I don't think this does answer the question as subprocess.Popen(sys.argv[2:]) would be used to run a command not a Python function call. The emphasis on response suggests that it is not just about the function returning a value, but a valid flask.Response object which can print a message, return a status code etc. How to call ProTip: shlex.split can help you to parse the command for run, call, and other subprocess functions in case you don't want (or you can't!) python Note: To call an inner function, we must first call the outer function. provide_automatic_options controls whether the OPTIONS method should be added automatically. provide them in form of lists: import shlex import subprocess subprocess.run(shlex.split('ls -l')) call Python - Flask Login Form Example Call other functions from main().

Remember that the Python interpreter executes all the code in a module when it imports the module. ; Add the below code into the app.py A module can be written in C and loaded dynamically at run-time, like the re (regular expression) module. However, wrapper() has a reference to the original say_whee() as func, and calls that function between the two calls to print(). Python Python Modules and Packages Python Modules: Overview.
