Tutorial#12 Dictionary in Python Part01 #python #pythonprogramming #python3

Dictionary in Python is a collection of keys values pairs(internally uses hashing) which is ordered*, changeable and do not allow duplicates.
Key-Value is provided in the dictionary to make it more optimized. 
Values in a dictionary can be of any data type and can be duplicated, whereas keys can’t be repeated and must be immutable. 
Dictionary is heavily optimized for memory overhead and lookup speed efficiency.


*As of Python version 3.7, dictionaries are ordered. In Python 3.6 and earlier, dictionaries are unordered.
