Hi,
Hereafter is an example using super.
At the execution, we obtain:
coucou
init_coucou2
coucou1
coucou2
Traceback (most recent call last):
File "essai_heritage.py", line 34, in <module>
print b.a
AttributeError: 'coucou' object has no attribute 'a'
Why Python does not enter in the __init__ method of coucou1?
If I replace the two lines using "super" by the two following lines, it
works perfectly:
coucou1.__init__( self )
coucou2.__init__( self )
##########
class coucou1( object ):
def __init__( self
, a = 1 ):
self.a = a
print "init_coucou1"
def print_coucou1( self ):
print "coucou1"
class coucou2( object ):
def __init__( self
, b = 2 ):
self.b = b
print "init_coucou2"
def print_coucou2( self ):
print "coucou2"
class coucou( coucou1, coucou2 ):
def __init__( self ):
print "coucou"
super( coucou1, self ).__init__( )
super( coucou2, self ).__init__( )
b = coucou()
b.print_coucou1()
b.print_coucou2()
print b.a
print b.b
