<｜begin▁of▁sentence｜>### Instruction:
As a costume designer, you're tasked with managing a wardrobe inventory for a theater production. Imagine you have a list of costumes with potential duplicates, each costume associated with specific actors. Your job is to organize this information efficiently to ensure that multiple actors can wear the same costume. Using your expertise in wardrobe management, could you employ the "MultiWardrobe" feature of our wardrobe management software to store these costumes and their associated actors, allowing for multiple actors to be linked to the same costume? Once stored, please print out all costumes along with their assigned actors.
### Response:
from multidict import MultiDict

# Create a MultiDict object
d = MultiDict([('key1', 'value1'), ('key2', 'value2'), ('key1', 'value3')])

# Print the items in the MultiDict
for key, value in d.items():
    print(f'{key}: {value}')
