Question

I’ve written two python scripts script1.py and script2.py. I want to run script1.py from script2.py and get the content of the variables of script1 created during the execution of script1. Script1 has several functions in which the variables are created including in the main.

Thank you for all your answers. I’ve examined your answers and it doesn’t seem to work.
Here are the guilty scripts I’m talking about :

script1.py

def main(argv):
    """Main of script 1
    Due to the  internal structure of the script this 
    main function must always be called with the flag -d
    and a corresponding argument.
    """
    global now
    now = datetime.datetime.now()

    global vroot_directory
    vroot_directory = commands.getoutput("pwd")

    global testcase_list_file
    testcase_list_file = 'no_argument'

    try:
        opts, args = getopt.getopt(argv, "d:t:", 
            ["directory_path=", "testcase_list="])
    except getopt.GetoptError, err:
        print command_syntax
        sys.exit()
    for opt, arg in opts:
        if opt in ("-d", "--directory"):
            vroot_directory = arg
        if opt in ("-t", "--testcase"):
             testcase_list_file = arg

    def function1():
        pass  

    def function2():
        if testcase_list_file == 'no_argument':
            function1()
        else:
            function2()

if __name__ == "__main__":
    main(sys.argv[1:]) 

---

script2.py

from Tkinter import *

class Application:
    def __init__(self):
        """ main window constructor """
        self.root = Tk()
        # I'd like to import here the variables of script1.py
        self.root.title(script1.vroot_directory)   ?
        self.root.mainloop()

# Main program
f = Application()

Sorry for my mistakes and thank you for your pertinent remarks. I’ve got the following error message :

” AttributeError: ‘module’ object has no attribute ‘vroot_directory’ “

To be more specific I’d like to have something similar to the following :

from Tkinter import *
import script1

class Application:
    def __init__(self):
        """ main window constructor """
        self.root = Tk()
        script1.main(-d directory -t testcase_list_file) # to launch script1
        self.root.title(script1.vroot_directory)   # and after use its variables and functions
        self.root.mainloop()

# Main program
f = Application()

I think what you are looking for is some form of object persistence. I personally use the shelve module for this:

Script 1:

import shelve

def main(argv):
    """Main of script 1
    Due to the  internal structure of the script this 
    main function must always be called with the flag -d
    and a corresponding argument.
    """

    settings = shelve.open('mySettings')

    global now
    now = datetime.datetime.now()

    settings['vroot_directory'] = commands.getoutput("pwd")

    settings['testcase_list_file'] = 'no_argument'

    try:
        opts, args = getopt.getopt(argv, "d:t:", 
            ["directory_path=", "testcase_list="])
    except getopt.GetoptError, err:
        print command_syntax
        sys.exit()
    for opt, arg in opts:
        if opt in ("-d", "--directory"):
            settings['vroot_directory'] = arg
        if opt in ("-t", "--testcase"):
            settings['testcase_list_file'] = arg

    def function1():
        pass  

    def function2():
        if testcase_list_file == 'no_argument':
            function1()
        else:
            function2()

if __name__ == "__main__":
    main(sys.argv[1:]) 

Script 2:

from Tkinter import *
import shelve

class Application:
    def __init__(self):
        settings = shelve.open('mySettings')

        """ main window constructor """
        self.root = Tk()
        # I'd like to import here the variables of script1.py
        self.root.title(settings['vroot_directory'])   ?
        self.root.mainloop()

# Main program
f = Application()

The shelve module uses the pickle module in its implementation, so you could also look at pickle module for another approach.
