Q:

creating a worksheet using gspread

I am new to python.  I was just trying to create a google worksheet using gspread.  I read about using google api's from here.  I downloaded credentials from Google Developers Console which is a file in json format.  Then I used this code
import gspread
from oauth2client.service_account import ServiceAccountCredentials
scope = ['https://spreadsheets.google.com/feeds']
credentials =     ServiceAccountCredentials.from_json_keyfile_name('spreadsheet1995.json', scope)
gc = gspread.authorize(credentials)
worksheet = gc.add_worksheet(title="A worksheet", rows="100", cols="20")

But it throws an error 'Client' object has no attribute 'add_worksheet' although I read documentation which included this attribute.  Here is the link which I followed.  Please help me sort out this problem. 

A:

First, you need to know to the difference between a spreadsheet and a worksheet.  A spreadsheet is a container of worksheets.  Like a book with many pages. 
If you go to Google Sheets and hit the big "+" button you will start a new a new spreadsheet.  This spreadsheet will at first contain a single worksheet named "Sheet1".  You may add more worksheets to your spreadsheet. 
Now back to gspread and your code sample. 
To create a worksheet you need a spreadsheet.  This is what you're missing in your code. 
Skipping the authentication part, you code should look like this:
gc = gspread.authorize(credentials)
spreadsheet = gc.open("The name of your spreadsheet")
worksheet = spreadsheet.add_worksheet(title="A worksheet", rows="100", cols="20")

Now with worksheet you may read cell values, edit them, etc.
