Connect to SQL Server Express Database with Python (Windows Authentication)
<p>I've got a Java Program connected to my SQLServer Express Database. The code I used to connect is:</p>

<pre><code>Connection con = null;
try {   
    String url = "jdbc:sqlserver://GANESHA\\SQLEXPRESS:1434;databaseName=4YP;integratedSecurity=true";
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    con = DriverManager.getConnection(url);
}
</code></pre>

<p>I have since decided to use Python instead but can't seem to get it to connect to my database. The code I've been using is:</p>

<pre><code>import pyodbc

con_str = (
    r'Driver = {SQL SERVER};'
    r'Server = .\GANESHA;'
    r'Database = 4YP;'
    r'TrustedConnection = yes;'
)
cnxn = pyodbc.connect(con_str)
</code></pre>

<p>The error I'm getting is: "pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')"</p>
