Kedro is an open-sourced Python framework for creating maintainable and modular data science code.

Kedro

Is there a way in kedro in which I can overwrite the info.log file every time it executes. Currently it is appending new run logs.

you will need to change the type of logger it is using.

```  info_file_handler:
    class: logging.handlers.RotatingFileHandler
    level: INFO
    formatter: simple
    filename: info.log
    maxBytes: 10485760 # 10MB
    backupCount: 20
    encoding: utf8
    delay: True```
This is the default

Do you need to overwrite the file completely? Or you want to keep the record having `info1.log`, `info2.log` etc?

or you could use an `after_pipeline_run` hook to just truncate the file

I guess it is as simple as changing `mode: w` , I haven’t tested though

```  info_file_handler:
    class: logging.handlers.RotatingFileHandler
    level: INFO
    formatter: simple
    filename: logs/info.log
    maxBytes: 10485760 # 10MB
    backupCount: 20
    encoding: utf8
    delay: True
    mode: w```
i tried this, but still it is appending the logs.

No Kedro magic is involved, all pure python `logging`. I just tried and it works. Thanks for asking the question I didn’t know this before too :slightly_smiling_face:

The simple solution is don’t use `RotatingFileHandler`, use the basic one.
```  info_file_handler:
    class: logging.FileHandler
    level: INFO
    formatter: simple
    filename: info.log
    delay: True
    encoding: utf8
    mode: w```
