Are you looking for the getattr
built-in function?
Getting a parameter from class object with no '__getitem__' attribute?
Pergunta
I am using pyproj.Geod
to calculate geographic distances, and I would like to use the diameter of the earth defined by the object for another calculation.
When there is no __getitem__
attribute and the object is not indexable, is there a way of extracting a value from it?
Calling the object:
import pyproj
g = pyproj.Geod(ellps='WGS84') # Use WGS84 ellipsoid
Trying to call it by parameter name:
print g['a'] # the diameter parameter
TypeError: 'Geod' object has no attribute '__getitem__'
Testing indexing:
print g[0]
TypeError: 'Geod' object does not support indexing
Update: Calling print dir(g)
:
print dir(g)
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_fwd', '_inv', '_npts', 'a', 'b', 'es', 'f', 'fwd', 'initstring', 'inv', 'npts', 'sphere']
