How do I calculate a ratio from 2 numbers and return an equivalent list of about 1000

[Pleiades]

I was online at this amazing site for equivalent ratios. I would love to mimic or do the same as an output in python, but its a bit over my skills.

Can you help me put it in this format, here is what the first 3 pairs would look like in the output in python, if you can help me please?

1 : 5618 2 : 11236 3 : 16854

Here is the site that does what I want:

Here is my code so far but I hope someone can help me so it prints out in a nice fancy format or just maybe a cool list of numbers in equivalent ratio format:

It is throwing an error and I don't know why, and this is the error:
ValueError: invalid literal for int() with base 10: ' Enter 1st number for ratio calculation: '

while True:
        a = input(int(' Enter 1st number for ratio calculation: '))
        b = input(int(' Enter 2nd number for ratio calculation: '))
        r = ( a/b and b/b)
        print(r)
