print("This is test.py")

test2.py:测试2.py：

print("This is test2.py")

When I run test.py, I get:当我运行 test.py 时，我得到：

Answer 2

I think that there are many ways to do, but I think that subproccess will help you:我认为有很多方法可以做，但我认为 subprocess 会帮助你：

subprocess.run(["python", "path/to/test2.py"])

This will execute a shell command to open python and then tell him(python) to open and execute test2.py.这将执行一个 shell 命令打开 python 然后告诉他（python）打开并执行 test2.py。 Here is the documentation: https://docs.python.org/3/library/subprocess.html这是文档： https://docs.python.org/3/library/subprocess.html
