Please write the codes exactly as you would have typed it in Python (or in Notepad); simple, plain and straightforward!. Thank you!.

This is the code for Lab 3.1

To start, you can define a main function that will handle the program processing and output. Within this function, you can prompt the user to choose a mathematical function from the list of options, and then use an if-elif-else statement to call the corresponding function based on the user's choice.

For example:

def main(): print("Choose a mathematical function:") print("1. Calculate the area of a circle given the diameter") print("2. Calculate the MPG for a vehicle") print("3. Calculate the total number of hours worked in a week") print("4. [User-defined function 1]") print("5. [User-defined function 2]")

choice = int(input())

if choice == 1: calculate_circle_area() elif choice == 2: calculate_mpg() elif choice == 3: calculate_total_hours_worked() elif choice == 4: [user-defined function 1] elif choice == 5: [user-defined function 2] else: print("Invalid choice. Please try again.")

You can then define the functions for each of the mathematical calculations, such as calculate_circle_area, calculate_mpg, and calculate_total_hours_worked. These functions should prompt the user for the necessary input, perform the calculation, and return the result to the main function.

Finally,

IT 280 - Lab \#6: Package Creation Lab Instructions Preconditions: - Python is installed. - Reading completed. To submit this Program - Submit the package and a Python program that uses the package - as an extension of the List Manipulation Lab (Lab 3.1). Package - Create a package that has three functions: o sortLow (list) - sorts from a to z. o sorthigh (list) - sorts from z to a. o removeDup (list) - removes duplicates from the list. Program Inputs: - As an extension to Lab 3.1, follow the instructions for that lab, with the following modification that rather than using a local program function, you use a function in the package for sorting and removing the duplicate values. Program Processing (same as Lab 3.1): - If the list is empty, return a message that this list is empty. An empty list would be created if when a list is inputted, only a carriage return CR> is entered. Using the + operator, print the specified output. - If this list is non-empty, o The list is sent to a function to be sorted. o The list is sent to a function to remove duplicates. Program Output (same as Lab 3.1): - The sorted list will be printed to the screen
