Python: do I need a Singleton?

I've multiple instanciated logger classes in logger.py which I import in multiple other modules.

logger.py

class Logger:
    def __init__(self, name='default'):
        # create a Logger with custom handlers
        # ...

main_logger = Logger('main_logger')
another_topic_logger = Logger('another_topic_logger')

module_a.py

from logger import main_logger
main_logger.info('hello!')

How does Python handle it in the background? Do I need a Singleton wrapper or is that just fine?
