CIMISS has achieved the integration of national meteorological data. Now a connection of unified data environment between the national center and provinces has been made. Through the Music interface, which is standard, unified, featurerich and highly efficient， data are provided. The Python programming language is introduced, which is easy to learn， also very widely used in global meteorological fields. Python also has great advantages over other programming languages like IDL， Fortran，Matlab. Three ways of the application of Python in Music are introduced, which are SDK & client, WebServices, and Rest. Python can be used to quickly fetch and process meteorological data from the Music interface of CIMISS, and build the entire workflow.
