如何从另一个python脚本调用python脚本？

Question

我有一个名为errorHandler.py的脚本和另一个名为test.py的脚本，它们都在同一个目录中。我在test.py中的try语句中故意输入了一个错误，我试图让errorHandler.py脚本抓住它。当它执行时，它不会失败或产生错误，但errorHandler.py脚本也不会启动。任何帮助，将不胜感激。下面是两个脚本...

#--errorHandler.py 

# python 3 
try: 
    from tkinter import *

    from tkinter import messagebox

根据lmgtfy

找一个Python文件运行另一个：

Put this in main.py: #!/usr/bin/python import yoursubfile. 
Put this in yoursubfile.py #!/usr/bin/python print "hello"; 
Run it: python main. py. 
It prints: hello.
