Hi,
I'm wondering where the most appropriate location is to cleanup class
objects. For example, i have a file handle as an instance attribute in one
of my classes and I need to call f.close() on it when the class object falls
out of scope. Any ideas? I've tried __del__() but I don't remember this
working for some reason. I might try it again later just to be positive.
Below is the source code to the class I'm attempting to add a destructor to:
import struct
#########################################################
class fout:
def __init__( self, filename ):
self._file = open( filename, "wb" )
def write32( self, data ):
# write out a 32-bit integer value
self._file.write( struct.pack( "I", data ) )
def write16( self, data ):
# write out a 16-bit integer value
self._file.write( struct.pack( "H", data ) )
def write8( self, data ):
# write out an 8-bit integer value
self._file.write( struct.pack( "B", data ) )
def write( self, data ):
# write out a string literal
self.write32( len( data ) )
self._file.write( data )
self._file.flush()
