[SQL] Connecting to Microsoft SQL server using Python

I am trying to connect to SQL through python to run some queries on some SQL databases on Microsoft SQL server. From my research online and on this forum the most promising library seems to be pyodbc. So I have made the following code

import pyodbc
conn = pyodbc.connect(init_string="driver={SQLOLEDB}; server=+ServerName+;
database=+MSQLDatabase+; trusted_connection=true")
cursor = conn.cursor()


and get the following error

Traceback (most recent call last):
File "C:\Users...\scrap.py", line 3, in <module>
conn = pyodbc.connect(init_string="driver={SQLOLEDB}; server=+ServerName+; database=+MSQLDatabase+; trusted_connection=true")
pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')


I have looked at the folowing posts and tried changing my driver to {sql server} and have connected using ODBC links before in SAS, which is partially what my above code is based on, so don't think I need to install anything else.

pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')

Pyodbc - "Data source name not found, and no default driver specified"

Thanks
