domain name and connection string to SQL Server when using Python and pyodbc

Question

when using Windows authentification with domain name and connection string to SQL Server (using Python34 and pyodbc), I still receive the following error:

cnxn = pyodbc.connect('DRIVER={SQL Server Native Client 11.0};SER
N04\SQLEXPRESS;DATABASE=BRKPNTD',UID='CZMKAJAN04\celocaladmin', PWD='xxxxxx')
pyodbc.Error: ('28000', "[28000] [Microsoft][SQL Server Native Client
Server]Login failed for user 'CZMKAJAN04\\celocaladmin'. (18456) (SQLDriverConnect)")

I don't know how to get rid of the double backslash, tried raw version of the string, various forms of escaping and nothing helped. Do you know how to solve it? Thanks a lot

SQL Server连接字符串的Windows身份验证需要Trusted_Connection参数，不能使用UID和PWD进行指定。

cnxn = pyodbc.connect('DRIVER={SQL Server Native Client 11.0};SERN04\SQLEXPRESS;DATABASE=BRKPNTD', Trusted_Connection='yes')
