Answer 1

In this solution to your problem is putting your input in brackets (,) so the result would look something like this:

user_input = (raw_input("Enter year:"), )

Don't forget to put the comma,

In full you have

import MySQLdb
servername = "localhost";
username = "username";
password = "password";
conn = MySQLdb.connect(user=username,host=servername, passwd=password, db=db)
cursor = conn.cursor()
user_input = (raw_input("Enter year:"), )
query= ("SELECT * from country IndepYear")
cursor.execute(query,user_input)
