# How To Write Logs To A File With Python?

If you are new to logging in Python, please feel free to start with our [Introduction to Python logging](https://betterstack.com/community/guides/logging/how-to-start-logging-with-python/) to get started smoothly. Otherwise, here is how to write logs to a file in Python:

## Using Basic Configuration

You can use basic config. If you configure the attribute `filename`, logs will
be automatically saved to the file you specify. You can also configure the
attribute `filemode`. Setting the value to `w` will overwrite the file after
every entry.

```python
import logging

logging.basicConfig(filename="logs.log", filemode="w", format="%(name)s → %(levelname)s: %(message)s")

logging.warning("warning")

OUTPUT
root → WARNING: warning
```

## Using Provided Classes

You can also use the provided classes - loggers and handlers:

```python
logger = logging.getLogger(__name__)
FileOutputHandler = logging.FileHandler('logs.log')

logger.addHandler(FileOutputHandler)

logger.warning("Warning.")
```

You will create a logger and a handler. When creating a handler, assign the
class `FileHandler` and a file name as an attribute. Then set the handler to a
logger:

```
[output]
Warning.
```

If you would like to have more options when it comes to logging your apps, have a look at our [Guide to logging with Loguru](https://betterstack.com/community/guides/logging/loguru/), which is the most popular third-party logging framework for Python.
