Note:

When creating a logger as shown below, it propagates its log messages to root logger, i.e if logger is defined inside a module, which is imported by other file in which logging is defined using basicConfig.All the messages of logger are propagated to logging, because logging.getLogger(__name__),has 1 additional field Propagate, whose default value is set to true.We need to explicitly set it to false to stop propagation

logger = logging.getLogger(__name__)
