Python Program:

Example:

    *
  * * *
* * * * *

rows=int(input("Enter number of rows : "))
for i in range(rows,0,-1):
  for j in range(1,2*rows-i+1):
    if(j<i):
      print("  ", end="")
    else:
      print("* ", end="")
  print("")

Output:

Enter number of rows: 4

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):
      print("  ", end="")
    else:
      print("* ", end="")
  print("")

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