Suppose I define a class with a number of variables defined as
properties. Something like:
class MyClass(object):
def __init__(self):
self.some_variable = 42
self._a = None
self._b = "pi"
def get_a(self):
return self._a
def set_a(self, value):
self._a = value
def get_b(self):
return self._b
def set_b(self, value):
self._b = value
a = property(get_a, set_a, None, "a is a property")
b = property(get_b, set_b, None, "b is a property")
Is there a way to write a method that would list automatically all the
variables defined as a property (say by printing their docstring and/
or their value), and only those variables?

This is off the cuff. There's likely a better way.
for k, v in MyClass.__dict__.iteritems():
if isinstance(v, property):
print k, v.__doc__

The only way I could get this to work was to change the way the properties were defined/initalized:
#!/usr/bin/python
class MyClass(object):
def __init__(self):
self.some_variable = 42
self._a = None
self._b = "pi"
self.a = property(self.get_a, self.set_a, None, "a is a property")
self.b = property(self.get_b, self.set_b, None, "b is a property")
def get_a(self):
return self._a
def set_a(self, value):
self._a = value
def get_b(self):
return self._b
def set_b(self, value):
self._b = value
test = MyClass()
for k,v in test.__dict__.iteritems():
if isinstance(v, property):
print k, v.__doc__

The only way I could get this to work was to change the way the
properties were defined/initalized:
That's because you iterate over the instance's `__dict__` and not over the
*class* `__dict__` like Neil does.

I would iterate over dir(MyClass) instead - only because I prefer to hide
such implementation details.

Thank you, this solved my problem nicely.
