writing a log file from python program

Question

I want to output some strings to a log file and I want the log file to be continuously updated. I have looked into the logging module pf python and found out that it is mostly about formatting and concurrent access. Please let me know if I am missing something or amy other way of doing it

Accepted Answer

usually i do the following:

```
  # logging  
  LOG = "/tmp/ccd.log"                                                     
  logging.basicConfig(filename=LOG, filemode="w", level=logging.DEBUG)

# console handler  
  console = logging.StreamHandler()  
  console.setLevel(logging.ERROR)  
  logging.getLogger("").addHandler(console)
```

The logging part initialises logging's basic configurations. In the following I set up a console handler that prints out some logging information separately. Usually my console output is set to output only errors (logging.ERROR) and the detailed output in the LOG file.

Your loggings will now printed to file. For instance using:

```
logger = logging.getLogger(__name__)
logger.debug("hiho debug message")
```

or even

```
logging.debug("next line")
```

should work.
