Call a Python script from another Python script with list as argument?

Question

I am trying to run a Python script a.py from another Python script scheduler.py and I want to pass a list as argument something like:

Scheduler.py:

t = {"code": 161123134, "name": "task2", "domain": "www.google.com", "type": "Type1", "keywords": ["bai2", "yin4", "jiao3", "yi8", "ping1", "tai3"]}

hourTasks = json.dumps(t)
os.system("python a.py " + hourTasks)

a.py

task = sys.argv[1:]
task = json.loads(task)

However It gives me an error the JSON object must be str, bytes or bytearray, not 'list'. Anyone know what the problem is?

It might be easier to do a bit of rewriting to a.py, and use it as a module instead. Otherwise, consider using the subprocess module instead of os.system(). — user707650

The error is unrelated to running a Python script from another script. task in json.loads(task) is a list, not a string. — user707650

You want sys.argv[1] (the first argument), not sys.argv[1:] (a list containing the first, and any other, arguments). — chepner

Try this:

Scheduler.py:

import json
import subprocess

t = {"code": 161123134, "name": "task2", "domain": "www.google.com", "type": "Type1", "keywords": ["bai2", "yin4", "jiao3", "yi8", "ping1", "tai3"]}

task = json.dumps(t)
subprocess.call(["python", "a.py", task])

a.py:

import json
import sys                                                                                        

task = sys.argv[1]
t = json.loads(task)

from one script you should import the other and there is no need to use json between your two scripts, just pass an python dict instead.

You could use the method of the dicts, to read the keys and the values. And before that do a counter and membership check like. For x in xs:
