Python Tutorial for Beginners 16 - Python Dictionary

In this video I am going to show What are Dictionaries and How to use Dictionaries in python. So What are Dictionaries in python?
dictionary in python is an associative list or a map.
We can think if dictionary as a list of pairs, where the first element of the pair, the key, is used to retrieve the second element, the value.Hence we map a key to a value.Dictionaries are Python’s most powerful data collection. Dictionaries allow us to do fast database-like operations in Python.Dictionaries are like Lists except that they use keys instead of Index to lookup values.

The list of all functions which can be use with Python Dictionaries :
['__class__', '__contains__', '__delattr__', '__delitem__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'clear', 'copy', 'fromkeys', 'get', 'items', 'keys', 'pop', 'popitem', 'setdefault', 'update', 'values']
