Operations in Dictionary in Python There are various operations in a dictionary, and in this section we will learn about some of the most basic and most frequently used operations such as iterating through a dictionary, adding new elements, updating already existing elements, removing some specifi...
Iterating over a dictionary using for loop As we iterate through lists or tuples using for loops in python, we can also iterate through apython dictionaryusing a for loop. When we try to iterate over a dictionary using for loop,it implicitly calls__iter__()method. The__iter__()method...
Iterating through dictionaries If you need to iterate through a dictionary to inspect all of its keys or values, there are a few different ways to do it. The most common is to use a for loop on the dictionary—e.g., for item in the_dict. This yields up the keys in the dictionary...
Python dictionary sorting Starting from Python 3.7, dictionaries in CPython (the most common implementation of Python) maintain insertion order. This means the order in which you add key-value pairs to the dictionary is preserved when iterating over it or accessing elements. ...
We can iterate through a dictionary using a for-loop and access the individual keys and their corresponding values. Let us see this with an example. person = {"name": "Jessa", "country": "USA", "telephone": 1178} # Iterating the dictionary using for-loop print('key', ':', 'value...

Regardless of their parent dictionary, the above iteration outputs all the child values from the nested dictionary. Modifying Dictionary Items Since a dictionary is mutable, you can modify its content as you like while iterating through it. For instance, you can swapvaluesforkeysand insert the ou...
