Print a triangle

Question： you need to print a triangle like this:

     #
    ##
   ###
  ####
 #####
######

Ideas:

1. Think of this like a square

-----#
----##
---###
--####
-#####
######

2. we need to print the left triangle first

for i in range(0,n):
  for j in range(0,n-i-1):
    print("-",end=" ")
  print("")

3. now we can print the right triangle easier

for i in range(0,n):
  for j in range(0,n-i-1):
    print("-",end="")
  for j in range(0,i+1):
    print("*",end="")
  print("")

4. change "-" to ""

def staircase(n):
    # Write your code here
    for i in range(0, n):
        for j in range(0, n-i-1):
            print("-",end="")
            # print("",end = " ")
        for j in range(0, i+1):
            print("#",end="")
        # if i<n:
        print('')
