如何使用一个 Python 脚本运行另一个 Python 脚本并将变量传递给它？

Question

I have one Python script. Let's call it controller.py . I'd like to use controller.py to run another Python script and pass several variables to it. Let's call the second script analyzer.py .

What is the best way to do this without importing analyzer.py as module? And how do I reference the variables I'm passing to analyzer.py within that script?

Here's my failed attempt using subprocess:

controller.py

import subprocess

var1='mytxt'
var2=100
var3=True
var4=[['x','y','z'],['x','c','d']]
var5=r"C:\\Users\\me\\file.txt"

myargs=var1,var2,var3,var4,var5
my_lst_str = ' '.join(map(str, myargs))
my_lst_str ='python analyzer.py '+my_lst_str

subprocess.call(my_lst_str,shell=True)

analyzer.py

print 'Argument List:', str(sys.argv)

I have looked through similar questions on Stack Overflow. One oft-recommended solution I tried was importing analyzer.py as a module, but analyzer.py defines many different functions. Using it as a module creates lots of nested functions, and managing the scope of variables within those nested functions was cumbersome.

I need to use Python 2 for these scripts. I'm on a Windows 10 machine.

Answer 1

1- exec command:

python2:

execfile('test.py')

python3:

exec(open('test.py').read())

2- os command:

test1.py:

import os 

#os.system('python test2.py')
os.system("python test2.py arg1 arg2")  

test2.py:

import sys

print 'Number of arguments:', len(sys.argv), 'arguments.'
print 'Argument List:', str(sys.argv)

3- subprocess command:

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

for passing argument and shell command use subprocess (plz see this Link ):

import subprocess

# Simple command
subprocess.call(['ls', '-1'], shell=True)

another example code:

file1.py:

args ='python file2.py id ' + 1
subprocess.call(args)

file2.py:

import sys

print 'Number of arguments:', len(sys.argv), 'arguments.'
print 'Argument List:', str(sys.argv)

4- socket pogramming : share data between two or many python file you can use socket programming : see this Link .
