- Python Call A Program
Python 2.7 Tk filedialog calling external programs I'm beginning to learn how to use python and need to develop some applications for a lab project. ImportError: cannot import name getoutput (Biopython). For each library I've given a description and shown an example of calling an external command. Like' Python programs. You can call. On Windows, the. Running an outside program (executable) in Python? Ask Question 70. I bet that your external program, flow.exe, needs to be executed in its directory, because it accesses some external files stored there. Explorer will automatically open the file with whatever default windows program you have set for that file type. So no need to re. Control an external program using python. Programming Forum. I'm using Windows. Nonetheless, I found a way to control an external windows program! However, I would like to program a way for the program to tell python that it is done with its process and then for python to close the program. The only way I think of that working is.
Python Call A Program
P: n/a | What's the easiest and cleanest way of having PyQt bring up an external
application? In this case I am looking to launch Internet Explorer and
bring up a specific URL. I don't care about tracking the IE process'
activity and don't want PyQt to wait until the browser is closed. I
tried the following code from within a PyQt app:
import os
url = 'http://server.domain.com/page.html'
os.system('start %s' % url)
When I use this the PyQt app freezes up and only when I forcefully
close it does the browser window pop up. Then I looked into QThreads
and some other choices. Here's my latest attempt, using win32process:
import win32process
url='http://server.domain.com/page.html'
cmd_line = 'start %s' % url
win32process.CreateProcess(None, cmd_line, None, None,
1,win32process.CREATE_NEW_CONSOLE, None, None,
win32process.STARTUPINFO())
When I try this I get a message stating 'The system cannot find the
file specified' when the cmd_line is being interpreted. I am using
Python 2.3.5 on Windows 2000 Professional, with Qt 2.3.0 and PyQt 3.13.
Do I have to go to the lengths of implementing a QThread just to spawn
an external program I don't care about tracking?
