I hase test class:
class Foo_class:
def __init__(self,x=0):
"""init, x defaul as 0."""
self.x=x
def val(self):
return self.x
I want to understand, how can call:
f=Foo_class()
print(f.val)
That f.val will return value of def f.val().
Is it possible?
class Foo_class:
def __init__(self,x=0):
"""init, x defaul as 0."""
self.x=x
@property
def val(self):
return self.x
test = Foo_class()
test.val
In case you're wondering what's going on: This is basically a nicer version of getters and setters as java people use them. There if you write a class you're supposed to never expose instance variables but have a method for getting/setting values so you can change what's going on under the hood without breaking code that's working with it. In python exposing things is fine since you can use this.
property is a special and confusing decorator in Python and some explanations (possibly some links) will greatly improve the answer. Nevertheless, this question is a duplicate and shouldn't be answered anyway...
propertyf.valwill return the address of that method object in the class as follows,<bound method Foo_class.val of <__main__.Foo_class object at 0x000002A1D9098160>>self.val = xin the__init__... ;)
