I am new to Heroku. I tried installing the library logging by specifying in the requirements.txt file and even using the web console, both times it returned with this error:

SyntaxError: invalid syntax
Any idea where am I going wrong or what I should do?
The logging module on PyPI is ancient, having been most recently updated in June, 2013. The specific error you're seeing is due to the old tuple syntax for except which was removed in Python 3.0.
You are probably just looking for the logging module that has been included with Python since version 2.3. Since it is part of the standard library you don't need to do anything to install it.
Remove it from your requirements.txt, commit, and redeploy.
