The simplest way to get the first key in a dictionary in Python is to use the next() function with an iterator over the dictionary keys We need to have two points in mind: First dictionary in Python is designed to be a structure without order; Second it's difficult to point the first and last element of a Dictionary; Starting with Python 3.6 dict will keep the insert order of elements - check the experiment described in step 5.
Get First Key In Dictionary Python Update Finally, we select the first element of the sorted keys list using [0] and assign it to first_key Unlike a list object, the Python dict object isn't indexed, so you can't use the subscript operator [] to access the first key of a dictionary Below is an example of how you can use Python to get the first 3.
