Question

Question 1: Pine Tree Write a program that, prints a 'pine tree' consisting of triangles of increasing sizes, filled with a character (' oror '$' etc). Your program should consist of three functions: 1. A function print_shifted_triangle (n, m, symbol). It prints an n-line triangle, filled with symbol characters, shifted m spaces from the left margin. For example, if we call print_shifted_triangle (3, 4, +"), the expected output is: +++ Left margin +++++ 4 spaces 2. A function print_pine_tree (n, symbol).It prints a sequence of n triangles of increasing sizes (the smallest triangle is a 2-line triangle), which form the shape of a pine tree. The triangles are filled with the symbol character For example, if we call print_pine_tree (3, #),the expected output is: ### Left margin # ## 3. A main function that interacts with the user to read the number of triangles in the tree and the character filling the tree.

Using Python Please

Answer 1

'''
Python version : 3.6
Python program to print pine tree of given number of triangles and given symbol
'''

def print_shifted_triangle(n,m,symbol):
   '''
   It prints an n-line triangle , filled with symbol characters,
   shifted m spaces from the left margin
  
   '''
   for i in range(n):
       space = ' '*(m+n-1-i)
       pattern = symbol*(2*i+1)
       print(space+pattern)
      
def print_pine_tree(n, symbol):
   '''
   It prints a sequence of n triangles of increasing sizes
   (the smallest triangle is a 2-line triangle), which forms
   the shape of a pine tree. The triangles are filled with the symbol character.
   '''
   for i in range(n):
       print_shifted_triangle(2+i,n-i-1,symbol)
      
      
def main():
   # input the number of triangles
   n = int(input('Enter the number of triangles : '))
   # input the character to fill the tree with
   symbol = input('Enter the character to fill the tree : ')
   # call the function print_pine_tree to display the pine tree
   print_pine_tree(n,symbol)

# call the main function  
main()  
# end of program

Output:
