How to use python module to create a table and select a specific data from the said table?

Question

I am trying to create a python3 module in Sqlite. The goal is to call the module and create a table with 10 rows. Each row should contain only one number (1-10). Once called up, I wish the module (called E4.py) to provide the largest number in the table. So far, I have written the following code:

  import sqlite3
    
    db = sqlite3.connect("Exercise4.db")
    db.isolation_level = None
    
    db.execute("DROP TABLE Exc4")
    db.execute("CREATE TABLE Exc4 (x INTEGER)")
    
    for i in range(1,10+1):
            db.execute("INSERT INTO Exc4 (x) VALUES(?)",(i+1))
            Largest  = db.execute("SELECT MAX(x) FROM Exc4").fetchone()[0]
            print(Largest)
            i = i + 1

When I call for the module in command prompt by "python3 E4.py", I get an error message "ValueError: parameters are of unsupported type".
