Is there a simple way to run a Python script on Windows/Linux/OS X?
On the latter two, subprocess.Popen('/the/script.py') works, but on Windows I get the following error:
Subprocess, 7-Zip. We can use external programs, like the 7-Zip compression software, to compress files. We invoke an external binary file. Here: We create a Windows command line that invokes the 7za.exe program. This is a backport of the subprocess standard library module from Python 3.2 - 3.5 for use on Python 2. It includes bugfixes and some new features. On POSIX systems it is guaranteed to be reliable when used in threaded applications. It includes timeout support from Python 3.3 and the run API from 3.5 but otherwise matches 3.2’s API. Oct 11, 2013 In the official python documentation we can read that subprocess should be used for accessing system commands. The subprocess module allows us to spawn processes, connect to their input/output/error pipes, and obtain their return codes. A program can create new processes using library functions such as those found in the os or subprocess modules such as os.fork, subprocess.Popen, etc. However, these processes, known as subprocesses, run as completely independent entities-each with their own private system state and main thread of execution. Python subprocess.call Function. In the previous section, we saw that os.system function works fine. But it’s not recommended way to execute shell commands. We will use Python subprocess module to execute system commands. We can run shell commands by using subprocess.call function. See the following code which is equivalent to the previous code.
monkut's comment: The use case isn't clear. Why use subprocess to run a python script? Is there something preventing you from importing the script and calling the necessary function?
Python offers several options to run external processes and interact with the operating system. However, the methods are different for Python 2 and 3. Python 2 has several methods in the os module, which are now deprecated and replaced by the subprocess module, which is the preferred option in.
I was writing a quick script to test the overall functionality of a Python-command-line tool (to test it on various platforms). Basically it had to create a bunch of files in a temp folder, run the script on this and check the files were renamed correctly.
I could have imported the script and called the function, but since it relies on sys.argv and uses sys.exit(), I would have needed to do something like.
Also, I wanted to capture the stdout and stderr for debugging incase something went wrong.
Of course a better way would be to write the script in more unit-testable way, but the script is basically 'done' and I'm doing a final batch of testing before doing a '1.0' release (after which I'm going to do a rewrite/restructure, which will be far tidier and more testable)
Basically, it was much easier to simply run the script as a process, after finding the sys.executable variable. Mustek 1200 ub driver. I would have written it as a shell-script, but that wouldn't have been cross-platform. The final script can be found here

Just found sys.executable - the full path to the current Python executable, which can be used to run the script (instead of relying on the shbang, which obviously doesn't work on Windows)
How about this:
This tells subprocess to use the OS shell to open your script, and works on anything that you can just run in cmd.exe.
Additionally, this will search the PATH for 'myscript.py' - which could be desirable.
Roman StarkovRoman StarkovYes subprocess.Popen(cmd, .., shell=True) works like a charm. On Windows the .py file extension is recognized, so Python is invoked to process it (on *NIX just the usual shebang). The path environment controls whether things are seen. So the first arg to Popen is just the name of the script.
It looks like windows tries to run the script using its own EXE framework rather than call it like
Try,
Edit: 'python' would need to be on your path.
viksitviksitYou are using a pathname separator which is platform dependent. Windows uses ' and Unix uses '/'.
For example, to execute following with command prompt or BATCH file we can use this:

Same thing to do with Python, we can do this:

YumYumYumYumYumYumWhen you are running a python script on windows in subprocess you should use python in front of the script name. Try:
