>>> s = "some chars like 987 before the bracket (3.12345) etc"
>>> x = re.search("[0-9.]+", s)
>>> x.group(0)
'987'

OP sez: "I need to get the content inside the bracket"
OP sez: "I need to get whatever inside the ()"

My interpretation:

>>> for s in ['foo(123)bar', 'foo(123))bar', 'foo()bar', 'foobar']:
...     x = re.search(r"\([^)]*\)", s)
...     print repr(x and x.group(0)[1:-1])
...
'123'
'123'
''
None
