Question

* Write a program texttriangle.py. in python

This, too, is not a graphics program. Prompt the user for a small positive integer value, that I’ll call n. Then use a for-loop with a range function call to make a triangular arrangement of ‘#’characters, with n ‘#’ characters in the last line. Hint: [5]

Then leave a blank line. Then make a similar triangle, except start with the line with n ‘#’ characters. To make the second triangle, you can use a for-loop of the form discussed so far, but that is trickier than looking ahead to The Most General range Function and using a for-loop where a range function call has a negative step size.

Answer 1

# Function to demonstrate triangle
def texttriangle(n):
   # outer loop to handle number of rows
   # n in this case
   for i in range(0, n):
  
       # inner loop to handle number of columns
       # values changing acc. to outer loop
       for j in range(0, i+1):
      
           # printing stars
           print("# ",end="")
  
       # ending line after each row
       print("\r")
      
   ##Leave a blank line
   print("\r");
   # outer loop to handle number of rows
   # n in this case
   for i in range(n, 0, -1):
  
       # inner loop to handle number of columns
       # values changing acc. to outer loop
       for j in range(0 , i ):
      
           # printing stars
           print("# ",end="")
  
       # ending line after each row
       print("\r")

# Driver Code
n = int(input("Enter positive integer value \n"));
texttriangle(n)

Output:
