How can I extract all values from a dictionary in Python?

Question

I have a dictionary d = {1:-0.3246, 2:-0.9185, 3:-3985, ...}.

How do I extract all of the values of d into a list l?

Answer 1

d = <dict>
values = d.values()

Answer 2

If you want all of the values, use this:

dict_name_goes_here.values()

If you want all of the keys, use this:

dict_name_goes_here.keys()

IF you want all of the items (both keys and values), I would use this:

dict_name_goes_here.items()

Answer 3

Pythonic duck-typing should in principle determine what an object can do, i.e., its properties and methods. By looking at a dictionary object one may try to guess it has at least one of the following: dict.keys() or dict.values() methods. You should try to use this approach for future work with programming languages whose type checking occurs at runtime, especially those with the duck-typing nature.

Answer 4

If you only need the dictionary keys 1, 2, and 3 use: your_dict.keys().

If you only need the dictionary values -0.3246, -0.9185, and -3985 use: your_dict.values().

If you want both keys and values use: your_dict.items() which returns a list of tuples [(key1, value1), (key2, value2), ...].

Answer 5

If you want all of the values, use this:

dict_name_goes_here.values()
