        cursor=db.cursor()
        #cursor.execute("drop table if exists")
        cursor.execute('''create table if not exists ACCOUNT (
              Account_ID int PRIMARY KEY,
              Account_Name varchar(250),
              Account_Size int,
              Account_Duration int,

        for i in range(n):
            Id=int(input())
            name=input()
            size=int(input())
            duration=int(input())
            budget=float(input())
            status=input()
            cursor=db.cursor()

            #cursor.close()
            
account=accountManage()
choice=int(input("enter choice....1:connection, 2.create table 3. insert no of rows"))
if(choice==1):
    account.connection()
elif(choice==2):

CodePudding user response：

You are using '?' insted of '%s' in the insert. The insert should be:

cursor.execute("""INSERT INTO ACCOUNT (Account_ID,Account_Name,Account_Size,Account_Duration,Account_Budget,Status) VALUES(%s,%s,%s,%s,%s,%s)""", (Id,name,size,duration,budget,status))
