If you need to destructively iterate through a dictionary in Python, then .popitem() can do the trick for you: Python >>> likes = {"color": "blue", "fruit": "apple", "pet": "dog"} >>> while True: ... try: ... print(f"Dictionary length: {len(likes)}") ... item ...
1. Iterate a Dictionary in Python To iterate through a dictionary, we can use Python for loop. Let’s say, we want to print all elements in a dictionary, then we will use for loop as shown in the below example: Python 1 2 3 4 cubes = {1:1, 2:8, 3:21, 4:64, 5:125}...
Python Extend Dictionary Using For Loop For a more manual approach, you can use a for loop to iterate over the items in one dictionary and add them to another. Let’s see an example of an employee_data dictionary. # Create a dictionary called employee_data with two key-value pairs ...
Iterating Through a Nested Dictionary Using the for loops, we can iterate through each elements in a nested dictionary. Example 7: How to iterate through a Nested dictionary? people = {1: {'Name':'John','Age':'27','Sex':'Male'},2: {'Name':'Marie','Age':'22','Sex':'Female'...
Method 2 − Using iterables for values of the dictionary Example dict_inp = {'t':'u','t':'o','r':'i','a':'l','s':'p','o':'i','n':'t'} # Iterate over the string for value in dict_inp.values(): print(value, end='') Output oilpit Method 3 − Using keys as...
Iterate Through a Dictionary A dictionary is an ordered collection of items (starting from Python 3.7), therefore it maintains the order of its items. We can iterate through dictionary keys one by one using afor loop. country_capitals = {"United States":"Washington D.C.","Italy":"Rome"}...
