Question

modify the program to use a nested loop to output a right triangle of height triangle_height. the first line will have one user - specified character. each subsequent line will have one additional user - specified character until the number in the triangles base reaches triangle_height. output a space after each user - specified character, including after the lines last user - specified character. submit for grading to confirm all tests pass. ex: if triangle_char = % and triangle_height = 5, the output is: enter a character: % enter triangle height: 5

Explanation:

Here is the Python code to achieve the above - described functionality using nested loops:

triangle_char = input("Enter a character: ")
triangle_height = int(input("Enter triangle height: "))

for i in range(1, triangle_height + 1):
    for j in range(i):
        print(triangle_char, end=' ')
    print()

In the above code:

Step1: Get user input

The program first prompts the user to enter a character (triangle_char) and the height of the triangle (triangle_height). The character is read as a string and the height is converted to an integer.

triangle_char = input("Enter a character: ")
triangle_height = int(input("Enter triangle height: "))

Step2: Outer loop for rows

The outer for loop iterates from 1 to triangle_height + 1. This loop controls the number of rows in the triangle. Each iteration represents a new row in the triangle.

for i in range(1, triangle_height + 1):

Step3: Inner loop for columns

The inner for loop iterates from 0 to i (where i is the current row number). This loop controls the number of characters in each row. In each iteration of the inner loop, it prints the triangle_char followed by a space.

    for j in range(i):
        print(triangle_char, end=' ')

Step4: Move to next line

After the inner loop finishes for a particular row, the print() statement (without any arguments) is used to move the cursor to the next line so that the next row can be printed below the current one.

    print()

Answer:

The above Python code will output the right - angled triangle as per the requirements. For example, if the user enters % as the character and 5 as the height, it will output:

%
% %
% % %
% % % %
% % % % %
