How to access attribute within a list of dicts in python?

Question

Assume I have a dict:

firstdict = {"somelist":[]}

I have another dict:

  seconddict = {"attribute1": "value1", "attribute2": "value2"}

After appending the dictionary

firstdict["somelist"].append(seconddict)

I want to print the "attribute1" value. Though the following statement is not working:

print firstdict["somelist"][0].attribute1

How to I print/access the value of attribute1?

Answer 1

>>> firstdict = {"somelist":[]}
>>> seconddict = {"attribute1": "value1", "attribute2": "value2"}
>>> firstdict["somelist"].append(seconddict)
>>> print firstdict["somelist"][0]['attribute1']
value1

Answer 2

it's firstdict["somelist"][0]['attribute1']

Answer 3

Python is not JavaScript; "attribute1" is no attribute, it is the key in the dictionary. To access the corresponding value, you use the [] indexing operator, just like you did with firstdict:

subdict = firstdict["somelist"][0]
print subdict["attribute1"]

or, simply:

print firstdict["somelist"][0]["attribute1"]

Answer 4

firstdict["somelist"][0]['attribute1']

Answer 5

It seems weird to be storing dictionaries inside of a list inside of a dictionary. If you're using this to collect values from multiple dictionaries checkout this thread.

You might also consider nesting dictionaries:

>>>seconddict = {"key1": "value1", "key2": "value2"}
>>>firstdict = {'dict 1': seconddict}
>>> firstdict['dict 1']['key1']
'value1'
