How to make a list of python dictionary keys

Make a list from a Python dictionary's keys w/ example: dict_keys([1,2,3]) -> [1,2,3]

Creating a List of Python Dictionary Keys

Python dictionaries are incredibly powerful data structures for storing and manipulating data. One of the most common operations on dictionaries is to create a list of all the keys associated with a particular dictionary. In this tutorial, we'll take a look at how to do that.

The most straightforward way to create a list of keys from a Python dictionary is to use the

dict.keys()

method. This method returns a list of all the keys associated with the dictionary. For example, let's say we have a dictionary called my_dict that looks like this:


my_dict = {
  "name": "John",
  "age": 30,
  "city": "New York"
}

We can use the

dict.keys()

method to get a list of the keys associated with this dictionary:


key_list = my_dict.keys()

# Output: ["name", "age", "city"]

The

dict.keys()

method returns an iterable view object, which can be converted into a list with the list() function if needed. For example:


key_list = list(my_dict.keys())

# Output: ["name", "age", "city"]

Another way to create a list of keys from a Python dictionary is to use a list comprehension. For example, we can use the following list comprehension to create a list of keys:


key_list = [key for key in my_dict]

# Output: ["name", "age", "city"]

In this tutorial, we looked at two different ways to create a list of keys from a Python dictionary. Using the

dict.keys()

method is the simplest and most straightforward approach, while using a list comprehension provides a more versatile and powerful solution.
