Extract Dictionary Values as a List in Python

Here are 3 approaches to extract dictionary values as a list in Python:

(1) Using a list() function:

my_list = list(my_dict.values())

(2) Using a List Comprehension:

my_list = [i for i in my_dict.values()]

(3) Using a For Loop:

my_list = []

for i in my_dict.values():
    my_list.append(i)

Examples

Example 1: Use a list() function to extract dictionary values as a list

To start with a simple example, create a dictionary as follows:

my_dict = {"A": 300, "B": 150, "C": 500, "D": 850, "E": 400}

print(my_dict)
print(type(my_dict))

You’ll then get this dictionary:

{'A': 300, 'B': 150, 'C': 500, 'D': 850, 'E': 400}
<class 'dict'>

Note that “print(type(my_dict))” was added at the bottom of the script to demonstrate that you got a dictionary.

Next, use a list() function to extract the dictionary values as a list:

my_dict = {"A": 300, "B": 150, "C": 500, "D": 850, "E": 400}

my_list = list(my_dict.values())

print(my_list)
print(type(my_list))

As you can see, the dictionary values were extracted as a list:

[300, 150, 500, 850, 400]
<class 'list'>

Example 2: Use a list comprehension to extract dictionary values

Now, extract the dictionary values as a list using a List Comprehension:

my_dict = {"A": 300, "B": 150, "C": 500, "D": 850, "E": 400}

my_list = [i for i in my_dict.values()]

print(my_list)
print(type(my_list))

You’ll get the same list as in the previous example:

[300, 150, 500, 850, 400]
<class 'list'>

Example 3: Use a for loop to extract dictionary values

Finally, use a For Loop to extract the values as a list:

my_dict = {"A": 300, "B": 150, "C": 500, "D": 850, "E": 400}

my_list = []

for i in my_dict.values():
    my_list.append(i)

print(my_list)
print(type(my_list))

As before, you’ll get the same list:

[300, 150, 500, 850, 400]
<class 'list'>

Extract Dictionary Values as a List of Lists

What if you’d like to extract the dictionary values as a list of lists?

For example, suppose that you have the following dictionary:

my_dict = {"A": [300, 305, 310], "B": [150, 155, 160], "C": [500, 505, 510]}

print(my_dict)
print(type(my_dict))

The resulted dictionary:

{'A': [300, 305, 310], 'B': [150, 155, 160], 'C': [500, 505, 510]}
<class 'dict'>

To extract the dictionary values as a list of lists:

my_dict = {"A": [300, 305, 310], "B": [150, 155, 160], "C": [500, 505, 510]}

my_list = list(my_dict.values())

print(my_list)
print(type(my_list))

You’ll now get a list of lists:

[[300, 305, 310], [150, 155, 160], [500, 505, 510]]
<class 'list'>
