How To Send Python Variable To Bash Variable?

I am trying to use Python to select a variable from a list, then speak it outloud using the bash command. Right now I have something like this foo = ['a','b','c','d'] from random i

Solution 1:

I suppose you can use os.system, but better might be subprocess:

import subprocess
subprocess.call(['say',x])

Solution 2:

you are passing astring you can use value of x like

sytem('say {0}'.format(x))

When passing strings you can use string formatting. As you realized you need to get the value of x in the string not the variable x http://docs.python.org/library/string.html#format-examples

Solution 3:

You can use format:

system('say {}'.format(x))

Solution 4:

use string formatting:

In [9]: x="ls -ld"

In [10]: os.system("{0}".format(x))
