Question

Is there any method to let me know the values of an object’s attributes?
For example,
info = urllib2.urlopen('http://www.python.org/')
I wanna know all the attributes’ values of info. Maybe I don’t know what are the attributes the info has. And str() or list() can not give me the answer.

Answer 1

To get all the names of object’s attributes, use dir(obj). To get their values, use getattr(obj, attr_name). You could print all the attributes and their values like so:

for attr in dir(obj):
    print(attr, getattr(obj, attr))

If you don’t need the built-in attributes, such as __str__ etc, you can simply use obj.__dict__, which returns a dictionary of object’s attributes and their values.

for k in obj.__dict__:
    print(k, obj.__dict__[k])
