How to split a dictionary into single-key dictionaries?

Question

I have a dict with n keys. The problem is I don't want a single dictionary, but a list of dictionaries per single key-value pair.

For example:

d = {'a' : -15, 'b' : -71.8333, 'c' : 'a'}

The output I want:

[{'a' : -15},
 {'b' : -71.8333},
 {'c' : 'a'}]

Answer 1

You can iterate over the dict's key-value pairs using dict.items and make a new dict from each one:

d = {'a' : -15, 'b' : -71.8333, 'c' : 'a'}

dicts = []
for key, value in d.items():
    dicts.append({key: value}

Or as a list-comprehension:

dicts = [{key: value} for key, value in d.items()]

Answer 2

Try this:

d = {'a' : -15, 'b' : -71.8333, 'c' : 'a'}

for i, o in d.items():
    print({i: o})

Will give:

{'a': -15}
{'b': -71.8333}
{'c': 'a'}
