Frequently Asked Questions

Is logging to a single file thread-safe in Python?

Although logging is thread-safe, and logging to a single file from multiple threads in a single process is supported, logging to a single file from multiple processes is not supported, because there is no standard way to serialize access to a single file across multiple processes in Python.

How to configure logging in Python?

Programmers can configure logging in three ways: Creating loggers, handlers, and formatters explicitly using Python code that calls the configuration methods listed above. Creating a logging config file and reading it using the fileConfig () function. Creating a dictionary of configuration information and passing it to the dictConfig () function.

Can I log to a single file from multiple processes?

Use the techniques outlined in Logging to a single file from multiple processes to circumvent such issues. While there might be unusual cases where you’ll need to do this, in general there is no point because loggers are singletons.

How many loggers should I use in Python?

Python’s logging documentation recommends that you should only attach each handler to one logger and rely on propagation to apply handlers to the appropriate child loggers.
