How do I figure out the correct DRIVER string for ODBC SQL connection (in python)

I have a python script that is using sqlAlchemy to connect to a SQL Server DB. We moved the DB from a local server in the closet to AWS.
When running from a mac, I have:
'DRIVER=/usr/local/lib/libtdsodbc.so',
and that works for both closet and AWS
on a Windows machine, for the closet the connection contained:
'DRIVER=SQL Server',
which gives the error message:
(pyodbc.Error) ('HY000', '[HY000] [Microsoft][ODBC SQL Server Driver]Cannot generate SSPI context (0) (SQLDriverConnect); [HY000] [Microsoft][ODBC SQL Server Driver]Cannot generate SSPI context (0)')
searching around, tells me that maybe I need a new driver, so:
https://github.com/mkleehammer/pyodbc/wiki/Connecting-to-SQL-Server-from-Windows recommends:
'DRIVER={{ODBC Driver 18 for SQL Server}}'
(Because I'm formatting into the connection string, so I need to escape the {})
gives:
sqlalchemy.exc.DBAPIError: (pyodbc.Error) ('IM012', '[IM012] [Microsoft][ODBC Driver Manager] DRIVER keyword syntax error (0) (SQLDriverConnect)')
alternatively,
'DRIVER=ODBC Driver 18 for SQL Server',
gives:
(pyodbc.InterfaceError) ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
This SQLAlchemy engine works:
Engine(mssql+pyodbc://cam-tls1:1433/services_vars?driver=SQL Server)
This one does not:
Engine(mssql+pyodbc://P-CEP-SQL:1433/services_vars?driver={ODBC Driver 18 for SQL Server})
it gives a syntax error on the DRIVER keyword...
Do I need to download a new library? or do I need to specify the driver differently?

I'm still not exactly sure how I was SUPPOSED To find this out, but this works:
'DRIVER=ODBC+Driver+17+for+SQL+Server',
even though 18 appears to be current, it doesn't work for 18. but it does work for 17.

how do I fix this pyodbc Driver syntax error

I'm using SQLAlchemy in python on a windows machine to connect to a SQL Server. I'm pretty sure that I am generating the SQL engine correctly, I have:
Engine(mssql+pyodbc://P-CEP-SQL:1433/services_vars?driver={ODBC Driver 18 for SQL Server})
A previous version, connecting to a different copy of the same server works with:
Engine(mssql+pyodbc://cam-tls1:1433/services_vars?driver=SQL Server)
however, with the Driver 18 line, I'm now getting:
sqlalchemy.exc.DBAPIError: (pyodbc.Error) ('IM012', '[IM012] [Microsoft][ODBC Driver Manager] DRIVER keyword syntax error (0) (SQLDriverConnect)')
when I remove the {} I get:
sqlalchemy.exc.InterfaceError: (pyodbc.InterfaceError) ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
Which I'm pretty sure means that it can't find the driver....
It gives this for any string with { } in it, but I'm pretty sure that that's the correct name of the driver. Do I need to extra escape something?

The correct syntax appears to be:
'DRIVER=ODBC+Driver+17+for+SQL+Server',
This works for version 17, but not 18 for some reason.

InterfaceError: Data source name not found and no default driver specified (0) (SQLDriverConnect)

This question has been asked before (see link below) but I'm still having issues even though both my Python and MS Office are 64-bit. After ensuring both are 64-bit, I tried running the following code:
conn = pyodbc.connect(r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=Q:\Data Requests\Boarding.accdb;')
but still got the following error:
InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
Also of note, I am able to connect and pull data into Python from my SQL server just fine using this code:
conn = pyodbc.connect('Driver={SQL Server};'
'Server=ENTSNR;'
'Database=EMData;'
'Trusted_Connection=yes;')
PYODBC--Data source name not found and no default driver specified

getting error in establishing a database connection (pyodbc)

I am trying to use pyodbc with sql server. However I am getting the following error:
InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified (0)
(SQLDriverConnect)').
This is my connection code
odbc_conn_str= 'DRIVER= {Microsoft Access Driver (*.mdb)}; DBQ=%s' %db_file
conn= pyodbc.connect(odbc_conn_str)

You are saying you are trying to connect to an SQL server but using a Microsoft Access Driver. Only use a Microsoft Access Driver if connecting to an Access Database/File.
Try the following, this is why I use to connect to a Microsoft SQL Server:
sql_connection = pyodbc.connect('DRIVER={SQL Server};SERVER=IPADDRESS\SQLSERVERINSTANCE;DATABASE=DBNAME;UID=USERNAME;PWD=PASSWORD;Trusted_Connection=no;')
Microsoft have a doc on setting up pyodbc for Microsoft SQL Server: https://learn.microsoft.com/en-us/sql/connect/python/pyodbc/python-sql-driver-pyodbc?view=sql-server-ver15

Anyone know how to solve this error? Trying to connect to Azure SQL Server.
Thanks a ton!
InterfaceError: (pyodbc.InterfaceError) ('IM002', u'[IM002]
[Microsoft][ODBC Driver Manager] Data source name not found and no
default driver specified (0) (SQLDriverConnect)') (Background on this
error at: http://sqlalche.me/e/rvf5)

Without your code, but just from the error message, it seams that there is some issue with your connection string.
You can use the code below for test:
import pyodbc
from sqlalchemy import create_engine
import urllib
params = urllib.quote_plus \
(r'Driver={ODBC Driver 13 for SQL Server};Server=tcp:yourDBServerName.database.windows.net,1433;Database=dbname;Uid=username#dbserverName;Pwd=xxx;Encrypt=yes;TrustServerCertificate=no;Connection Timeout=30;')
conn_str = 'mssql+pyodbc:///?odbc_connect={}'.format(params)
engine_azure = create_engine(conn_str,echo=True)
print('connection is ok')
Hope it helps. And please let me know if any further issue.
