class me:
def __init__(self,name,age,gender,height,mother):
self.name = name

self.gender = gender
self.height = height
self.mother = mother

Answer 1

Answer

class Person:
def __init__(self, age):
self.age = int(age)

@property
def isAdult(self):
if self.age > 18:

return True
else:

return

False

Answer 2

It's not about the classes themselves, but the class instances. The mother you're trying to give to me's constructor doesn't exist yet. Try removing mother's initialization from the __init__, and make a separate function to initialize it.

Answer 3

Hey, this is pretty late, but since I was bored, I modified your code to make it work. It has a restriction: You cannot create a child before creating a mother (just like in real life!).

class mother:
def __init__(self, husband, name, age):
self.husband = husband
self.name = name
self.age = age

def SetChild(self, child):
self.child = child

class me:
def __init__(self,name,age,gender,height,mother):
self.name = name
self.age = age
self.gender = gender
self.height = height
self.mother = mother
self.mother.SetChild(self)

Hem = mother("Ban","Hem",42)
Jan = me("Jan",23,"male",6,Hem)
print (Jan.mother.name)

Answer 4

You're giving Hem as a parameter to me's constructor, even though Hem is defined the line after.

class Student {
Public:
int age;
public:
Student(int a) {
setAge(a);
}
void setAge(int a) {
age = a;
}
Int getAge() {
Return age;
}
};

Answer 6

class Student {
private:
int age;
public:
Student(int a) {
setAge(a);
}
void setAge(int a) {
age = a;
}
getAge() {
age;
}
};

Answer 7

yep,.. in such situation why can't it call the 2nd class to get details of it to the 1st class
is there any way to do it?...

Answer 18

Fill in the blanks to make the egg attribute strongly private and access it from outside of the class.
class Test:

egg = 7

t = Test()
print(t.

Test

)

Answer 19

Fill in the blanks to evaluate the R-squared on the testing data:

model.score(X_test, Y_test)

Answer 20

Complete the code to train a multivariate linear regression model to predict the MEDV based on features RM, LSTAT, and CRIM (per capita crime rate by town):

X3 = boston[['RM', 'LSTAT', ‘CRIM’]]
Y = boston['MEDV']
X3_train, X3_test, Y_train, Y_test = train_test_split
(X3, Y, test_size= 0.3, random_state=1)
model3 = LinearRegression() model3.fit(X3_train, Y_train)
