Never assume. A better approach would be to experiment:
>>> a_dict = {'name':'apple', 'color':'red', 'texture':'smooth',
'shape':'sphere'}
>>> for i in a_dict: print i
color
shape
name
texture
>>> for i in a_dict.iterkeys(): print i
color
shape
name
texture
>>> for i in a_dict.itervalues(): print i
red
sphere
apple
smooth
>>> for i in a_dict.iteritems(): print i
('color', 'red')
('shape', 'sphere')
('name', 'apple')
('texture', 'smooth')
