I'm writing a simple alarm utility in Python.
#!/usr/bin/python
import time
import subprocess
import sys
alarm1 = int(raw_input("How many minutes (alarm1)? "))
while (1):
time.sleep(60*alarm1)
print "Alarm1"
sys.stdout.flush();
doit = raw_input("Continue (Y/N)?[Y]: ")
print "Input",doit
if doit == 'N' or doit=='n':
print "Exiting....."
break
I want to flush or discard all the key strokes that were entered while the script was sleeping and only accept the key strokes after the raw_input() is executed.
Hi,
Is there a way to declare a constant in Python. In java I will we can create constant in this manner:
public static final String CONST_NAME = "Name";
What is the equivalent of the above java constant declaration in python ?
Cheers,
I have a messages folder(package) with __init__.py file and another module messages_en.py inside it. In __init__.py if I import messages_en it works, but __import__ fails with "ImportError: No module named messages_en"
import messages_en # it works
messages = __import__('messages_en') # it doesn't ?
I used to think 'import x' is just another way of saying __import__('x')
Hi everyone,
I have the following input:
input = [(dog, dog, cat, mouse), (cat, ruby, python, mouse)]
and trying to have the following output:
outputlist = [[0, 0, 1, 2], [1, 3, 4, 2]]
outputmapping = {0:dog, 1:cat, 2:mouse, 3:ruby, 4:python, 5:mouse}
Any tips on how to handle given with scalability in mind (var input can get really large).
I have Python classes, of which I need only one instance at runtime, so it would be sufficient to have the attributes only once per class and not per instance. If there would be more than one instance (what won't happen), all instance should have the same configuration. I wonder which of the following options would be better or more "idiomatic" Python.
Class variables:
MyController(Controller):
path = "something/"
childs = [AController, BController]
def action(request):
pass
Instance ariables:
MyController(Controller):
def __init__(self):
self.path = "something/"
self.childs = [AController, BController]
def action(self, request):
pass
How would you prompt the user for some input but timing out after N seconds?
Google is pointing to a mail thread about it at http://mail.python.org/pipermail/python-list/2006-January/533215.html but it seems not to work. The statement in which the timeout happens, no matter whether it is a sys.input.readline or timer.sleep(), I always get:
<type 'exceptions.TypeError'>: [raw_]input expected at most 1 arguments, got 2
which somehow the except fails to catch.
I am using python and want to create a fullscreen window. I know about the pygame.FULLSCREEN flag but when I use that there's areas of black around the screen. Is there any way to get the monitor size using python so I can make the window the correct size?
Hi,
I want to tokenize a given mathematical expression into a binary tree like this:
((3 + 4 - 1) * 5 + 6 * -7) / 2
'/'
/ \
+ 2
/ \
* *
/ \ / \
- 5 6 -7
/ \
+ 1
/ \
3 4
Is there any pure Python way to do this? Like passing as a string to Python and then get back as a tree like mentioned above.
Thanks.
Hi Everyone,

Hi,
I am writting a python script and I am running out of time. I need to so some things that I know pretty well in bash, so I just wonder how can I embed some bash lines into a python script.
Thanks
I'm trying to import a module, while passing some global variables, but it does not seem to work:
File test_1:
test_2 = __import__("test_2", {"testvar": 1})
File test_2:
print testvar
This seems like it should work, and print a 1, but I get the following error when I run test_1:
Traceback (most recent call last):
File ".../test_1.py", line 1, in <module>
print testvar
NameError: name 'testvar' is not defined
What am I doing wrong?

I have a bunch of HTML files I downloaded using HTTPLIB2 package in Python. ' ' are showing as 'Â '.
02/12/2004Â is showing while 02/12/2004 is the desired format.
How do I replace the 'Â ' with ' ' in Python? Thanks a lot!
I've just downloaded OpenCV's trunk and now I'm trying to build it with MinGW. I read the manual and get .dll's compiled, but that's all - "interfaces/python" contains only some .i and .cmake files. How can I really get new python interface? Where I can find new cv.pyd/libcv.dll.a (because a compiled version from official site crashes sometimes and I saw this bug as "fixed" in Trac)?
I have a directory structure:
example.py
templates/
__init__.py
a.py
b.py
a.py and b.py have only one class, named the same as the file (because they are cheetah templates). For purely style reasons, I want to be able to import and use these classes in example.py like so:
import templates
t = templates.a()
Right now I do that by having this in the template folder's __init__.py:
__all__ = ["a", "b"]
from . import *
However, this seems pretty poor (and maybe superfluous), and doesn't even do what I want, as I have to use the classes like this:
t = templates.a.a()
Thoughts?
I need to create a large matrix (array) structure (3 axis) and each element should store the reference to a Python object (myclass instance). Is it possible to use numpy to create such an array. Which data type should I use in order to store Python references?
The advantage of numpy is the support of slicing at different levels. The alternativee is to create a nested (nested) list but it is a cumbersome solution.
Hi All,
I know that there is the PyObjC bridge is OSX and what I want to do is to put a python application/script in the rightclick context menu of OS X. there is the OnMyCommand plugin but I dont think that supports python. I've had a look at how to do it in Carbon/ Objective-C and i'll admit it im a wuss and am just not smart enough yet to grok how to do it (I aint even close to groking it actually.)
Anybody got any idea's on how I might go about this?
Cheers
When I try to print a Unicode string in a windows console, I get a "UnicodeEncodeError: 'charmap' codec can't encode character ...." error. I assume this is because the Windows console does not accept Unicode-only characters. What's the best way around this? Is there any way I can make Python automatically print a "?" instead of failing in this situation?
Edit: I'm using Python 2.5.
In Python, is there a mean to enforce the use of spaces or tabs indentation with a per file basis ?
Well, perhaps "enforce" is too strong, its more like "recommands".
I keep getting files with mixed indentation and this is annoying... (to say the least) Python itself can tell when there is a problem, but I am searching something to do that at the editor level, like it exists for the charset.
Is there any python library that can keep a client-side SQLite database in sync with a server-side PostgreSQL database?
There are solutions for Java, such as Daffodil or SymmetricDS. Is there something similar for python?
Hi guys, I had written a program in Python 3, but now want to convert it into Python 2 code. Are there any utilities to do that automatically?
Thanks, R
Hello. I have a Java app that takes pretty much time to be initialized (so I can't use command-line like interface) and I need to pass text and receive the output of a Java method from Python. Is it possible to load the Java application, have it opened all the time the Python script runs and use a method from that app?
I'm writing python package/module and would like the logging messages mention what module/class/function they come from. I.e. if I run this code:
import mymodule.utils.worker as worker
w = worker.Worker()
w.run()
I'd like to logging messages looks like this:
2010-06-07 15:15:29 INFO mymodule.utils.worker.Worker.run <pid/threadid>: Hello from worker
How can I accomplish this?
Thanks.
