在Python中用字典解压缩元组

Question

I have a tuple with multiple dictionaries and I wish to unpack them for further use.

Let's say I have this:

tuple_to_add = {'name': 'custom1', 'value': 'first value'},{'name': 'custom2', 'value': 'second value'}

And I'd like to iterate through them I tried something like that but it didn't give me my answer:

    for value, name in tuple_to_add:
       print(value)
       print(name)

Answer 1

Dictionaries can't be unpacked in a way tuples and lists can. If you had a tuple of tuples, your way of printing would work just fine:

tuple_to_add = ('custom1', 'first value'), ('custom2', 'second value')
for name, value in tuple_to_add:
    # do whatever you want

You can simply iterate over the tuple and get the actual dictionary objects which you can use to get all the necessary information:

for dc in tuple_to_add:
    print(dc['value'])
    print(dc['name'])
