Write a class called Person that has two private data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method.

Does the code have a get_age method?

def std_dev(list) :
sum = 0
for p in list:
sum += p.age
avg = sum/len(list)
# variance is average of squares of difference of each number and their average
square_sum = 0;
for p in list:
square_sum += (p.age-avg)**2
var = square_sum/len(list)
# standard deviation is root of variance
std = var**0.5
return std
class Person:
def
_init_(self, name, age):
self.name = name
self.age = age
pl = Person("John", 36)
p2 = Person("Rick", 49)
p3 = Person("Kylie", 28)
person_list = [p1,p2,p3]
answer =
std_dev(person_list)
print("standard daviation is : ", answer)
