hash()

A hash is an fixed sized integer that identifies a particular value.
hash(object) : Returns hash value of the input object ( if available )
Hashable and Immutable
hash() value is available for immutable objects ( what is immutable and mutable object ?), but all Hashable are not immutable.

print(hash(300))        # 300 
print(hash(300.56))     #1291272085159674156
print(hash('plus2net')) #-4778224534751702784
hash value of tuple
my_tuple=('Alex','Ronald','John')
print(hash(my_tuple))      # 7654376616106661247
hash value of list
my_list=['Alex','Ronald','John']
print(hash(my_list)) # Error
Above code will generate error
 TypeError: unhashable type: 'list'
hash() value of user defined object
class student_kit():
    college_name='ABC College'  #class attributes

     #instance attributes
    def __init__(self,name,section):
        self.name= name
        self.section=section
        self.height=5  #instance attribute

Alex=student_kit('Alex','A')  # object declaration

print(hash(Alex))  # -9223371866271725652
