Let’s look at some crucial features that are very useful when experimenting with dictionaries in Python.

Python Dictionary Methods:

Functions	Description
clear()	Eliminates everything from the dictionary
copy()	Returns a shallow copy of the dictionary
fromkeys()	A dictionary is formed using the provided sequence.
get()	Returns the value for the given key
items()	Return the list with all dictionary keys with values
keys()	Returns a view object that shows a list of all the dictionary’s keys in the order they were added.
pop()	Returns the element with the specified key and removes it.
popitem()	Returns and removes the key-value pair from the dictionary
setdefault()	Returns the value of a key if the key is in the dictionary else inserts the key with a value to the dictionary
update()	Updates the dictionary with the elements from another dictionary
values()	Returns a list of all the values available in a given dictionary

Example:

Dict={"name": "Coderzpy", 
    "type": "Educational", 
    "price": "free", 
    "work-style": "remote"}
print(len(Dict))
print(Dict.values())
print(Dict.items())
print(Dict.keys())
print(Dict.__contains__('name'))
Dict.clear()
print(Dict)

Output:

4
dict_values(['Coderzpy', 'Educational', 'free', 'remote'])
dict_items([('name', 'Coderzpy'), ('type', 'Educational'), ('price', 'free'), ('work-style', 'remote')])
dict_keys(['name', 'type', 'price', 'work-style'])
True
{}
