Problem 7: Double Eights (100pts)

Write a function that takes in a number and determines if the digits contain two adjacent 8s. (Reviewing Problem 4 and 5 in Lab 01 might be helpful here!)

def double_eights(n):
    """Return true if n has two eights in a row.
    
    >>> double_eights(8)
    False
    >>> double_eights(88)
    True
    >>> double_eights(2882)
    True
    >>> double_eights(880088)
    True
    >>> double_eights(12345)
    False
    >>> double_eights(80808080)
    False
    """
