当且仅当一个数字至少有两个连续的数字，每个数字等于3，或者其最后一个数字可被4整除时，该数字才不苍白

Question

def pale(n):
    '''(int)->bool
    return A number is not pale if and only if it has at least two consecutive digit divisible by 4.
  
    >>> pale(1128)
    Fasle
    >>> pale(3443)
    True
    '''
    return n%4!=0 and n!=33
   
print(pale(5433))

但答案5433中的错误是错误的，但答案是正确的。请推荐给我

Answer 1

您必须查看n的每个数字，而不是整个数字：

def pale(n):
    sym = str(n)
    for idx in range(len(sym)-1): # For each digit in the number n
        if int(sym[idx])%4 == 0: # if the digit is divisible by 4
            if int(sym[idx+1])%4 == 0: # and if the next one is divisible by 4
                return True
    return False
