Python - close file and IOError

Question

I'm writing a prog which writes data into a file, and each hour a new file is generated, with a precise title. When the storage is full, it either stops the application, or deletes the oldest file created in the folder.

fp = open (fileNamePath, 'a')
fp.write('%s' % buffer)
try:
    fp.close()
except IOError:
    # delete file or close app

But when it comes to the except, it just skips it, and display IOError.

Thanks !

Answer 1

So if I understand it correctly, IOError is not catching exception but it is exploding. Did you try some more generic exception ('except Exception')?

Or you can try workaround with finally instead of except part:

finally:
    if not f.closed:
        # handle exception here

Answer 2

I looked for solution on Google, and someone suggested to use :

try:
    with open(filePath,'a') as fp:
        fp.write('%s' % buffer)

except IOError as exc:
    # Handling exception

Well I don't get why but it works that way.

Thanks all !
