How does object-oriented programming work in Python?

Answers

Answer 1
Answer: So basically you have a class, and within that class you have methods and instance variables; very much like how object oriented programming works in other languages. However, the main difference is that the class constructor in Python is defined right within the class object and is denoted by the method name, "__init__" and requires a parameter of "self". 
Ex:
class Py:
    def __init__(self):
          constructor code...
The __init__ method is what is called first when an object of the class is instantiated. The way you instantiate an object is by the following:
object_name = Py()

If you wanted to make your class more useful, you could add more parameters to your __init__ constructor, so when an object is created you can pass arguments to that object:
class Py:
    def __init__(self, name, age):
         self.name = name
         self.age = age
         print "Your name is %s and you are %d years old" % (name, age)
def main():
     Bob = Py("Bob", 23)
if __name__ == "__main__":
     main()

This code would give you: Your name is Bob and you are 23 years old

for the employee class program in the unit 3 finishing the employee class program tutorial, what if we need to update the display menu and selections to add in a way to change the id of an employee? what code segments would need to be added to the display menu() method and the command while loop respectively to implement this?

Answers

To update the display menu and selections in the Employee class program tutorial to include the option to change an employee's ID, you would need to add code segments to the `display_menu()` method and the command `while` loop.

Here's a possible implementation:

```python

class Employee:

   def __init__(self, name, id):

       self.name = name

       self.id = id

   def display_menu(self):

       print("1. Change ID")

       print("2. Display Employee Details")

       print("3. Quit")

   def change_id(self):

       new_id = input("Enter new ID: ")

       self.id = new_id

       print("Employee ID changed successfully.")

   def run(self):

       choice = 0

       while choice != 3:

           self.display_menu()

           choice = int(input("Enter your choice: "))

           if choice == 1:

               self.change_id()

           elif choice == 2:

               self.display_details()

           elif choice == 3:

               print("Quitting...")

           else:

               print("Invalid choice. Try again.")

   def display_details(self):

       print("Employee Name:", self.name)

       print("Employee ID:", self.id)

```

In the updated code, the `display_menu()` method now includes the option "1. Change ID" to indicate the ability to change the employee's ID.

Inside the `run()` method, the `choice` variable is used to track the user's input. If the choice is 1, the `change_id()` method is called, which prompts the user to enter a new ID and updates the `id` attribute of the employee object accordingly.

With these additions, the updated Employee class program allows users to select the option to change the ID of an employee from the menu and executes the necessary code to facilitate the ID change.

To use the AutoCalculate area, select the range of cells containing the numbers for a calculation you want to verify and then press and hold or double-click the AutoCalculate area to display the Customize Status Bar shortcut menu.A) True
B) False

Answers

Answer:

The answer to this question is option "B".

Explanation:

The auto calculate is a part of the excel. It provides the facility to understand things more easily. In the excel we use many functions like insert pie charts, use formulas or add formulas, add column or row, merge column or row, etc. When we calculate the area of any number this process can be done in two way that can be given as:

1) we select all number and go to ribbon in the ribbon there is a formula tab in this we can calculate the area.

2) After selecting all number right-click on the mouse when we click there are many options shown in this option there is the option of calculating the area.  

To calculate the area we must follow these options. So the answer to this question is false.

Which of the following expressions will produce a valid random integer between the int values m and n inclusive, where m < n?

Answers

Answer:

The solution code is written in Python:

m = 1

n = 5

d = random.randint(m, n)

Explanation:

To get a random integer between m and n inclusive, we can make use of Python randint method. It will take two parameters, m and n. By giving two integers as an input (e.g. 1 and 5) to randint, it will generate a random integer between 1 to 5 inclusive.
