MySQL or Google sheet as data source for Autocomplete

Using Google sheet as data source

import pygsheets
path='G:\\My drive\\testing\\google-sheet\\creds1.json'
gc = pygsheets.authorize(service_account_file=path)
sh = gc.open('my_gsheets1') # Open the google sheet 
wk1 = sh[0] # work sheet 1
my_list=wk1.get_col(2,include_tailing_empty=False)

Using MySQL database table

from sqlalchemy import create_engine
my_conn = create_engine("mysql+mysqldb://id:password@localhost/my_tutorial")
q="SELECT name FROM student "
my_cursor=my_conn.execute(q)
result=my_cursor.fetchall()
print(result)
my_list=[r for r, in result]

Using SQLite database

#my_conn = my_conn = create_engine("mysql+mysqldb://id:password@localhost/my_tutorial")
my_conn = create_engine("sqlite:///G:\\My Drive\\testing\\my_db\\my_db.db")
