将字典列表转换为字典

Question

How could in convert a list of dict to a dict of dict .

This is the list I have:

data = [{'id': '7249722264','title':'test'}, {'id': '111','test':'te11111st'}]

I have to pass this dataset to an api that accept data in this format:

api_data = {'fields': {'id': '72497264', 'title': 'test'}}

I need to loop through the element present in the data list and pass it to api like this:

for each record in the list:

new_dict = {'fields': {'id': '72497264', 'title': 'test'}}
api.post(new_dict)

How I can achieve this? Thanks

You can do it like so with a for loop:

data = [{'id': '7249722264','title':'test'}, {'id': '111','test':'te11111st'}]
new_dict = {}
for e, i in enumerate(data):
  new_dict['fields'+str(e)] = i

print(new_dict)

>>> {'fields0': {'id': '72497264', 'title': 'test'}, 'fields1': {'id': '111','test':'te11111st'}}

But you can't name every key fields because dict keys are unique, so you would have to either make the API call each time inside the for loop, or as I've done above append an index to the key name.

Edit: Alternative dict comprehension (courtesey of Dillon Davis):

data = [{'id': '7249722264','title':'test'}, {'id': '111','test':'te11111st'}]
new_dict = {'fields{}'.format(i):x for i, x in enumerate(data)}
print(new_dict)

    >>> {'fields0': {'id': '72497264', 'title': 'test'}, 'fields1': {'id': '111','test':'te11111st'}}
