Best way to pop many elements from a Python dict

Question

This is my code:

a = dict(aa='aaaa', bb='bbbbb', cc='ccccc', ...)
print(a.pop(['cc', ...]))

but this raises an error. What is the best simple way to pop many elements from a python dictionary?

Answer 1

How about the simple:

for e in ['cc', 'dd',...]: 
  a.pop(e)

Answer 2

Using list comprehension:

a = {'key1':'value1','key2':'value2','key3':'value3'}
print [a.pop(key) for key in ['key1', 'key3']]

Answer 3

If I understand correctly what you want, this should do the trick:

print [a.pop(k) for k in ['cc', ...]]

Be careful, though, because pop is destructive, i.e. it modifies your dictionary.
