    Laboratory Exercise 01
    Topics
    1. Confidence with the IDE Visual Studio Code
    2. Print function
    3. Basic arithmetic operations
    4. Basic use of strings

    Exercises
    Part 1 – Basic operations to start with Python
    Delivery: For each of the following exercises, write a program in Python that responds to the requests
    indicated. Complete at least three exercises during the exercise, and the rest at home.

    01.1.1 Two numbers. Write a program that stores two integers in two constants defined in code,
    and then displays:

    A. The sum;
    B. The difference;
    C. The product;
    D. The average value;
    E. The distance (i.e. the absolute value of the difference);
    F. The maximum value (i.e. the greater of the two);
    G. The minimum value (i.e. the lesser of the two).

    Tip: Use the max() and min() functions defined in Python. They accept a comma-separated
    sequence of input values and return the maximum and minimum values of the sequence,
    respectively (for example, max(10, 5) returns 10). [P2.4]

    ##
    # Save two integers in two constants, and display the result of several
    calculations involving them.
    #
    NUM_1 = 20
    NUM_2 = 40
    # Alternatively, read the integers from the user.
    # NUM_1 = int(input("Enter an integer: "))
    # NUM_2 = int(input("Enter another integer: "))
    # Compute and display the sum, difference, product, average, distance,
    # minimum and maximum.
    print("Sum:", NUM_1 + NUM_2)
    print("Difference:", NUM_1 - NUM_2)
    print("Product:", NUM_1 * NUM_2)
    print("Average:", (NUM_1 + NUM_2) / 2)
    print("Distance:", abs(NUM_1 - NUM_2))
    print("Minimum:", min(NUM_1, NUM_2))
    print("Maximum:", max(NUM_1, NUM_2))

    01.1.2 Car’s use. You want to find out which fraction of your car’s use is for going to work, and which
    is for personal use. You know the one-way distance from your home to work. For a particular period,
    you recorded the beginning and ending kilometers on the odometer and the number of working
    days. Try to execute the follow code able of computing the fraction of car’s use for work and
    personal. Use the debug during the analysis.

    km_start = int(input("insert beginning kilometers: "))


    km_stop = int(input("insert ending kilometers: "))
    working_days = int(input("insert the number of working days: "))
    km_home_work = int(input("insert the home-work discance: "))

    km_total = km_stop - km_start


    km_work = working_days * (km_home_work *2)
    km_not_work = km_total - km_work

    km_work = 100 * (km_work/km_total)


    km_not_work = 100 * (km_not_work/km_total)

    print(10*"-")
    print("car used for work activities: ", km_work)
    print("car used for not work activities: ", km_not_work)

    01.1.3 Restaurant. Imagine that you and a number of friends go to a luxury restaurant, and when
    you ask for the bill, you want to split the total amount and the tip (15 percent) between all of you.
    Your program should print the total amount of the bill, the tip amount, the total cost (so the bill and
    the tip), and the amount each person has to pay. It should also print how much of what each person
    pays is for the bill and how much for the tip.

    01.1.4 Figures. Write a program that prints the sum of the first ten positive integers, 1 + 2 + … +
    10. [P1.2]

    01.1.5 Interests. Write a program that prints the balance of an account after the first, second, and
    third year. The account has an initial balance of $1,000 and earns 5 percent interest per year. [P1.4]

    01.1.6 Name in a box. Write a programs that displays your name inside a box on the screen, like:

    +---------+ +-------+
    ¦ WILLIAM ¦ ¦ W ¦
    +---------+ ¦ I ¦
    ¦ L ¦
    ¦ L ¦
    ¦ I ¦
    ¦ A ¦
    ¦ M ¦
    +-------+
    Do your best to approximate lines with characters such as “ | ” ,“ - ”, “ + ”, “ . ”, “ ¦ ”. [P1.5]

    01.1.7 Concatenation. A messaging application allows users to share text messages followed by their
    signatures. Write a program that asks the user to insert its username, the text message she/he
    wants to send and its signature, as three different strings. Then, the program should print to the
    output the username, followed by the column “:” character, followed by the whole message (text
    message and signature). This output should be in the same line.

    Finally, it should also print what is the length of the whole message (text and signature) the user
    sent.

    For example, if the user inserts “Daenerys” as username, “Hello, how are you?” as text message and
    “Best regards, Dany” as signature, the output should be:

    Daenerys: Hello, how are you? Best regards, Dany

    The length of the message is 38
