pattern

Main Logic :

for i in range(rows,0,-1): #rows : number of rows to print
  for j in range(1,2*rows-i+1):
    if(j==i or j==(2*rows-i) or i==1):
      print("* ", end="")
    else:
      print("  ", end="")
  print("")

You can print any thing in this pattern, just replace your value with *
