se follow code:
"""
class my_class:
a={}
def __init__(self, n):
self.a = n
def hola(self, b):
self.a["a"] = b
a1 = my_class({"a":1, "b":1})
print "a1=", a1.a
a2 = my_class({"a":1, "b":1})
a1.hola(2)
print "a2=", a2.a
print "a1=", a1.a
"""
must show:
a1= {'a': 1, 'b': 1}
a2= {'a': 1, 'b': 1}
a1= {'a': 2, 'b': 1}
but show:
a1= {'a': 1, 'b': 1}
a2= {'a': 2, 'b': 1}
a1= {'a': 2, 'b': 1}
This error happend only whit dicts, y only when de dict
atributte is defined before of the __init__ of the class

sorry the code is the folowing:
class my_class:
a={}
def __init__(self, n):
for i in n:
self.a[i] = n[i]
def hola(self, b):
self.a["a"] = b
a1 = my_class({"a":1, "b":1})
print "a1=", a1.a
a2 = my_class({"a":1, "b":1})
a1.hola(2)
print "a2=", a2.a
print "a1=", a1.a

Logged In: YES user_id=1188172 Then this is no bug. You are never assigning to self.a, thus the "a" you reference in the class's methods is the one defined as a class attribute and therefore shared between instances. |
