Python script won't run on keyboard shortcut
Question
So i have plenty of scripts which i run from keyboard shortcuts, things like uploading screenshots to imgur and putting links in the clipboard, stuff for digitising plots, etc.
I have this current script, which only runs from the terminal, and not when i try to run it as a keyboard shortcut.
I'm trying to run it via the System > Preferences > Keyboard Shortcuts on Scientific linux 6.4 .
I've included the script below, in case there's anything specific about it which would stop it from working.
#!/usr/bin/python
import fileinput, os
import subprocess
from pygments import highlight
from pygments.lexers import get_lexer_by_name, guess_lexer
import pygments.formatters as formatters
#stdin = "\n".join([line for line in fileinput.input()])
p = subprocess.Popen(["xclip", "-selection", "primary", "-o"], stdout=subprocess.PIPE)
code, err = p.communicate()
if not err:
lexer = guess_lexer(code)
print lexer.name
imageformatter = formatters.ImageFormatter(linenos=True, cssclass="source", font_name="Liberation Mono")
formatter = formatters.HtmlFormatter(linenos=True, cssclass="source")
HTMLresult = highlight(code, lexer, formatter)
Jpgresult = highlight(code, lexer, imageformatter, outfile=open("syntax.png", "w"))
with open("syntax.html", "w") as f:
f.write("<html><head><style media='screen' type='text/css'>")
f.write(formatters.HtmlFormatter().get_style_defs('.source'))
f.write("</style></head><body>")
f.write(HTMLresult)
f.write("</body></html>")
# os.system("pdflatex syntax.tex")
os.system("firefox syntax.html")
os.system("uploadImage.sh syntax.png")
else:
print err
The way it works, is by extracting the clipboard selection using xclip , using pygments on the text, and then both creating an html document and opening it in firefox, and uploading an image to imgur (using another script i have, which i know 100% works), and then putting that image url back into the clipboard.
The bin folder it resides in is in my path.
I've tried all of:
script
script.sh (where this file is just a shell script which calls the python script)
/home/will/bin/script
/home/will/bin/script.sh
as the command in the keyboard preferences .
If i change the contents of these scripts to just something like notify-send "hello" , and that then produces the notification message, so i'm fairlyconfident it's a probelm with the script, and not the keyboard shortcuts menu.

I ran into exactly the same issue. Here's how I fixed it:
First of all, I wrote a one-liner shell script that looked something like python /home/user/Scripts/script.py where "/home/user/Scripts/script.py" was the location of my Python. I placed this shell script in the executable path.
Next, when I went to make my shortcut, I didn't tell the computer to run the file. I told the computer to start a terminal and gave the shell script as an argument to that terminal. In my case, it looked something like: xfce4-terminal -x ralia.sh .
This works for me.

A possible issue is $PATH being different between your interactive shell and the environment of the daemon or program that handles keyboard shortcuts.
Try right after "import os":
open("/tmp/debug.txt", "w").write(os.environ["PATH"])
Then run it with the keyboard shortcut and look at /tmp/debug.txt .
→ Try absolute paths for the binaries and if that doesn't help, consider jhutar's advice.

The problem is in "with open("syntax.html", "w") as f:". When using keyboard shortcuts for the script, use full path of the files in the script.
Instead of:
with open("syntax.html", "w") as f:
Use:
with open("/home/user/my_script_folder/syntax.html", "w") as f:
Change all filenames in your script to full path and it should work.

I have had a similar issue. The problem is that it is necessary to use full paths to make it work using keyboard shortcuts.
In my case, this did not work:
#!/bin/bash
python scrypt.py
However, this did work:
#!/bin/bash
python /home/user/bin/scrypt.py
