A basic implementation without regular expressions:
>>> def picture(s, pic, placeholder="@"):
... parts = pic.split(placeholder)
... result = [None]*(len(parts)+len(s))
... result[::2] = parts
... result[1::2] = s
... return "".join(result)
...
>>>
>>> picture("123456789", "(@@@)-@@-(@@@)[...@]")
'(123)-45-(678)[9]'
