How to use Dictionary in Python | Python Beginners | தமிழ்

In this Video, you'll learn everything about Python dictionaries. How they are created, accessing, adding, removing elements from them and various built-in methods. Python dictionary is an unordered collection of items. Each item of a dictionary has a key/value pair. Dictionaries are optimized to retrieve values when the key is known. Python Dictionary: 1. Creating Python Dictionary. 2. Accessing Elements from Dictionary. 3. Changing and Adding Dictionary elements. 4. Removing elements from Dictionary. 5. Python Dictionary Methods. 6. Dictionary Membership Test. 7. Iterating Through a Dictionary. 8. Dictionary Built-in Functions. Python Dictionary Methods: Method Description clear() Removes all items from the dictionary. copy() Returns a shallow copy of the dictionary. fromkeys(seq[, v]) Returns a new dictionary with keys from seq and value equal to v (defaults to None). get(key[,d]) Returns the value of the key. If the key does not exist, returns d (defaults to None). items() Return a new object of the dictionary's items in (key, value) format. keys() Returns a new object of the dictionary's keys. pop(key[,d]) Removes the item with the key and returns its value or d if key is not found. If d is not provided and the key is not found, it raises KeyError. popitem() Removes and returns an arbitrary item (key, value). Raises KeyError if the dictionary is empty. setdefault(key[,d]) Returns the corresponding value if the key is in the dictionary. If not, inserts the key with a value of d and returns d (defaults to None). update([other]) Updates the dictionary with the key/value pairs from other, overwriting existing keys. values() Returns a new object of the dictionary's values
