11.Python Dictionary

PYTHON DICTIONARY 
    A dictionary is a collection which is unordered, changeable and indexed. They are written with curly brackets, and they have keys and values. Keys are unique within a dictionary while values may not be. The values of a dictionary can be of any type, but the keys must be of an immutable data type such as strings, numbers, or tuples. Each key is separated from its value by a colon :, the items are separated by commas, and the whole thing is enclosed in curly braces.It is possible to access the dictionary by referring the key name inside square brackets and also by using get method. 


Program 
Fruits = { 
"name":"Apple", 
"color":"red", 
"taste":"good"} 
print(Fruits) 
print(Fruits[“name”]) 
print(Fruits.get(“ name “)) 
Output 
{'name': 'Apple', 'color': 'red', 'taste': 'good'} 
Apple 
Apple 
    We can add new items or change the value of existing items using an assignment operator. pop() method can be used to remove a particular item in a dictionary by. clear() method is used to remove All the items in the dictionary at once. In order to add or delete the dictionary,refer the program below 
Program
Fruits = { 
"name":"Apple", 
"color":"red", 
"taste":"good"} 
print(Fruits) 
print(Fruits["name"] ) 
Fruits["color"]="Yellow" 
print(Fruits) 
print(Fruits.pop('taste')) 
print(Fruits) 
Fruits.clear() 
print(Fruits) 
Output 
{'name': 'Apple', 'color': 'red', 'taste': 'good'} 
Apple 
{'name': 'Apple', 'color': 'Yellow', 'taste': 'good'}
