Question

I have the following object

class LidarPropertiesField(object):
    osversion = ''
    lidarname = ''
    lat = 0.0
    longit = 0.0
    alt = 0.0
    pitch = 0.0
    yaw = 0.0
    roll = 0.0
    home_el = 0.0
    home_az = 0.0
    gps = 0
    vad = 0
    ppi = 0
    rhi = 0
    flex_traj = 0
    focuse = 0
    type = 0
    range_no = 0
    hard_target = 0
    dbid = 0

Also I have a dictionary with the same fields, is it possible to compare the object fields with the dictionary fields in a for loop?

Answer 1

Assuming the dict is called d, this will check if LidarPropertiesField has the same values as d for all keys in d:

for k, v in d.iteritems():
     if getattr(LidarPropertiesField, k) != v:
         # difference found; note, an exception will be raised
         # if LidarPropertiesField has no attribute k

Alternatively, you can convert the class to a dict with something like

dict((k, v) for k, v in LidarPropertiesField.__dict__.iteritems()
            if not k.startswith('_'))

and compare with ==.

Note the skipping over all class attributes that start with _ to avoid __doc__, __dict__, __module__ and __weakref__.
