Run a python script from another python script, passing in args
Suppose I have script2.py that returns a int value.
Is it possible to run only script.py on my shell and within script.py gets in some way the int value returned by script2.py according to parameters I passed to script.py?
Yes it's possible. That's what modules are used for :).
First you have to put the method that you use in script2.py into a function. I'll use the same example as the person above me has used (because it's a good example :p).
def myFunction(a, b):
return a + b
Now on your script.py, you'll want to put:
import script2
at the top. This will only work if both files are in the same directory.
To use the function, you would type:
# Adding up two numbers
script2.myFunction(1, 2)
and that should return 3.
Could execfile be what you're after? execfile('script2.py') will work as if you had copied and pasted the entire contents of script2.py into the console.
e.g. suppose script2.py has:
def myFunction(a, b):
return a + b
and then in script.py I could do:
# reads in the function myFunction from script2.py
execfile('script2.py')
myFunction(1, 2)
If you want to execute script2.py with parameters passed in from script.py then I suggest that the contents of script2.py are encased in a function. That is, if your script2.py is:
a = 1
b = 2
result = a + b
I'd suggest you convert it into:
def myFunction(a, b):
return a + b
so that you can specify a and b from script.py.
Try this:
import subprocess
x = 55
print "running bar.py..."
subprocess.call("python bar.py " + x)
