    ...:
    ...: {'name': 'mei', 'age': '27', 'hometown': 'NY', 'gender': 'female'},
    ...: {'name': 'smith', 'age': '14', 'hometown': 'NY', 'gender': 'male'},
    ...: {'name': 'raj', 'age': '13', 'hometown': 'IND', 'gender': 'male'}]

In [13]: [i for i in a if i["hometown"]=="NY"]
Out[13]:
[{'name': 'mei', 'age': '27', 'hometown': 'NY', 'gender': 'female'},
 {'name': 'smith', 'age': '14', 'hometown': 'NY', 'gender': 'male'}]

Answer 2

You can try this:

result = [{'name': 'paul', 'age': '26', 'hometown': 'AU', 'gender': 'male'},
{'name': 'mei', 'age': '27', 'hometown': 'NY', 'gender': 'female'},
{'name': 'smith', 'age': '14', 'hometown': 'NY', 'gender': 'male'},
{'name': 'raj', 'age': '13', 'hometown': 'IND', 'gender': 'male'}]

a=[]
for i, test in enumerate(result):
    for key,value in test.items():
        if key == 'hometown':
            if 'NY' in value:
                a.append(result[i])
print(a)

output:

[{'name': 'mei', 'age': '27', 'hometown': 'NY', 'gender': 'female'}, {'name': 'smith', 'age': '14', 'hometown': 'NY', 'gender': 'male'}]
