This is the python code I was trying to access the cell information
from a google spreadsheet but the issue is that i am able to make it
work on Eclipse but when i deploy it, it is not showing me the result.
Maybe I am missing some of the google packages to import that is
making it unable to run on google environment. Kindly guide me.Thanks
in advance.
