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
