I don't know but If you can mess with tasklist and subprocess module (for XP/VISTA). This is purely untested as I'm not sure if tasklist returns anything!
Also what Data type of those variables? If they are numeric, then Just save them as strings. Then retrieve them and use int() or float() to convert them back o numerical values
If you didn't close the database connection.commit() db.close() you sould be able to access it via Database.db from the second program so try substituting that for self.database and see if it works, or just use self.database = Database.db
There you are! He is trying to call self.database which is'nt defined anywhere. This should at least work
Although this is off-topic: I have Python 2.6.3, I installed py2exe 0.6.9, and when I try to compile the program it gives some error, I can't post the error since I can't copy text from the command prompt. I did mention something about wx.core and some dll file (MSVCP90.dll). It works fine for other non-wxpython programs, but it doesn't work with this! How do I solve this?
Do you you code setup.py by yourself? If yes, Andrea Gavana have saved you alot of pain by making front end (GUI) for py2exe. It is called GUI2exe Get It here: http://code.google.com/p/gui2exe/ I use it with inno setup to make setups It is fantastic work!
If you still get errors, then open new thread. Oh by the way, Using wing IDE (101 version is free) will help you copy and paste errors. Any other decent IDE should be able to do that (even IDLE :))
Have you tried andrea gavana's gui2exe? It have many options that comes from py2exe. It have also other 'packers' options. Check if it can solve your problem
That's where sockets comes in MHO. You will use to send data to the server and then there will be a thread opened to server to save each query. So theoretically this is what I would do : 1. Connect to the server via sockets and server's mysql-python module 2. Use that connection to send queries 3. Close database connection and end socket session
try learning by dividing the issues at hand using functions: 1.Function that Gets numbers entered by the userand first ask the user how many numbers there are. 2. Find average should always be a float, even if the user inputs are all
#function to get numbers and store them --> store is only for practice
def getvalues():
how_many = raw_input("How Many Numbers are we operating on? \n")
#Chek if the provided answer is correct
try:
n = int(how_many)
return n
except:
print "You can't trick me, that is not integer!"
getvalues()
def storevalues(n):
s = []
for i in range(0, n):
ret = raw_input("Enter %dth number: \n" %(i+1, ))
s.append(ret)

cont+=float(i)
result = float(cont)/n_times
print "The result to two decimal places is %.2f" %(result, )

As jlm699 said, Postgresql is good but isn't the only one. You can go with mysql plus mysql-python. I have read yahoo! and many other big companies uses mysql(not sure if it is with Python or PHP) so I know it must be multiuser!
I was once a fond of global variables as "child" programmer. As I went on coding, things turned harsh on me. Thanks God I then learned OOP. In OOP, you do alot of stuffs without global variable. I have forgotten even last time i used global keyword. all I remember is alot of self.xyz and __init__
Alternatively you can use placeholder (same Snee's example)
#Convert C to F
def Tc_to_Tf ():
Tc = input ("What is the Celsius Temperature ? " )
Tf = 9.0/5.0 * Tc + 32
return Tf
Tf = Tc_to_Tf ()
#.2f instructs Python that placeholder holds float number with 2decimal places. try 3f, 4f etc and see how it does
print 'The temperature is %.2f Degrees Fahrenheit' %(Tf, )
if it was windows, I could use the system's taskkill with switches /f here is completely untested example. This will close any running instance of firefox :) Not sure about linux. I buried it long ago, though I plan to go back
import os
os.system("taskkill /F /IM firefox.exe")
The popular Geany IDE is written with GTK (not PyGTK).
Wing IDE is written in PyGTK
I would suggest wxPython, for easy learning curve (to my experience). Why? Because I grasped the basics even before I could be fluent in Python. I almost learned them simultaneously (though Python came first) :) PyQT? No, unless you will never develop any commercial app or you are willing to $. PyGTK? Yes why not? But if you want to!
a process is a program that runs with its own memory block and it own global variables. Processes don't share memory block, and cannot communicate directly except via inter process communication
Threads on other hand is "lightweight" process and share memory block and many other resources that processes don't share. To create a process you need new memory block, while thread share the parent thread's memory.
Single process can spawn many threads and as a matter of fact, a process is a single threaded or multithreaded. Hope haven't confused you too!
Hello, Why use WinDef while have McAfee? As far as I know, McAfee hav its own antispyware and there is no need to use multiple AS. So just disable one of them and I advice you disable WinDef
Another Advice, you can use system cleaners like ccleaner. It wipes out garbages in your disk. Check out here at www.ccleaner.com Bonus point is, it is freeware :)
Don't mess with hidden folders/files unless you know what you are doing! I don't know what they are, but take that advice seriously. May be use google :)
Why not? It worked for me when I tested his code... and there's nothing wrong with his binding as I added another menu item with a separate function and ID and that still worked without conflict.
here is what I got:
File "c:\Users\Elijah Ministries\Desktop\daniweb.py", line 17, in <module>
frame = MainFrame('Ya Mum')
File "c:\Users\Elijah Ministries\Desktop\daniweb.py", line 11, in __init__
self.Bind(wx.EVT_MENU, self.Close(), id=ID_FILE_QUIT)
File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\_core.py", line 3911, in Bind
event.Bind(self, id, id2, handler)
File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\_core.py", line 3985, in Bind
target.Connect(id1, id2, et, function)
File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\_core.py", line 3868, in Connect
return _core_.EvtHandler_Connect(*args, **kwargs)
Is sending a file Illegal? If not, then I can send It to you I have downloaded full via a link I provided above. I cannot test whether installation works or not as I use USB stick version and don't have Python (at work now). So If it is legal send me Email and I will send it to you :)
