Question

我一直在努力运行python mainmodel.py模型（模型使用“mainmodel.py”模型，从命令的所有内容开始）。

问题是我无法在python循环中运行此模型。在模型的敏感性分析中，ideia在不同条件之间运行模型（15个参数中的每一个都有许多变化）。我很想用这个： How to run a Python script from another Python script in the cross-platform way?

或

How to run a python script from another python script and get the returned status code?

我调用“mainmodel.py”的代码很简单，只有在运行模型时，我的代码才能调用“mainmodel.py”：

import mainmodel
import subprocess
import sys

for t in range(3):
    print 'MAJOR LOOP %s T'%t
    for i in range(2):
        subprocess.call((sys.executable, "mainmodel.py"))
        print 'MINOR LOOP %s'%i

问题是，我们需要测试模型中的许多参数。因为这样做（在analisys的敏感性）自动化!! 提前致谢！！ Isaque

        #Please check the below code. Hope it helps.

        #Demo for mainmodel.py
        import sys

        def check_args(temp1,temp2):
            if temp1 == temp2:
                return True
            else:
                return False

        def main():
            arg1 = sys.argv[1]
            arg2 = sys.argv[2]
            print "I am in mainmodel.py"
            ret = check_args(arg1,arg2)
            if ret:
                #print "Success"
                sys.exit(0)
            else:
                #print "Fail"
                sys.exit(1)

        if __name__ == '__main__':
            main()
    #=========================================================

    #Calling mainmodel.py with args testing 

    import os
    for t in range(3):
        print 'MAJOR LOOP %s T'%t
        for i in range(3):
            print 'MINOR LOOP %s'%i
            cmd =  "python mainmodel.py "+ str(t) +" " + str(i) 
            print cmd
            ret_main_model = os.system(cmd)
            if ret_main_model == 0:
                print "Success"
            else:
                print "Fail"
            print "-----------------------------"

另一种方法是触发__main__哨兵。有关详细信息，请查看：
