error with Firefox Binary 'The browser appears to have exited'
I have problem with selenium and Firefox when i run my code below:
from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from bs4 import BeautifulSoup
import urllib2,cookielib
import re
from pyvirtualdisplay import Display
import urllib
import urllib2
import httplib2
from os import system
display = Display(visible=0, size=(800, 600))
display.start()
name = 'test'
driver = webdriver.Firefox()
driver.get("http://example.com";)
driver.switch_to_default_content()
inputElement = driver.find_element_by_name("name")
inputElement.send_keys(name)
inputElement.submit()
print "Please wait for 5s to get results.."
content = driver.page_source.encode("utf-8")
html = str(content)
soup = BeautifulSoup(html)
print soup
display.stop()
driver.close()
And i get this error:

again it show me the above error.
I have Python2.7 .
I hope someone help me.

Re: [newbie questions] if conditions - if isset - if empty
Thanks ChrisA a lot.
I just tried what you said, but I got an error, here's what I tried :
item['name'] = hxs.select('//div[@id="center-main"]/h1/text()').extract()[0]
author_brand = re.match(r'^[.*] - (.*)$', item['name'], re.I|re.S|re.M)
item['author_brand'] = author_brand.group(2) if type(author_brand) != None
else ''
And I'm getting the following error :
AttributeError: 'NoneType' object has no attribute 'group'
Thanks again :)

[newbie questions] if conditions - if isset - if empty
Hello, I'm coming from PHP background ant totally new to Python, I just started using scrapy, but has some generic question in python. 1. How can I write the following code in easier way in Python ? if len(item['description']) > 0: item['description'] = item['description'][0] else: item['description'] = '' In PHP I can write it as follows : $item['description'] = (len(item['description']) > 0) ? item['description'][0] : ''; So, is there similar way in Python ? 2. How can I check if this variable defined or not, in PHP I can use isset();, in other way, how can I make the following syntax in Python ? $variable = isset($array['element']) ? true : false; Thanks a lot, Mahmoud -- http://mail.python.org/mailman/listinfo/python-list

Re: creating my own logwatch in python
A few code critiques: - Your code is not very help friendly because it can not be run, so I have to deadlist debug it. - There are various syntax errors in the code: - for example: file is not defined when you invoke tail(file) - You are overshadowing a built-in type 'file' by that name, which is confusing. PEP 8 states that if you want to use a keyword, the practice is to put an underscore after it. So, it should become file_ - Getopt is very old and should not be used. You should use the better, readable, optparse - That while loop will consume 99% CPU because of the infinite loop - line = file.readline() is guaranteed to return a newline OR an empty string ONLY when an EOF is encountered since you're not specifying the optional maximum read byte size. This means that all your characters are strings. So, why do you explicitly convert each character to a string and separate each character by a space? (line 18) - Line 19 will always return 0 because of line 18 - Line 19->22 are completely redundant, since readline is guaranteed to give you ONE line. You should just do if "uccess" in logString: ...

Re: proposal: add setresuid() system call to python
Why don't you write a python extension module?

A multi-threaded file searcher for processing large text files
the worker threads should set the stop conditions. A glaring hole leading from this is if the blocking_timeout is set to something like 1second and by the time a user attempts to iterate over the results, the worker threads will prematurely stop processing. Speaking of stop processing, should self._stop_processing be a conditional variable. Right now it's a boolean, and I think that's pretty hacky. I don't like the StopIteration stop condition, maybe someone has a better suggestion? A future modification I'm looking for is to launch multiple threads that process different parts of the file (different chunks) and return their results, probably indexed by their chunk offset. Then I can iterate over that sequentially. I think that would be a trivial parallel optimization. Thoughts? Comments?

Re: one-time factory in python for an experienced java guy
What Paul was trying to elaborate on is that have your customers or whomever will use this implement their own generator protocol to generate whatever number format they need. Paul just gave you an example with itertools.count(), where it is an infinite generator that yields count+1 every time. Read up on the iterator protocol, have your customers pass in a generator to establish their own formats. http://docs.python.org/library/stdtypes.html#iterator-types This is much more elegant than AbstractCustomerRandomFormatGenerator..etc which is what the reference to "erase everything from Java" is attempting to relate. -- mahmoud mack abdelkader python powered http://blog.mahmoudimus.com/ mahm...@linux.com On Tue, Jul 14, 2009 at 10:55 AM, phonky wrote: > Thanks Paul, > > Ugh, just forget everything you ever knew about java.
