Question or problem about Python programming:
Normally you can execute a Python script for example: python myscript.py, but if you are in the interactive mode, how is it possible to execute a Python script on the filesystem?
>>> exec(File) ???
It should be possible to execute the script more than one time.
How to solve the problem:
Use execfile(‘script.py’) but it only work on python 2.x, if you are using 3.0 try this
import file without the .py extension will do it, however
__name__ will not be
"__main__" so if the script does any checks to see if it’s being run interactively you’ll need to bypass them.
Alternately, if you’re wanting to have a look at the environment after the script runs try
python -i script.py
EDIT: To load it again
file = reload(file)
You might want to look into IPython, a more powerful interactive shell. It has various “magic” commands including
%run script.py (which, of course, runs the script and leaves any variables it defined for you to examine).
You can also use the
subprocess module. Something like:
>>> import subprocess >>> proc = subprocess.Popen(['./script.py']) >>> proc.communicate()
You can run any system command using python:
>>>from subprocess import Popen >>>Popen("python myscript.py", shell=True)
The easiest way to do it is to use the
import os os.system('python script.py')
os.system('cmd') to run shell commands. Hope it will be enough.
