I have 2 .py files: test.py and test2.py
test.py:
import test2
print("This is test.py")
test2.py:
print("This is test2.py")
When I run test.py, I get:
This is test.py
How can I print "This is test2.py" by running test2.py from test.py?
Solution found:
test.py:
print("This is test.py")
exec(open("test2.py").read())
test2.py:
if __name__ == '__main__':
print("This is test2.py")
Output:
This is test.py
This is test2.py
exec(open("main2.py").read())

exec is a serious security risk, and in general running subprocesses is not encouraged and has lots of considerations (e.g. what do to, and how to monitor child process end, how to handle or even receive the errors, what happens when main process crash - you get leaky process etc.)I think that there are many ways to do, but I think that subproccess will help you:
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. Here is the documentation: https://docs.python.org/3/library/subprocess.html
importdoes exactly what you want.
