== ---> object.

__eq__(self,other)
!= ---> object.__ne__(self,other)

Overloading > and <= operators for Student class objects:

1) class Student:
2) def __init__(self,name,marks):
3) self.name=name
4) self.marks=marks
5) def __gt__(self,other):
6) return self.marks>other.marks
7) def __le__(self,other):
8) return self.marks<=other.marks
9)
10)
11) print("10>20 =",10>20)
12) s1=Student("Durga",100)
13) s2=Student("Ravi",200)
14) print("s1>s2=",s1>s2)
15) print("s1<s2=",s1<s2)
16) print("s1<=s2=",s1<=s2)
17) print("s1>=s2=",s1>=s2)

Output:
10>20 = False
s1>s2= False
s1<s2= True
s1<=s2= True
s1>=s2= False

Program to overload multiplication operator to work on Employee objects:

1) class Employee:
2) def __init__(self,name,salary):
3) self.name=name
4) self.salary=salary
5) def __mul__(self,other):
6) return self.salary*other.days
7)
8) class TimeSheet:
9) def __init__(self,name,days):
10) self.name=name
11) self.days=days
12)
13) e=Employee('Durga',500)
14) t=TimeSheet('Durga',25)
15) print('This Month Salary:',e*t)

Output: This Month Salary: 12500
