[python]logging module logs duplicate issues after using Basicconfig

Logging.basicconfig configuration logging to file A, and then using Logging.filehandler to generate records to file B logger

When using this logger log, both files A and B are logged simultaneously, and it feels like the mechanism is quite unexpected.

#-*-Coding:utf8-*-import logginglogging.basicconfig (        level=logging. DEBUG,         format= ' [% (asctime) s][% (process) d:% (thread) d][% (levelname) s]% (message) s ',                                           filename= "Main.log",        filemode= ' A + ') _logger = Logging.getlogger (' aaa.log ') fh = logging. Filehandler (' Aaa.log ') fh.setlevel (logging. DEBUG) Formatter1 = logging.
