Hello List,
I would like to make a singleton class in python 2.4.3, I found this
pattern in the web:
class Singleton:
__single = None
def __init__( self ):
if Singleton.__single:
raise Singleton.__single
Singleton.__single = self
the line "raise Singleton.__single" invokes in my class the following
error:
exceptions must be classes, instances, or strings (deprecated), not
