an easy one for all python artist [SOLVED]

I want to be able to call a command from my python script. my problem seem to big with exporting variable to this one.

e.g:           i got a variable that give me the name of name of the package to install.   (pacman, for example)

                  from subprocess import call
                  call(["pacman -S commando[package-1]"])
                                                -----------------------------------> my variable

Thanks.

You should have asked this in the "Programming & Scripting" sub-forum.

Pass your command as a list with multiple items or split it up. Example:

call(["pacman", "-S", "your_package"])

or

call("pacman -S your_package".split())

or

call("pacman -S your_package".split())

I think that the OP wants to pass a variable name as an argument instead of a string of the package name. In this case the following can be used:

var1 = "your_package"
call(["pacman", "-S", var1])

Edit: By the time I posted the thread was solved .

• Don't use shell=True, there is no sane reason to use it and it comes with some big downsides (like arbitary code execution)

• You probably want to check the return code to see if it actually worked or not.
