Answer:
This is the instance method inc_num_kids()
def inc_num_kids(self):
self.num_kids += 1
Explanation:
The first line is the definition of function inc_num_kids() which has a parameter self. self is basically an instance of class PersonInfo
self.num_kids += 1 this statement incremented the data member num_kids by 1. This means that the instance method inc_num_kids, using instance self, increments the value of num_kids data member by 1.
The complete program is as following:
class PersonInfo: #class name PersonInfo
def __init__(self): #constructor of the class
self.num_kids = 0 # data member num_kids
def inc_num_kids(self): # method inc_num_kids
self.num_kids += 1 #increments num_kids by 1
person1 = PersonInfo() #creates object person of class PersonInfo
print('Kids:', person1.num_kids) # prints num_kids value before increment
person1.inc_num_kids() #calls inc_num_kids method to increment num_kids
print('New baby, kids now:', person1.num_kids) #prints the value of num_kids after increment by inc_num_kids method
The person1 object first access the initial value of num_kids initialized by the constructor. So the first value of num_kids is 0. self.num_kids = 0 This statement assigns the value 0 to num_kids data member. Next the method inc_num_kids() using the object person1. Now when this method is called the value of data member num_kids is incremented to 1.
So previously the value was 0 which now increments by 1 and becomes 1. Last print statement displays this new value which is incremented by the inc_num_kids() method.
Hence the output is:
Kids: 0
New baby, kids now: 1
The program along with its output is attached.

Explanation:
The following code is written in Java and creates the BankAccount class with all of the requested methods, including the constructor, getter and setter methods, withdraw methods, and even the transferToSavings method. A preview can be seen in the attached image below.
class BankAccount {
private String customerName;
private double savingsBalance, checkingsBalance;
public BankAccount(String newName, double amt1, double amt2) {
this.customerName = newName;
this.checkingsBalance = amt1;
this.savingsBalance = amt2;
}
public String getCustomerName() {
return customerName;
}
public void setCustomerName(String customerName) {
this.customerName = customerName;
}
public double getSavingsBalance() {
return savingsBalance;
}
public void setSavingsBalance(double savingsBalance) {
this.savingsBalance = savingsBalance;
}
public double getCheckingsBalance() {
return checkingsBalance;
}
public void setCheckingsBalance(double checkingsBalance) {
this.checkingsBalance = checkingsBalance;
}
public void depositChecking(double amt) {
if (amt > 0) {
this.checkingsBalance += amt;
}
}
public void depositSavings(double amt) {
if (amt > 0) {
this.savingsBalance += amt;
}
}
public void withdrawChecking(double amt) {
if (amt > 0) {
this.checkingsBalance -= amt;
}
}
public void withdrawSavings(double amt) {
if (amt > 0) {
this.savingsBalance -= amt;
}
}
public void transferToSavings(double amt) {
if (amt > 0 ) {
this.checkingsBalance -= amt;
this.savingsBalance += amt;
}
}
}
