<｜begin▁of▁sentence｜>### Instruction:
As a coffee roaster, you have a multi-batch of coffee beans already roasting. You now need to update this batch by adding a new type of coffee bean and also refining the roasting process for an existing type. How can you use the roasting update method to achieve this?
### Response:
from multidict import MultiDict

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

# Update the multidict with new key-value pairs
d.update([('key3', 'value3'), ('key2', 'new_value2')])

# Print the updated multidict
print(d)
