So in this example:
class Person(object):
def __init__(self, name):
self._name = name
[...]
name = property(getName, setName, delName, "name property docs")
(3) name is the public attribute that other classes or functions are
permitted to use.
problem 1: there is no self.name = something in the defination ,why i can get
bob.name?
class Person(object):
def __init__(self, name):
self._name = name
def getName(self):
print('fetch....')
return self._name
def setName(self, value):
print('change...')
self._name = value
def delName(self):
print('remove....')
del self._name
name = property(getName, setName, delName, "name property docs")
>>> bob=Person("dear bob")
>>> bob._name # there is a defination in class Person ,self._name =
name ,when we initial it ,we can get bob._name
'dear bob'
>>> bob.name #there is no defination in class Person ,self.name=name
,why we can get the value of bob.name?
fetch....
'dear bob'
problem 2: what is the meaning of
name = property(getName, setName, delName, "name property docs") ?
why i can not write _name = property(getName, setName, delName, "name property
docs") ?
class Person(object):
def __init__(self, name):
self._name = name
def getName(self):
print('fetch....')
return self._name
def setName(self, value):
print('change...')
self._name = value
def delName(self):
print('remove....')
del self._name
_name = property(getName, setName, delName, "name property docs")
bob=Person("dear bob")
I got error from the codes:
File "<stdin>", line 9, in setName
File "<stdin>", line 8, in setName
