Connecting with Google Spreadhseet using python 3 - python-3.x

Question

I am using the following code to connect to the google spreadsheet.
import gspread
from oauth2client.service_account import ServiceAccountCredentials
scope = ['https://spreadsheets.google.com/feeds',
'https://www.googleapis.com/auth/drive']
credentials = ServiceAccountCredentials.from_json_keyfile_name("credentials.json", scope)
gc = gspread.authorize(credentials)
and I have the credentials.json which I exported from the Google Sheets API console.
But I am getting the following error:
TypeError: cannot use a string pattern on a bytes-like object
This is the complete trace of error:
