Can you help me write a python function to update the status of a customer's order in an SQLite database. There are two tables: orders which has orderID (Primary Key), customerID (Foreign Key), orderDate, orderTotal, and orderStatus. There is also a customer table: customerID (Primary Key), customerName, customerAddress, customerEmail. The function should take orderStatus and orderID as inputs.

Sure, here's an example of a Python function that updates the status of a customer's order in an SQLite database:

```
import sqlite3

def update_order_status(order_status, order_id):
    conn = sqlite3.connect("database.db")
    cursor = conn.cursor()
    
    update_query = "UPDATE orders SET orderStatus = ? WHERE orderID = ?"
    cursor.execute(update_query, (order_status, order_id))
    
    conn.commit()
    conn.close()
    
    return "Order status updated successfully"```

In this function, we first import the sqlite3 module. Then, we define a function `update_order_status` that takes two inputs: `order_status` and `order_id`.

Next, we create a connection to the SQLite database and get a cursor to execute the queries. We then create an update query to update the `orderStatus` of the order with the given `order_id`. We use the execute method to execute the query with the given parameters.

Finally, we commit the changes to the database and close the connection. The function returns a message indicating that the order status was updated successfully.

How do I create "database.db" or will the program create it for me?

The `database.db` file will not be created automatically by the program. You need to create the database file manually before running the function.

You can create the database file using the following code:

```python
import sqlite3

conn = sqlite3.connect("database.db")
cursor = conn.cursor()

# create orders table
create_orders_table = """
CREATE TABLE IF NOT EXISTS orders (
    orderID INTEGER PRIMARY KEY,
    customerID INTEGER,
    orderDate TEXT,
    orderTotal REAL,
    orderStatus TEXT,
    FOREIGN KEY (customerID) REFERENCES customer(customerID)
);
"""
cursor.execute(create_orders_table)

# create customer table
create_customer_table = """
CREATE TABLE IF NOT EXISTS customer (
    customerID INTEGER PRIMARY KEY,
    customerName TEXT,
    customerAddress TEXT,
    customerEmail TEXT
);
"""
cursor.execute(create_customer_table)

conn.commit()
conn.close()```

This code creates the `database.db` file and two tables orders and customer. The orders table has five columns: `orderID`, `customerID`, `orderDate`, `orderTotal`, and `orderStatus`. The customer table has four columns: `customerID`, `customerName`, `customerAddress`, and `customerEmail`. The `customerID` column in the orders table is a foreign key that references the `customerID` column in the customer table.
