Invalid value specified for connection string attribute

import pyodbc as po    

connection_string = """
driver=ODBC Driver 17 for SQL Server;
server=SHADOW-LN4F5NUO;
database=FBI_Crime_Data;
trusted_connection=True;
"""

connection = po.connect(connection_string)

Output:

According to this microsoft documentation, recognized values are yes and no

pyodbc documentation says, you can use your Windows account for authentication instead of username/password by providing Trusted_Connection attribute as: Trusted_Connection=yes

So it looks the connectionstrings sql server main page shows you the connection string for .Net libraries. If you click on any of the pages for a specific version of the driver under "ODBC drivers" (like 17 or 13 or 11), it shows Trusted_Connection=yes

For [ODBC Driver 17 for SQL Server] driver
It should be like 
connection_string = "
driver=ODBC Driver 17 for SQL Server;
server=SHADOW-LN4F5NUO;
database=FBI_Crime_Data;
trusted_connection=yes;
"""

For [SQL SERVER DRIVER]
It should be like :

connection_string = "
driver=SQL SERVER DRIVER;
server=SHADOW-LN4F5NUO;
database=FBI_Crime_Data;
trusted_connection=True;
"
