Pass Arguments to Function

[phillyfa]

Hello,

The following function creates a connection string to a SQL Server instance. I have another program where all the values are hard-coded into the connection string. However, I'm toying around with different scenarios and would like to create a generic connetion string where arguments for host, database, username, etc could be passed to the function when it's called.

Here's what I have so far:

import pyodbc

'''
Connect to the database by the given credentials
'''
def connect_to_database(driver, host, database):
    try:
        conn = pyodbc.connect('DRIVER='+driver+'; SERVER='+host+'; DATABASE='+database+';trusted_connection=yes;')
        return conn
    except Exception as e:
        print ("Error while connecting to database", e)

connect_to_database("SQL Server", "MJ0", "AdventureWorks2012")

But I'm receiving the following error:

Error:
    server (str) = "MJ0"
    ^
SyntaxError: cannot assign to function call
