you may try the code as below

input = 100.56
print(input % 1)

you could refer to the answer at How to get numbers after decimal point?

Try to avoid use `input` built-in function as your variable name. – Python learner Oct 13 '21 at 15:06

that was just an example. but yea input as a variable name is not a good idea though. thanks – Ramieeee Oct 13 '21 at 15:20

If you want to have only the original decimal part, you can do :

inputFloat = 25189456.1584566
decimalPart = '.' + str(inputFloat).split('.')[1]
print(decimalPart)

Something like this should work

def f(x, decimals=2):
    r = str(round(x, decimals)) #round and convert to string
    r = r.split('.')[-1] #split at the dot and keep the decimals
    r = '.' + r #add the dot
    return r

f(100.56789) #.57

[f(x) for x in [100.56, 455.345, 89.5]] #['.56', '.35', '.5']

The one-liner would be '.' + str(round(x, 2)).split('.')[-1] or f".{str(round(x, 2)).split('.')[-1]}" where x is the float you are interested in.
