Python: How to Return a dictionary keys as a list

Let's take a look at some of the possible ways in Python Programming to return a dictionary (dict) keys as a list.

Example 1: Using the dict.keys() method

locations = {'USA': 'New York', 'Japan': 'Tokyo', 'India': 'Mumbai'}

country_list = list(locations.keys())

print(country_list)

Output:

['USA', 'Japan', 'India']

Example 2: Using dictionary unpacking

locations = {'USA': 'New York', 'Japan': 'Tokyo', 'India': 'Mumbai'}

country_list = [*locations]

print(country_list)

Example 3: Using list comprehension

locations = {'USA': 'New York', 'Japan': 'Tokyo', 'India': 'Mumbai'}

country_list = [country for country in locations]

print(country_list)
