Learning Python and need help moving a symbol with out disrupting the rest of the code

I am learning Python and need a little help with moving my symbols over a few spaces to the left. I have completed the assignment and am not looking for homework help. I just want it to look nicer on my end. In the picture that I added in the link below, you can see that the "#" is too far to the right. I would like it to sit next to the even numbers. I have tried making more spaces in my print statements but all that does is move my entire table around. How do I get that "#" to sit right next to my even numbers?

Here is my code.

#ask for user input on size of Multiplication Table.
size = int(input("What size Multiplication Table would you like? (2-10):"))
while (size <2) or (size >10):
    print("Invalid entery! Enter a Number Between 2 and 10")
    size = int(input("What size Multiplication Table would you like? (2-10):"))   
print()
print()

#dispaly header
print("                    --- Multiplication Table(",size,"x",size,") ---")
print("  ",end="")
size += 1
for h in range(1,11):
    if h == 10:
        print("    ",h, end="  ")
    else:
        print("     ",h, end="  ")
print()
for h in range(1,100):
    print('-',end='')
print()

#display Multiplication Table
#outer loop
for a in range(1,size):
    if a ==10:
        print('',a,'|',end='')
    else:
        print('',a,' |',end='')
        
#inner loop        
    for b in range(1,size):
        result = a * b
        if result >=100:
            print(' ',result, end='   ')
        elif result >=10:
            print(' ',result, end='    ')
        else:
            print('  ', result, end='    ')
            
# for putting '#' at the end of even numbers            
        if result %2==0:
            print('#', end='')
        elif result == 100:
            print('', end='')
        else:
            print(' ', end='')
    print()

I've made minimal modification to your inner loop, to produce the desired effect:

    for b in range(1,size):
        result = a * b
# for putting '#' at the end of even numbers            
        if result %2==0:
            end_str='#'
        elif result == 100:
            end_str=''
        else:
            end_str=' '
        if result >=100:
            print(' ',result, end=end_str+'   ')
        elif result >=10:
            print(' ',result, end=end_str+'    ')
        else:
            print('  ', result, end=end_str+'    ')

Output, with this modification:

        1        2        3        4        5        6        7        8        9       10

Try this:

    for b in range(1,size):
        result = a * b

        flag = " " if result % 2 else "#"
        #put the number and the flag together
        temp = f"{result}{flag}"
        #and pad the number + flag to a constant length
        print(f'   {temp:6.6}', end="")

see my comment under the question about a clearer breakdown of how f-string formatting works.

output:

                    --- Multiplication Table( 4 x 4 ) ---
        1        2        3        4        5        6        7        8        9       10

 2  |   2#       4#       6#       8#
 3  |   3        6#       9        12#
 4  |   4#       8#       12#      16#

see my comment about how f-string formatting works. couldn't find a really clear reference about how the formatting is specified f"{<variable>:<formatting-to-apply>}" so can't link one, but it do things like pad zeros and format floats too.
