python shell运行快捷键是什么,Python脚本无法在键盘快捷键上运行

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("

")

f.write(HTMLresult)

f.write("")

# 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.
