Python Program to Print all key names in a dictionary, one by one

In the following example of Python program You can use a for loop to iterate over the keys of a dictionary and print them one by one :

Program :

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

for key in my_dict:
    print(key)

Output :

name
age
city

Alternatively, you can use the `keys()` method to get a list of all the keys in the dictionary and then iterate over the list :

Program :

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

for key in my_dict.keys():
    print(key)

Output :

name
age
city

Both of these programs produce the same output.
