frame via a reflection api to determine what variables are local to the scope that I an currently in. Is there a way to do this in Python? ...
I have some data in CSV format that I want to pull into an Excel spreadsheet and then create some standard set of graphs for. Since the data is originally generated in a Python app, I was hoping to simply extend the app so that it could do all the post processing and I wouldn't have to do it by hand. Is there an easy interface with Pytho...
I'm looking for a quick way to get an http response code from a url (i.e. 200, 404, etc). Not sure which library to use. Thanks ...
Lately, I tried to set local variables from outside of a running generator. The generator code also should access these variables. One trouble was, that when accessing the variables, it seamed that the interpreter was thinking it must be a global since the variable was not set in the local scope. But I don't wanted to change the global ...
Hi, I am trying to parse XML with Python but not getting very far. I think it's due to wrong XML tree this API returns. So this is what is returned by the GET request: <codigo>3</codigo><valor></valor><operador>Dummy</operador> The GET request goes here: http://69.36.9.147:8090/clientes/SMS_API_OUT.jsp?codigo=ABCDEFGH&cliente=XX...
I wrote: Object result = (Object)client.execute("method",params); in java client. Actually, the result should be printed in string format. But I can only output the address of "Object result", how can I get the content? And I have tried String result = (String)client.execute("method",params); It says lang.until.Object can not cast ...
I realize this is a broad topic, but I'm looking for a good primer on parsing meaning from text, ideally in Python. As an example of what I'm looking to do, if a user makes a blog post like: "Manny Ramirez makes his return for the Dodgers today against the Houston Astros", what's a light-weight/ easy way of getting the nouns out of a s...
I have some code in a python string that contains extraneous empty lines. I would like to remove all empty lines from the string. What's the most pythonic way to do this? Note: I'm not looking for a general code re-formatter, just a quick one or two-liner. Thanks! ...
I'm trying to implement dynamic reloading objects in Python, that reflect code changes live. Modules reloading is working, but I have to recreate every instance of the modules' classes for changes to become effective. The problem is that objects data (objects __dict__ content) is lost during the process. So I tried another approach: ...
Python 3.x renamed the low-level module 'thread' to '_thread' -- I don't see why in the documentation. Does anyone know? ...
