问题
I use pyodbc to connect to my local SQL database which works withoout problems.
SQLSERVERLOCAL='Driver={SQL Server Native Client 11.0};Server=(localdb)\\v11.0;integrated security = true;DATABASE=eodba;'
cnxn = pyodbc.connect(SQLSERVERLOCAL) #works
I try the connection to the azure sql database with:
SQLSERVERAZURE='Driver={SQL Server Native Client 10.0};Server=tcp:mydatbase.database.windows.net,1433;Database=mydb;Uid=myuser@myerver;Pwd=mypass;Encrypt=yes;Connection Timeout=30;'
cnxn = pyodbc.connect(SQLSERVERAZURE) #works not
what gives me the error:
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')

Besides the suggestions that provided by meet-bhagdev who recommended to use pymssql dirve that mentioned in link, to resolve the error: Data source name not found and no default driver specified (0) (SQLDriverConnect)') that encountered, please update your connect string as below to see if it works.
conn = pyodbc.connect('DRIVER={SQL Server};SERVER=yoursqlAzureServer.database.windows.net,1433', user='yourName@yoursqlAzureServer', password='Password', database='DBName')

Download ODBC driver from Microsoft website and try installing it. I guess then the problem should disappear. Here is the link: https://www.microsoft.com/en-us/download/details.aspx?id=50420
