How to extract all values from a dictionary in Python

In this Python tutorial, we will understand how to get all values from a dictionary in Python.

We can get all values from a dictionary in Python using the following 5 methods.

1. Using dict.values()
2. Using * and dict.values()
3. Using for loop & append()
4. Using the map() function
5. Using list comprehension & dict.values()

Get all values from a dictionary Python

Here we will illustrate multiple methods to get all values from a Python Dictionary. And for this, we will start with the dict.values() method.

Method 1: Using dict.values()

The dict.values() in Python is a Dictionary method that fetched all the values from the dictionary and returns a dict_values object. This object contains all the values of a dictionary.

However, we can easily convert this dict_values object into a list using the list() constructor in Python.

Here is an example of this approach in Python.

# Defining a dictionary
Countries = {
    6:'Canada',
    2:'United Kingdom',
    1:'United States',
    9:'Australia',
    7:'China'
} 

# Fetching all dictionary values
country_names = list(Countries.values())

# Printing all dictionary values
print(country_names)

In the example, we are fetching all the values from the Countries dictionary using the dict.values() method. After this, convert the result of the dict.values() method into a list using list() function.

The result of the Python program is shown below.

['Canada', 'United Kingdom', 'United States', 'Australia', 'China']

Method 2: Using * and dict.values()

Alternatively, we can also use the * operator with the dict.values() method to fetch all the values from a dictionary in Python.

Here is an example of this execution in python.

# Defining a dictionary in Python
user_data = {
    'Name': 'Alex',
    'Age': 32,
    'City': 'Chicago',
    'Country': 'United States',
    'Technical Skills': ['SQL', 'Java']
}

# Fetching all dictionary values
user_values = [*user_data.values()]

# Printing all dictionary values
print(user_values)

In this example, we utilized the * operator with dict.values() to fetch all the values from the user_data dictionary.

['Alex', 32, 'Chicago', 'United States', ['SQL', 'Java']]

Method 3: Using for loop & append()

In this method, we will use the for loop to iterate over each dictionary value using dict.values(). And then we use the append() method to store the value in a Python List.

The execution related to this approach is given in the Python code below.

# Defining a dictionary
Countries = {
    6:'Canada',
    2:'United Kingdom',
    1:'United States',
    9:'Australia',
    7:'China'
} 

# Defining empty dictionary
country_names = []

# Fetching all dictionary values
for value in Countries.values():
    country_names.append(value)
    
# Printing all dictionary values
print(country_names)

• In this example, we used for loop over the Countries.values() and fetch each dictionary value.
• After this, we used the append() method on the country_names list to store every dictionary value in it.

The result of the Python program is given below.

['Canada', 'United Kingdom', 'United States', 'Australia', 'China']

Method 4: Using list comprehension & dict.values()

• In this method, we used the same dict.values() method to fetch all the dictionary values as dict_values object.
• Then we used the concept of list comprehension to generate a new list using the result of dict.values().

# Defining a dictionary in Python
countries_hdi = {
    'Canada': 0.937,
    'United Kingdom': 0.935,
    'United States': 0.921,
}

# Fetching all dictionary values
hdi_values = [value for value in countries_hdi.values()]

# Printing all dictionary values
print(hdi_values)

Here we used the countries_hdi.values() method to get all list of values from countries_hdi dictionary. And we also used list comprehension using the countries_hdi.values() method.

This will result in forming another list named hdi_values containing all the values from the countries_hdi dictionary values. Once we print the hdi_values list, we will get the following result.

[0.937, 0.935, 0.921]

Method 5: Using the map() function

Another way to get all values from a Python Dictionary is by using the map() function with dict.get() method.

The dict.get() function in Python allows fetching the value of a particular key given in a dictionary. On the other hand, the map() function allows to execution of a function for each value given in an iterable.

So, in this approach, we will fetch all the keys from a dictionary and use each key name with map() and dict.get() function. This allows fetching each value corresponding to a key in Dictionary.

An example of this approach is shown in the code below.

# Defining a dictionary in Python
user_data = {
    'Name': 'Alex',
    'Age': 32,
    'City': 'Chicago',
    'Country': 'United States',
    'Technical Skills': ['SQL', 'Java']
}

# Fetching all dictionary values
keys = list(user_data.keys())
user_values = list(map(user_data.get, keys))

# Printing all dictionary values
print(user_values)

Once we execute the above Python program, we will get the following result.
