Question

In this programming assignment, you will be writing a program that prints out several shapes via text. In this PA, you will be required to use functions and parameters. This is both to reduce redundancy and to make your code clean and well-structured. Name your program shaper.py Your program should have the capability to print out three different shapes: An hourglass, a plumbbob, or a house. Below is a table that shows examples of each of these shapes. hourglass plumbbob house ! A AAA AAAAA ΛΛΛΛΛΛΑ ΛΛΛΛΛΛΛΛΛ ΛΛΛΛΛΛΛΛΛΛΑ 1- 1 - 1 Notice that there are some common shapes within these larger shapes. All three utilize the I--------- line. All three utilize an upward-facing arrow. Both the hourglass and the plumbbob Have a downward-facing arrow. The characters in the arrows may differ, but the overall shapes are the same (other than the two directions). Input Values Your program should accept two values as input. The first should be a selection of the shape to print. It should check for hourglass plumbbob, and house. After asking for the shape, the program should ask for a single character, which should be used for the arrow(s). It should also ask for an integer, which will determine the number of |---------| rows to print out at one or more location(s) in the shape. If a supported shape is entered, the program should print out that shape utilizing the character for the arrow(s). If none of the three valid shapes are entered, the program should print out a message and then the program can end, or you can ask the user for the input repeatedly until a valid one is entered. You do not need to validate the single character or integer input. See the examples to determine what the prompts and message should be.

Hi. Please help me solve this in python using only while loops, if statements. Can't use for loops and lists.

Answer 1

def line(n):
    #Function to draw straight lines consisting of 1 | , 9 - and 1 | in order.
    #We need to print n lines.
    while(n>0):
        print("|" + 9*"-" + "|")
        n-=1

def up_arrow(c):
    n = 1
    #Drawing up arrow, in line number i, we have 2*i - 1 characters as specified by user.
    #Remaining (11 - 2*i - 1) characters are blank spaces, distributed on each side.
    while(n<=11):
        spaces = (11-n)//2
        current_line = " "*(spaces) + n*c + " "*spaces
        print(current_line)
        n+=2

def down_arrow(c):
    n = 11
    #Drawing down arrow, in line number i, we have 13 - (2*i) characters as specified by user.
    #Remaining (2*i - 2) characters are blank spaces, distributed on each side.
    while(n>0):
        spaces = (11-n)//2
        current_line = " "*(spaces) + n*c + " "*spaces
        print(current_line)
        n-=2

def main():
    print("Enter shape to display")
    shape = input()

    print("Enter arrow character")
    arrow_character = input()

    print("Enter row area height")
    height = int(input())

    if(shape == "hourglass"):
        line(height)
        down_arrow(arrow_character)
        up_arrow(arrow_character)
        line(height)
    
    elif(shape == "plumbbob"):
        up_arrow(arrow_character)
        line(height)
        down_arrow(arrow_character)

    elif(shape == "house"):
        up_arrow(arrow_character)
        line(height)
    
    else:
        print("Please enter a valid shape")

if __name__ == "__main__":
    main()

The code has been written as per requirements. The output looks like this-

Enter shape to display hourglass Enter arrow character ! Enter row area height 3 I. - . - ! !!! !!!!!!
