encapsulation is a method of wrapping data and functions into a single entity.Acts as a protective layer which means internal representation of an object is generally hidden from outside of the object's definition.
class Employee:
def __init__(self,name,salary):
#private
self.name = name
#private member
# not accessible outside of a class
self.__salary = salary
def show(self):
print("Name is", self.name, "and salary is", self.__salary)
emp = Employee("Jessa", 10000)
emp.show()
# access salary from outside of a class
print(emp.__salary)
output
Name is Jessa and salary is 10000
