I have written a simple software for creating passwords. But when converted to exe and run file, the terminal screen closes after about 1 second.I have also installed all the modules. The software is available at the link below.Please help me.

The reason it is closing is because your application completed. You either need to have a dialog box which allows the user to click close, or at a minimum a sleep before you call exit(). This is the same for a .bat script in which the behavior you describe is a terminal window flickering for a second and going away.
I have a Raspberry Pi running Linux. My plan is that I can plug in a USB in the robot and have and it will run the python files. the reason I chose this method is that it allows for easy editing and debugging of the scripts.
Is there a way to execute my files when the USB is inserted?
Try to use os.path.exists to detect whether the pendrive is there in an infinite loop and when detected execute code on pendrive using os.system and break out of loop .

Looks like you should consider writing a script that navigates to the directory of the file and runs "python yourscript.py". The details on getting the script to autorun are there.
This question already has answers here:
How do I run a Python program in the Command Prompt in Windows 7?
(24 answers)
Closed 7 years ago.
So I'm an extreme beginner to programming, just starting the Python class on Coursera. Using Python 2.7.10
Anyway, I made a simple print statement script in Notepad++
print "Hello World"
and saved as a python file on my desktop
newprog.py
However when I try to run it a cmd window appears and disappears and I'm not quite sure whats wrong.
The other question that this was linked as a duplicate to is about accessing python through the command prompt, which I don't have a problem with. From answers given it is now apparent to me that my dilemma was due to an erroneous belief that the interpreter would remain open after running whatever script I wrote.
Sounds like your program simply opened, ran and exited. So nothing was wrong, it just all happened a bit quick for you to see it.
You should run it from a command prompt or get an IDE like Pycharm, which will allow you to both write and run your script in one program.
To run from command prompt, use either Windows Key + R and type 'cmd' or click start and type 'cmd' into search box. Then you can drag your script to the command prompt window and press Enter to run it.
If you wanted to run it by double click, you'd need something to stop it from finishing until you'd read the message. To achieve this you can use the raw_input function, which waits for user input.
So your script would then look like
print "Hello World"
raw_input("Press Enter to exit")
Then you could double click and press enter when you are ready to exit.
Go to the command prompt window
python
then type in
execfile('path to newfile.py here')
Your file will now be executed
I'm running python 3.4.3. But it should be the same, I hope.
Go go "..\PythonXX\Lib\idlelib" and look for idle.pyw NOT idle.py and using the you're able to execute simple one line commands like the one you have up there.
From that you can also create a new file and do more complicated stuff.
If you create a shortcut to your desktop, you'll be able to access it easier.
Let me know if it helps, or at least correct path.
Your script is probably working and then finishing, the result is shown but not for long. I recommend opening the console and running your script from there, or you could use a simple batch file to run python scripts and then wait for a key press.
To open the console you can use the Windows key along the R key, Win-R (to run a new process) and write cmd, or you look for cmd in your Window's start menu.
With the console opened, you must locate the path where your script is, you can use the cd (Change Directory) to get there, for example:
cd C:\Users\your_name\Desktop
and then write:
python newprog.py
to run your script.
Another option is to use this simple batch file (save it as python34.bat or similar, but the extension must be .bat, put it wherever you like):
#ECHO OFF
C:\Python34\python.exe %*
pause
#ECHO ON
And then use that to run your scripts by right clicking a python script file, open with (run with) and use this batch script as default (if you want). Also, if you have another version of Python, or is installed elsewhere, you must change the "C:\Python34\" part.
This is a computer we're talking about here. It might take you triple the time it takes a computer to multiple two numbers for example. With this notion in mind, the computer quickly prints then exits.
raw_input() # at the end of script wait for user to supply input, delaying script exit
i want to make a application with pyinstaller that run on mac and windows os...
if it was something like check my(s) online site(s) and see if it's on, i want it to auto-run always i start my pc and on background while is on and i'm using it
if it goes down a alarm sound start and pop up a window (starting the gui app where you do stuff like add your sites, set alarm and etc...) saying the link and info, the whole concept isn't (personal use + upload opensource),
My problem is, how i make it run on boot after the installation without needing to do anything else,
in one line:
how i startup a program on boot(enable it through installation), in windows/mac os?
I have a weird issue on a friends machine where when they run my script, it only flashes the command window when it hits a line that does something with os.system. It seems to not show the command window at all otherwise. Not showing is fine, but my script does a large process and it causes the window to flash a lot.
Normally on my machine, when I open the script (that launches a gui with tkinter) the command window will open as well in the back. This is what I am trying to get my friends to do, but I do not know what would cause the command window to not show. Is there a setting within python somewhere that doesn't show the command window (unless of course it needs to run a process in it)?
Edit: Ok I did a really lame hack to fix this. Apparently all he .py files got associated with pythonw. I was unable to get this association changed (even going through the command prompt ASSOC) So I just did a silly renamed of the pythonw to old_pythonw, and renamed the python.exe to pythonw.exe. Yes, really silly but no time to argue with windows about file associations.
