Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting.

Answer:

Code:-  

# function to print the pattern

def draw_triangle(n, num):

     

   # base case

   if (n == 0):

       return;

   print_space(n - 1);

   print_asterisk(num - n + 1);

   print("");

 

   # recursively calling pattern()

   pattern(n - 1, num);

   

# function to print spaces

def print_space(space):

     

   # base case

   if (space == 0):

       return;

   print(" ", end = "");

 

   # recursively calling print_space()

   print_space(space - 1);

 

# function to print asterisks

def print_asterisk(asterisk):

     

   # base case

   if(asterisk == 0):

       return;

   print("* ", end = "");

 

   # recursively calling asterisk()

   print_asterisk(asterisk - 1);

   

# Driver Code

n = 19;

draw_triangle(n, n);

Output:-  

# Driver Code n = 19;| draw_triangle(n, n);
