Triangle Tessellation Code has an extra space and does not print on the same Line

Question

height = int(input())
columns = int(input())
rows = int(input())
for a in range(height):
  for b in range(a, height):
     print(" ", end="")
  for b in range(a):
     print("*", end="")
  for b in range(a+1):
    print("*", end="")
  print()   

This is my code, when I run said code, it prints a triangle with an extra space. My code can print triangles in columns but cannot print them side by side. I have tried many things to get rid of the extra space and print them side by side, but nothing has worked. Can someone help?
