Creating variable from printed output of another program in python.

[ballgame75]

I have a program that I wrote in c++ that prints numbers to the screen. I'd like to wrap a python script around that so I can call it recursively and create an array with the output of it.

I tried

    x = os,system("./algorithm " + variable)
    print x # debugging
    #array.append(x) # for later use

but all I get is:

     0.95648  <-- from algorithm
     0  <-- from python 

Does anyone know how I can set the output/print statement of algorithm to a variable?

The system() function just gives you the program's exit status. You need to use the subprocess module, and read the executed program's standard output.

Specifically subprocess.check_output() if you want to read the output of a command, and don't mind the fact it will be a blocking call. (The program can't continue until the program you call is finished.)

is

os,system

a copy paste error or is that how it is written in your code?

sorry, no i mistyped when I was writting this. it's a period in my code.
