fl = list(filter(lambda x: x['first'] == 'Christian', dictlist))

# you can't use `.property` because this is a dictionary, not a object
fl[0]['last']
# returns Doppler

python filter a dictionary

d = dict(a=1, b=2, c=3, d=4, e=5)
print(d)
d1 = {x: d[x] for x in d.keys() if x not in ['a', 'b']}
print(d1)

python filter dictionary by keys

# Basic syntax:
{key: your_dict[key] for key in your_dict.keys() and {'key_1', 'key_2'}}
# Where this uses list comprehension for dictionaries to make a new dictionary
#	with the keys that are found in the set

# Example usage:
your_dict = {'key_1': 1, 'key_2': 2, 'key_3': 3}
{key: your_dict[key] for key in your_dict.keys() and {'key_1', 'key_2'}}
--> {'key_1': 1, 'key_2': 2}
