Python program to get the keys of a dictionary

A dictionary contains the pair of the keys & values (represents key : value), a dictionary is created by providing the elements within the curly braces ({}), separated by the commas.

Here, we are going to access and print the all keys of a dictionary, there are some of the ways to get the keys of a dictionary.

Using loop through a dictionary
Using the keys() method

1) Get the keys of a dictionary by looping through a dictionary

When we loop through a dictionary, it returns the keys only. In this way, we can get and print the all keys of a dictionary.

Syntax:

for key in dictionary_name: print(key)

Program:

# Python program to get the keys of a dictionary # by looping through a dictionary # creating the dictionary dict_a = {'id' : 101, 'name' : 'Amit', 'age': 21} # printing the dictionaries print("Dictionary \'dict_a\' is...") print(dict_a) # looping through a dictionary # and, printing the keys print("Keys of the Dictionary \'dict_a\'...") for x in dict_a: print(x)

Output:

Dictionary 'dict_a' is... {'name': 'Amit', 'id': 101, 'age': 21} Keys of the Dictionary 'dict_a'... name id age

2) Get the keys of a dictionary by using the keys() method

The keys() method is a built-in method in Python and it returns a view object containing the keys of the dictionary as a list.

Syntax:

dictionary_name.keys()

Program:

# Python program to get the keys of a dictionary # by using the keys() method # creating the dictionary dict_a = {'id' : 101, 'name' : 'Amit', 'age': 21} # printing the dictionaries print("Dictionary \'dict_a\' is...") print(dict_a) # getting the keys of a dictionary # using keys() method and, printing the keys print("Keys of the Dictionary \'dict_a\'...") print(dict_a.keys())

Output:

Dictionary 'dict_a' is... {'name': 'Amit', 'id': 101, 'age': 21} Keys of the Dictionary 'dict_a'... dict_keys(['name', 'id', 'age'])
