[python] How can I make one python file run another?

How can I make one python file to run another?

For example I have two .py files. I want one file to be run, and then have it run the other .py file.

• you can run your .py file simply with this code:

import os 
os.system('python filename.py')

note: put the file in the same directory of your main python file.

It may be called abc.py from the main script as below:

#!/usr/bin/python
import abc

abc.py may be something like this:

print'abc'

I used subprocess.call it's almost same like subprocess.Popen

from subprocess import call
call(["python", "your_file.py"])

You'd treat one of the files as a python module and make the other one import it (just as you import standard python modules). The latter can then refer to objects (including classes and functions) defined in the imported module. The module can also run whatever initialization code it needs. See http://docs.python.org/tutorial/modules.html

Get one python file to run another, using python 2.7.3 and Ubuntu 12.10:

1. Put this in main.py:

   #!/usr/bin/python
   import yoursubfile
   

2. Put this in yoursubfile.py

   #!/usr/bin/python
   print("hello")
   

3. Run it:

   python main.py 
   

4. It prints:

   hello
   

Thus main.py runs yoursubfile.py

from subprocess import Popen

Popen('python filename.py')

You could use this script:

def run(runfile):
  with open(runfile,"r") as rnf:
    exec(rnf.read())

Syntax:

run("file.py")
