How to check the class attributes/member variable values while debuging in 'PythonWin'?.

I need to watch all the member varibales values of a class ,given the object or etc.

This is what I use to check the contents of an instance dictionary:

def formatDict(hdr_str, dd):
    listCopy = dd.keys()
    listCopy.sort()
    maxLen = max([len(i) for i in listCopy])
    return '%s%s%s' % (hdr_str, "\n", ''.join(["Key = %s %s Value = %s\n" % \
           (i, " " * (maxLen - len(i)) + "  ", dd[i]) for i in listCopy]))
 
a = YourClass()
print formatDict("\nObject Attributes:", a.__dict__)

HTH :)

Thanks for the reply,

It is not a dictionary,it is a class attributes.Whic h I would like to watch in the Debug window of the python

I always debug with print statements. To check the status of class attributes, you can do something like this:

class Demo:
    a1 = 1
    a2 = 2
    def __init__(self, data={}):
        self.data = data
    def chk_att(self):
        for item in ['a1', 'a2']:
            print '%s = %s' % (item, eval('Demo.%s' % item))
 
 
print '\n'.join(['%s = %s' % (item, eval('Demo.%s' % item)) for item in dir(Demo) if item in ['a1', 'a2']])
print
a = Demo([1,2,3,4])
a.chk_att()
 
print
 
Demo.a2 = 5000
print '\n'.join(['%s = %s' % (item, eval('Demo.%s' % item)) for item in dir(Demo) if item in ['a1', 'a2']])
print
a.chk_att()

>>> a1 = 1
a2 = 2
 
a1 = 1
a2 = 2
 
a1 = 1
a2 = 5000
 
a1 = 1
a2 = 5000
>>>

Since I don't use PythonWin (or any other debugger), I use the inspect module:

>>> import inspect
>>> class aClass:
...     aValue = 1
...     bValue = 'test'
...     
>>> anInstance = aClass()
>>> print [(name, value) for name, value in inspect.getmembers(anInstance) if not name.startswith("_")]
[('aValue', 1), ('bValue', 'test')]
>>>
