google spreadsheet CellNotFound Exception using python issue - google-apps-script

Question

I am building Discord bot which ask user for their name and Points. My spreadsheet has two columns with first raw as header (Name, Points). my code take the name of the player and search the spreadsheet if found update the point. This works perfect when the player name already found but i get cellnotfound error when the name is not in the google sheet.
i have already tried solution in other forum but non are working like
if len(cells) > 0 and except gspread.exceptions.CellNotFound: and except gspread.CellNotFound:
import gspread
from oauth2client.service_account import ServiceAccountCredentials
from pprint import pprint
from googleapiclient import discovery
# SET UP GSHEETS DESTINATION
scope =["https://spreadsheets.google.com/feeds",'https://www.googleapis.com/auth/spreadsheets',"https://www.googleapis.com/auth/drive.file","https://www.googleapis.com/auth/drive"]
creds = ServiceAccountCredentials.from_json_keyfile_name("generated.json", scope)
client1 = gspread.authorize(creds)
content = "22"
if content.isdigit():
#open spreadsheet
sh = client1.open("test")
worksheet = sh.sheet1
nameof= 'player4'
#find data with playername
cells = worksheet.find(nameof)
if cells != []:
#capture player name data column and row number
#print("found at R%s C%s" %(cells.row, cells.col))
name_row_number = ("%s"%(cells.row))
name_cell_number = ("%s"%(cells.col))
old_points_cell_number = int(name_cell_number)+1
#print(old_points_cell_number)
oldscore = worksheet.cell(name_row_number, old_points_cell_number).value
#print(oldscore)
worksheet.update_cell(name_row_number, old_points_cell_number, content)
else:
print("name not found")
