How to get data from list with dictionary

Question

Hello I have a python variable with List plus dictionary

 >>> print (b[0])
    {'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}
-----------------------------------------------------------------------
   >>> print (b)
[{'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}]
>>>

I have tried everything But I couldn't get 'addr' extracted.

Help Please.

Answer 1

try this:

print (b[0]['addr'])

print(b[0]) gives a dictionary, in dictionary you can fetch the value by its key like dict[key] => returns its associated value.

so print(b[0]['addr']) will give you the value of addr

Answer 2

You can just use b[0]['addr']:

>>> b = [{'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}]
>>> b[0]['addr']
'127.0.0.1'

Answer 3

print list by its key

print(b[0]['addr'])

Answer 4

You can just use a print(b[0]['addr'])

Answer 5

You could use get method of dict:

>>> b[0].get('addr')
'127.0.0.1' 

From docs:

get(key[, default])
Return the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError.

Answer 6

You may use get method of dict, which works on the key, and provide the corresponding value. b[0].get('addr')
