Question

USING PYTHON 3.

For this question, you will build three helper functions and one main function. All four functions must work together to draw the letter ‘H. Every line of code written should be inside of a function.

Here are the function specifications:

1) Helper function (given):

def draw_edges(symbol, width):

print(symbol + " "*(width-2) + symbol)

2) Helper function:

draw_H(symbol, width, height):

This function will draw an "H" symbol, given the symbol, width, and height. This function must call the draw_edges function at least once.

3) Helper function:

get_width()

This function will prompt the user for an odd integer 3 or greater and error check the input to ensure it is valid.

4) Main function:

draw_letter(symbol)

The main function must call get_width to obtain the width, calculate letter height (width+2), and then must call draw_H appropriately to draw the ‘H’ with the information given.

What is the line of code that will execute this task given these functions?

Answer 1

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

Note: Please maintain proper code spacing (indentation), just copy the code part and paste it in your compiler/IDE directly, no modifications required.

#code

#prints symbol followed by width-2 spaces and then symbol again
def draw_edges(symbol, width):
    print(symbol + " "*(width-2) + symbol)

#This function will draw an "H" symbol, given the symbol, width, and height
def draw_H(symbol, width, height):
    #looping for height number of times
    for i in range(height):
        #if this is middle row, printing width number of symbols
        if i==height//2:
            print(symbol*width)
        else:
            #otherwise calling draw_edges()
            draw_edges(symbol,width)

#This function will prompt the user for an odd integer 3 or greater and error check the
# input to ensure it is valid.
def get_width():
    n=0
    #looping as long as n is less than 3
    while n<3:
        #asking and reading n
        try:
            n=int(input("Enter width (3 or above): "))
        except:
            #in case of exception, setting value of n to 0
            n=0
        #after a loop, if n is less than 3, printing error, asking again
        if n < 3:
            print('Invalid width, please try again!')
    #finally returning n if it is valid
    return n

#this will draw the letter H with given symbol
def draw_letter(symbol):
    #reading width, calculating height
    width=get_width()
    height=width+2
    #drawing H by calling draw_H()
    draw_H(symbol,width,height)


#the below line of code will draw letter H with symbol 'H' after reading width from user
draw_letter('H')

#output

Enter width (3 or above): -2 Invalid width, please try again! Enter width (3 or above): habsjs Invalid width, please try again! Enter width (3 or above): 7 H HHHHHHH III II
