We can see here that our method actually looks very similar to the above, but weve been able to strip out the .keys() method entirely! Find centralized, trusted content and collaborate around the technologies you use most. So I found this page while trying to optimize a thing for taking the only key in a dictionary of known length 1 and returning only the key. I have a dictionary which is decreasing order sorted by value. But there have also clearly been optimizations made (see comments for details), especially in first_1. However if you wanted to print the keys there a couple of ways to it: This method uses tuple assignment to access the key and the value. New unpacking generalizations (PEP 448) were introduced with Python 3.5 allowing you to now easily do: Unpacking with * works with any object that is iterable and, since dictionaries return their keys when iterated through, you can easily create a list by using it within a list literal. Well use dictionary indexing to get the value for the key Nik from our dictionary ages: We can see here that this worked beautifully. It is possible to define valid max instead of equal . In this, we just take the first next key using next() and iter function is used to get the iterable conversion of dictionary items.

Dictionaries are now ordered in CPython 3.6 and all other Python implementations starting with Python 3.7. They consist of key:value pairs that make finding an items value easy, if you know their corresponding key. With Python 2.7, I can get dictionary keys, values, or items as a list: How do I get a plain list of keys with Python 3? Lets see how we can access all of a dictionarys values: We can use this to see whether or not a value exists. That said, most folks probably need to be able to do both at the same time: `for key, value in dictionary.items ()`python. There can be many specific uses of it, either for checking the indexing and many more of these kinds. I have a dictionary which is decreasing order sorted by value. Note: Order is not guaranteed on versions under 3.7 (ordering is still only an implementation detail with CPython 3.6). Instead of converting to a list, use islice from the built-in itertools module, which is much more efficient since converting the keys into a list just to throw away most of it is very wasteful. Why do we kill some animals but not others? Check out some other Python tutorials on datagy, including our complete guide to styling Pandas and our comprehensive overview of Pivot Tables in Pandas! Printing out dict.keys() looks like this: We can see how that looks like a little bit like a list. New unpacking generalizations (PEP 448) were introduced with Python 3.5 allowing you to now easily do: >>> newdict = {1:0, 2:0, 3:0} >>> [*newdict] [1, 2, 3] Unpacking with * works with any object that is iterable and, since dictionaries return their keys when iterated through, you can easily create a list by using it within a list literal.
