Checking number patterns in Python

Question

How can I check in Python whether a number is built in this pattern:

1. 57.00057  
2. 611.000000611  
3. 389.00003890000389

There's the number, then a certain number of zero's after the dot and then the number again. This can occur multiply times after the dot (Like in example 3).

def test(number):
    return bool(re.match(r'^(\d+)\.(0+\1)+$', number))
