You can use this module https://pypi.python.org/pypi/pyserial but as I understand it reading the post if a blocking operation and it may not be threadsafe. You should not call it from the web app itself. You should created a separate service that reads the serial post and writes the results in a file. Then the web app reads the data from the file. Of you can use some other communication protocol between the serial code and the web app.
