Python Get the first key in a dictionary

Author:JIYIK Last Updated:2025/05/06 Views:

This tutorial explains how to get the first key in a Python dictionary. The so-called first key refers to the key stored in the first index of the dictionary.

In Python 3.7 and above, when dictionaries are ordered, we can get the first key iter()by first converting the dictionary into an iterable object using the get_key function and then nextgetting its first index key using the get_key function.

The second way is list()to convert the dictionary into a list using the function and then 0get the key at index .

A third approach is to use fora loop to get the first key in the dictionary.


Use iter()the function to get the first key in the dictionary

The code example given below shows how we can get the first key in a Python dictionary using the iter()and functions.next()

my_dict = {"London": 2, "New York": 1, "Lahore": 6, "Tokyo": 11}

print(next(iter(my_dict)))

Output:

London

Use list()the function to get the first key in the dictionary

We can also convert the type to a list using list()the function first dict, and then 0get the first key at index .

my_dict = {"London": 2, "New York": 1, "Lahore": 6, "Tokyo": 11}

print(list(my_dict.keys())[0])

Output:

London

Use forloop to get the first key in the dictionary

Another way is to use fora loop to get the first key in the dictionary. After we get the first key of the dictionary, we can break the loop.

Code example:

my_dict = {"London": 2, "New York": 1, "Lahore": 6, "Tokyo": 11}

for key, value in my_dict.items():
    print(key)
    break

Output:

London
