Method 3: Using dict() Constructor Thedict()constructor allows creating a new dictionary and adding a value to an existing one. When using the second approach, the method creates a copy of a dictionary and appends an element to it. The syntax is: new_dictionary = dict(old_dictionary, key...

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-...
First, the copies of dict1 and dict2 have been attached to a list using square brackets. Then the operation of addition took place. Finally, my_list matching the previous example has been obtained. Well done! At this point, I guess we are familiar with the copy-append method of adding ...

Specified sort keys to sort a dictionary by value, key, or nested attribute Used dictionary comprehensions and the dict() constructor to rebuild your dictionaries Considered whether a sorted dictionary is the right data structure for your key-value data You’re now ready to not only sort dictiona...
The Python language is specific about what can be used as a key in a dictionary. In a Python dictionary, all keys must be hashable. If you try to use an unhashable key type when adding a key to a dictionary, you’ll encounter the “TypeError: unhashable type: ‘dict’” error. Find...
