Dictionaries are Python’s most powerful data collection. Dictionaries allow us to do fast database-like operations in Python. Dictionaries have different names in different languages. Associative Arrays - Perl / Php. Properties or Map or HashMap - Java. Property Bag - C# / .Net. http://en.wikipedia.org/wiki/Associative_array. Dictionaries.

Like with English dictionary we search any word for meaning associated with it, similarly in Python we search for “key” to get its associated value rather than searching for an index. Creating a Dictionary. Syntax to create dictionary: dictionary_name = {key1:value,key2:value,....} Example. > emp = {"empno":1,"name":"Shahrukh","fee":1500000} Here
The dictionary (also known as a hashtable or hashmap in other languages) is one of the most powerful data structures Python has available to use. Luckily, since it’s built in to the Python language, we don’t have to implement it ourselves. We will also be learning about tuples.
INTRODUCTION. Dictionary are mutable, unordered collection with elements in the form of a key:value pairs that associate keys to values. Rather than index associated with lists, tuples and strings, a dictionary has key associated with values.
In this Python Tutorial, we learned how to initialize a Dictionary in Python, how to iterate through the key:value pairs of the dictionary, how to add a new key:value pair to the dictionary and many other operations that could be performed on a Python Dictionary.
