# {'course': 'python', 'fee': 4000, 'duration': '45 days'} 4. Convert List to Dictionary Using For Loop You can also convert the list to dict using for loop. For that we need to create an empty dictionary and then iterate over the list, for each iteration, the key-value pair ...
You can directly iterate over the keys of a Python dictionary using a for loop and access values with dict_object[key]. You can iterate through a Python dictionary in different ways using the dictionary methods .keys(), .values(), and .items(). You should use .items() to access key-...
Convert a dictionary to a list of tuples using a for loop We can convert apython dictionaryto a list of tuples using a for loop by accessing the keys and values of the dictionary one by one. First, we will create tuples using keys and values and then we will append them to a list...
Set the value of a dictionary item also using the key. d['i'] += 1 d['i'] [$[Get Code]]2 📑 Unpack DictionaryEach key of a dictionary is accessed when d is used as an iterator in a for loop. for k in d: print(k) [$[Get Code]]i x e ...
To access element of a nested dictionary, we use indexing[]syntax in Python. Example 2: Access the elements using the [] syntax people = {1: {'name':'John','age':'27','sex':'Male'},2: {'name':'Marie','age':'22','sex':'Female'}}print(people[1]['name'])print(people[1...
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"}# print dictionary keys one...
