iterate dict list comprehension

comprehension_example.py

dlist = [{'Bilbo':'Ian','Frodo':'Elijah'},
         {'Bilbo':'Martin','Thorin':'Richard'}]

k = 'Bilbo'

#this works as expected
for i in dlist:
...     if k in i:
...         i[k]
...     else:
...         'NOT PRESENT'

#it also works with this
k= 'Frodo'

#iteration goes at the end in this case!! 
[i[k] if k in i else 'NOT PRESENT' for i in dlist]
