Once I needed the same and I wrote:

def days_difference(s1, s2):
    splitdate = lambda s: time.strptime(s, "%Y%m%d")[:3]
    str2date = lambda s: datetime.date(*splitdate(s))
    delta = str2date(s1) - str2date(s2)
    return delta.days

print days_difference("20071112", "20061029") # 379

Although I'm sure there is a better way.
