Not enough arguments for format string

[Kevin Walzer]

I'm getting an error in a Python script I'm writing: "not enough
arguments for format string." The error comes at the end of the
os.system command, referenced below. Any ideas?

---

import EasyDialogs
import os
import sys


password = EasyDialogs.Ask Password("To launch Ethereal, please enter
your password:")
binpath = os.path.join(os .path.dirname(s ys.argv[0]),
'/opt/local/bin/ethereal')

os.system('open -a X11.app; cd ~/; printenv; DISPLAY=:0.0; export
DISPLAY; echo %s | sudo -S %s; sudo -k' %password %binpath)

TypeError: not enough arguments for format string

Well, just try :
os.system('open -a X11.app; cd ~/; printenv; DISPLAY=:0.0; export
DISPLAY; echo %s | sudo -S %s; sudo -k' % (password, binpath) )

The reason is, you have 2 "%s" in yor string, thus after the "%"
operator, you need a 2-element tuple ! If you have either more or less
element, you'll get a TypeError ! In your code above you put a single
element ...

Missing a comma there :)

os.system('open -a X11.app; cd ~/; printenv; DISPLAY=:0.0; export
DISPLAY; echo %s | sudo -S %s; sudo -k' % (password, binpath))
