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.
Use execfile('script.py') but it only work on python 2.x, if you are using 3.0 try exec(open('script.py').read())
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)
Alternately, if you're wanting to have a look at the environment after the script runs try python -i script.py This is epic thank you!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 os module:
import os
os.system('python script.py')
In fact os.system('cmd') to run shell commands. Hope it will be enough.
myscript.pyhave a proper "main" function? Why can't youimport myscriptandmyscript.main()? That's the usual approach. Why won't that work? Can you fix myscript to add a proper "main" function?PYTHONSTARTUP=some_script.py python -i. This will execute some_script.py and drop you to an interactive shell. If your working script defines local variables, you'll be able to access them from the shell. This can be really handy when trying to experiment with code or analyze behavior after the fact.
