I am trying to run OpenScad through command prompt in windows 7. However I could not get it worked.
I added following directory to Path
"C:\Program Files\OpenSCAD\"
And tried to run the following script:
from os import listdir
from subprocess import call
files = listdir('.')
for f in files:
if f.find(".scad") >= 0: # get all .scad files in directory
of = f.replace('.scad', '.stl') # name of the outfile .stl
cmd = 'call (["openscad.com", "-o", "{}", "{}"])'.format(of, f) #create openscad command
exec(cmd)
Also I tried it with openscad, openscad.exe, openscad.com, no success so far.
The error I am getting is:
Traceback (most recent call last):
File "C:\Users\Desktop\scad2stl.py", line 9, in <module>
exec(cmd)
File "<string>", line 1, in <module>
File "C:\Users\AppData\Local\Programs\Python\Python35\lib\subprocess.py", line 247, in call

File "C:\Users\AppData\Local\Programs\Python\Python35\lib\subprocess.py", line 955, in _execute_child
startupinfo)
FileNotFoundError: [WinError 2] The specified file could not be found
Any suggestions?
I just saw this thread, I have make it work usign windows power shell, couldn't make it work on cmd due. So for example this doesn't work on cmd>
openscad -o render.png --imgsize=2048,2048 assembly.scad
but it does work on power shell (notice the ./ in the bigining):
./openscad -o render.png --imgsize=2048,2048 assembly.scad
hope it helps.
Best regards

I get a FileNotFoundError error while trying to call midi2audio.
I am working with Python 3.6 - Anaconda - Windows 10.
My .py file is in the same folder, together with the .sf2 and the .mid files.
My code is:
from midiutil.MidiFile import MIDIFile
from midi2audio import FluidSynth
soundfont = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\JR_sax.sf2'
filepath = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\input.mid'
fs = FluidSynth(sound_font=soundfont, sample_rate=22050)
fs.midi_to_audio(filepath, 'output.wav')
I would expect a .wav file in my folder being created.
I get instead:
runfile('C:/Users/matteo.stante/Documents/4_Python_Scripts/experiments/AudioBello.py', wdir='C:/Users/matteo.stante/Documents/4_Python_Scripts/experiments')

Windows: \\ (why 2? Because \ is used by formatting like \n \r ... so you need 2)
Linux: /
If the file is in the same folder, then
soundfont = 'R_sax.sf2'
filepath = 'input.mid'
EDIT
I tried it on my PC (windows 10) and I get same error. I documentation I didnt find any mention about OS, but there is obviously some linux commands.
Try this on Linux OS
EDIT2
I put little effort and tried it on Linux too.
1) Error the same - File not found
2) I found out you have to put folder somewhere on the path -command: $PATH
I put it to /usr/local/bin/fluidsynth
3) New error: Permission denied (couldnt pass it even with root)
4) I found that I dont have fluidsynth installed
command: apt install fluidsynth
5) your script worked (kind of, output.wav generated)
Possible solution
I believe that the problem - after installing fluidsynth on the linux - that your solution for Windows will be solved after installing fluidsynth on windows.

This is my code so far
from subprocess import call
call("/Users/oscar/Desktop/Controlled Assessment/Currency Converter.py")
When I run it I get this error message
Traceback (most recent call last):
File "/Users/oscar/Desktop/Controlled Assessment/ISBN Checker.py", line 10, in <module>

Since it looks like you're trying to execute another Python script, why not import it?
import Currency_Converter
And then run the modules you want in there? Take the space out of the file name and replace it with an underscore.
Check the interpreter directive from your script.
It should start with:
#!/usr/bin/env python
print 'your python script...'
That means that when you call this script directly, it will be interpreted by python binary.
You can get more info on http://en.wikipedia.org/wiki/Shebang_(Unix)
use subprocess.Popen
import sys, subprocess
subprocess.Popen([sys.executable, "myscript.py"])
This should run myscript.py within the Python command line.
So I have a python script that produces a networkx graph and exports it as .graphml and I want script to also be able to open cytoscape with the network loaded without any work on the users part. I understand:
cytoscape.bat -N C:\Somepath\with\a\networkx.graphml
and it works fine when I use it. As does:
cd "C:\Program Files\Cytoscape_v3.0.0"
cytoscape.bat
However, I can't seem to get either os.system or subprocess to run properly, my current configuration is:
p = subprocess.Popen("cytoscape.bat", cwd="C:/Program Files/Cytoscape_v3.0.0")
stdout, stderr = p.communicate()
But the throws a file-not-found-exception.
I've been reading up on other stackoverflow posts and python docs on running .bats and doing cmd operations, and can get the basics to work. However, this seems somewhat more complicated, and I'm not sure where I'm going wrong!
As requested I exceptions:
The file not found and incorrect path exceptions:

dll'.
Please install or use the JRE or JDK that contains these missing components.
C:\Program Files\Cytoscape_v3.0.0
From the documentation:
"If cwd is not None, the child’s current directory will be changed to cwd before it is executed. Note that this directory is not considered when searching the executable, so you can’t specify the program’s path relative to cwd."
You have to pass the full path of the command to subprocess.Popen.
i installed python-nmap-0.1.4.tar.gz in pyhton27 in window. When i ran this http://codepad.org/vTu1Uw7I script, i got a few error. What those error mean?. Are those error happened because i used python-nmap-0.1.4.tar.gz in windows?.
Here is the error

Seems that python-nmap is meant to be run on Linux… but you can still try to make it work on Windows. The problem is that it is trying to call nmap but the binary is not found in PATH.
Add the directory with nmap executable to you PATH variable. Here is a HOWTO.
I am trying to run an existing python code, and having issues with it.
This program required npm program installed and which is installed at C:\Program Files\nodejs\npm in my computer. When I run the following code, as a part of the whole program, it throws errors.
def popen_results(args):
proc = subprocess.Popen(args, stdout=subprocess.PIPE)
return proc.communicate()[0]
def installed():
"""docstring for npm_installed"""
return popen_results(["which", "npm"]).strip()

WindowsError: [Error 2] The system cannot find the file specified
I agree with martineau, it is unable to find which. The script may have been written with the assumption it was going to be run in a unix environment which would most likely have the "which" command available and in the default PATH. Since it looks like you're running this on Windows, I don't think it's going to work.
It looks like there is some alternatives to which on Windows though, discussed here: Is there an equivalent to which on Windows?
