Right-Aligned Triangle - Python Programming Exercise

In this exercise, you will develop a Python program that prompts the user for a string and displays a right-aligned triangle. This exercise is perfect for practicing string manipulation and loops in Python. By prompting the user for a string and displaying it in a right-aligned triangular format, you will gain hands-on experience in handling user input and output in Python. This exercise not only reinforces your understanding of string manipulation but also helps you develop efficient coding practices for managing user interactions.

Right-Aligned Triangle

 Objective

Develop a Python program that prompts the user for a string and displays a right-aligned triangle:

n
an
uan
Juan

 Example Python Exercise

 Copy Python Code 
# Main program loop
while True:
    user_input = input("Enter a string: ")
    
    # Initialize variable for the length of the string
    length = len(user_input)

    # Loop through each character in the string
    for i in range(1, length + 1):
        # Create a substring and right-align it
        substring = user_input[:i]
        print(substring.rjust(length))

    break

 Output

Enter a string: Juan
   J
  Ju
 Jua
