I have a python web application that needs to launch a long running process. The catch is I don't want it to wait around for the process to finish. Just launch and finish.
I'm running on windows XP, and the web app is running under IIS (if that matters).
So far I tried popen but that didn't seem to work.
(Using python 3.2 currently)
I need to be able to:
Run a command using subprocess
Both stdout/stderr of that command need be printed to the terminal in real-time (it doesn't matter if they both come out on stdout or stderr or whatever
At the same time, I need a way to know if the command printed anything to stderr (and preferably what it printed).
I've played around with subprocess pipes as well as doing strange pipe redirects in bash, as well as using tee, but as of yet haven't found anything that would work. Is this something that's possible?
I have a following string - "AACCGGTTT" (alphabet is ["A","G","C","T"]). I would like to generate all strings that differ from the original in any two positions i.e.
GAGCGGTTT
^ ^
TATCGGTTT
^ ^
How can I do it in Python?
I have only brute force solution (it is working):
generate all strings on a given alphabet with the same length
append strings that have 2 mismatches with a given string
However, could you suggest more efficient way to do so?
hi;
i need grab to internet explorer address bar. how to get address bar url for python ? (i need second part other browsers grabbing address bar but internet explorer is urgently).
Thanks.
Python
params = urllib.parse.urlencode({'spam': '1', 'eggs': '2', 'bacon': '3'})
binary_data = params.encode('utf-8')
reg = urllib.request.Request("http://www.abc.com/abc/smart/ap/request/",binary_data)
reg.add_header('Content-Type','application/x-www-form-urlencoded')
f = urllib.request.urlopen(reg)
print(f.read())
PHP
if($_SERVER['REQUEST_METHOD'] == 'POST') {
//parse_str($_SERVER['QUERY_STRING']);
var_dump($_SERVER['QUERY_STRING']);
}
When i try print binary_data , it does show the parameter but by the time it reaches the PHP , i see nothing.
Any idea?

#this looks for words in dictionary that begin with 'in' and the suffix is a real word
wordlist = [line.strip() for line in open('/usr/share/dict/words')]
newlist = []
for word in wordlist:
if word.startswith("in"):
newlist.append(word)
for word in newlist:
word = word.split('in')
print newlist
how would I get the program to remove the string "in" from all the words that it starts with? right now it does not work
I'm looking for a quick bash script or program that will allow me to kick off a python script in a separate thread. What's the best way to do this? I know this is incredibly simple, just curious if there's a preferred way to do it.
Hello,
I'm trying to start an application using Python. I've seen that some people use startfile but I also read that it only works with Windows. I'm using Mac systems and hoping for it to work with them.
Thanks,
Aaron
The extended indexing syntax is mentioned in python's doc.
slice([start], stop[, step])
Slice objects are also generated when extended indexing syntax is used. For example: a[start:stop:step] or a[start:stop, i]. See itertools.islice() for an alternate version that returns an iterator.
a[start:stop:step] works as described. But what about the second one? How is it used?
Dear All,
I would like to automatically generate a flowchart similar to this one ( http://en.wikipedia.org/wiki/File:%281%29_2008-04-07_Information_Management-_Help_Desk.jpg ) with Python.
Do you have any advice regarding the library I should use to draw boxes, arrows (with the shortest path), text and some colors.
Many thanks in advance !
I'm curious if their is some python magic I may not know to accomplish a bit of frivolity
given the line:
csvData.append(','.join([line.split(":").strip() for x in L]))
I'm attempting to split a line on :, trim whitespace around it, and join on ,
problem is, since the array is returned from line.split(":"), the
for x in L #<== L doesn't exist!
causes issues since I have no name for the array returned by line.split(":")
So I'm curious if there is a sexy piece of syntax I could use to accomplish this in one shot?
Cheers!
I want to be able to take a shortened or non-shortened URL and return its un-shortened form. How can I make a python program to do this?
Additional Clarification:
Case 1: shortened -- unshortened
Case 2: unshortened -- unshortened
e.g. bit.ly/silly in the input array should be google.com in the output array
e.g. google.com in the input array should be google.com in the output array
Thanks for the help!
I want to parse a html-page that unfortunately requires JavaScript to show any content. In order to do so I use a small python-script that pulls the html-code of the page, but after that I have to execute the JavaScript in a DOM-context which seems pretty hard.
To make it even harder I want to use it in a server environment that has no X11-server.
Note: I already read about http://code.google.com/p/pywebkitgtk/ but it seems to need a X-server.
In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example:
mydict = {'a': [3,5,6,43,3,6,3,],
'b': [87,65,3,45,7,8],
'c': [34,57,8,9,9,2],}
for k in mydict.iterkeys():
print k
gives me:
a
c
b
How can I do something similar in Javascript?
How can I log into my Launchpad account in a python script? Any sample code would be appreciated.
The login url is https://launchpad.net/+login and then redirect to something like https://login.launchpad.net/fJLVSRbxPfKTpVDr/+decide
Thanks in advance!
I have a script which reads data from a csv file. I need to store the data into a database which has already been created as
$ python manage.py syncdb
so, that automated data entry is possible in an easier manner, as available in the django shell.
Which technology is better to use in terms of performance for high performance scalable web application? PHP or Python?
The project is going to involve database.
Is there any short way to achieve what APT does in Python ?
I mean, when the package manager prompts a yes/no question followed by "[Yes/no]".
The scripts accepts YES/Y/yes/y or "enter" (defaults to Yes as hinted by the capital)
The only thing I find in the official doc is input/raw_input..
I know it's not that hard to emulate, but it's annoying to rewrite :|
What is the proper indentation for Python multiline strings within a function?
def method:
string = """line one
line two
line three"""
or
def method:
string = """line one
line two
line three"""
or something else?
It looks kind of weird to have the string hanging outside the function in the first example.
Thanks.

Well i'm learning Python cuz' i think is an awesome and powerful language like C++, perl or C# but is really really easy at same time. I'm using JetBrains' Pycharm and when i define a function it ask me to add a "Documentation String Stub" when i click yes it adds somethin like this:
"""
"""
so the full code of the function is something like this:
def otherFunction(h, w):
"""
"""
hello = h
world = w
full_word = h + ' ' + w
return full_word
I would like to know what these (""" """) symbols means, Thanks.
Ps.Data: Sorry for my bad english :D
