Extract dict value from list of dict in python

Question

I have a list of dicts like this:

[{'name': 'John', 'age': 25}, {'name': 'Matt', 'age': 35} , {'name': 'Peter', 'age': 40}]

How can I get the name for those whose age is between 20-30?

Many thanks for your help.

Answer 1

You would use something like this:

dicta = {'name': 'John', 'age': 25}, {'name': 'Matt', 'age': 35} , {'name': 'Peter', 'age': 40}

for val in dicta:
  if 20 <= val['age'] <= 30:
    print(val['name'])

You seem to be new to Python so I suggest you look at some tutorials for example like this one on TutorialsPoint. Walks you through dictionaries.

Answer 2

Something like this should do it:

list_of_dicts = [{'name': 'John', 'age': 25}, {'name': 'Matt', 'age': 35} , {'name': 'Peter', 'age': 40}]
names = [d['name'] for d in list_of_dicts if 20 <= d['age'] <= 30]
