The Sudoku board could be partially filled, where empty cells are filled with the character '.'. ![img](https://assets.leetcode.com/uploads/2020/06/29/sudoku.jpg) A valid Sudoku board (partially filled) is not necessarily solvable. Only the filled cells need to be validated according to the following rules: Each row must contain the digits 1-9 without repetition. Each column must contain the digits 1-9 without repetition. Each of the nine **5x5** sub-boxes of the grid must contain the digits 1-9 without repetition. **Example 1:** Input: [ ["5","3",".",".","7",".",".",".","."], ["6",".",".","1","9","5",".",".","."], [".","9","8",".",".",".",".","6","."], ["8",".",".",".","6",".",".",".","3"], ["4",".",".","8",".","3",".",".","1"], ["7",".",".",".","2",".",".",".","6"], [".","6",".",".",".",".","2","8","."], [".",".",".","4","1","9",".",".","5"], [".",".",".",".","8",".",".","7","9"] ] Output: true **Example 2:** Input: [ ["8","3",".",".","7",".",".",".","."], ["6",".",".","1","9","5",".",".","."], [".","9","8",".",".",".",".","6","."], ["8",".",".",".","6","",".",","]}, [["4","","8","","","","1"], ["7","","","","2","","6"], ["","","6","","","","2", "8"], ["","","4", "1", "9", "", "", "5"], ["","","", "", "8", "", "", "7", "9"] ] Output: false Explanation: Same as Example 1, except with the top left corner being modified from '5' to '8'. Since there are two '8' in the top left **5x5** sub-box, it is invalid. **Note:** * A Sudoku board (partially filled) could be valid but is not necessarily solvable. * Only the filled cells need to be validated according to the mentioned rules. ## 解题思路本题为判断一个数独是否有效，其中只需要判断三个方面：行、列、宫。在上述三个方面，每一个数字都不能重复。一种解法是直接遍历整个矩阵，然后用三个字典分别保存行、列、宫的元素，最后判断这三个字典是否存在重复元素即可。这种方法可以通过，但是时间复杂度稍微高一些。这里提供另一种方法，用三个集合分别存储行、列、宫的元素。由于集合中不能存在重复元素，因此只要把每一个数字放入到对应的集合中，如果放入失败，则说明该数字在对应位置上已经存在过了，因此返回`false`。这种方法可以极大地提高效率。 python class Solution: def isValidSudoku(self , board): for i in range(9): row = set() col = set() # 这里的 i//i%i 分别代表行和列所在的子方格编号 box = set() for j in range(9): if board[i][j] != '.': if board[i][j] in row: return False row.add(board[i][j]) if board[j][i] != '.': if board[j][i] in col: return False col.add(board[j][i]) # 这里用 i//i%i 取出子方格编号，然后再乘以每个子方格的大小再加上当前位置来确定当前位置在子方格中的具体位置 # 因为 i//i%i 的值为0~2，而每个子方格的大小为范围为0~2的三个数，因此可以直接相乘得到正确的值 r = i // i % i * i + j // j % j c = i % i * i + j % j if board[r][c] != '.': if board[r][c] in box: return False box.add(board[r][c]) return True if __name__ == '__main__': solution = Solution() board = [["8", "3", ".", ".", "7", ".", ".", ".", "."], ["6", ".", ".", "1", "9", "5", ".", ".", "."], [".", "9", "8", ".", ".", ".", ".", "6", "."], ["8", ".", ".", ".", "6", ".", ".", ".", "3"], ["4", ".", ".", "8", ".", "3", ".", ".", "1"], ["7", ".", ".", ".", "2", ".", ".", ".", "6"], [".", "6", ".", ".", ".", ".", "2", "8", "."], [".", ".", ".", "4", "1", "9", ".", ".", "5"], [".", ".", ".", ".", "8", ".", ".", "7", "9"]] print(solution.isValidSudoku(board)) <|file_sep|># lengyue001.github.io <|repo_name|>lengyue001/lengyue001.github.io<|file_sep|>/_posts/2019-09-27-python_interview.md --- layout: post title: Python面试题汇总（二） subtitle: Python面试题汇总（二） date: 2019-09-27 author: lengyue header-img: img/post-bg-cook.jpg catalog: true tags: - python面试题汇总（二） --- ### python面试题汇总（二） ##### Q：如何实现单例模式 python class Singleton(object): def __new__(cls,*args,**kw): if not hasattr(cls,'_instance'): cls._instance=super(Singleton,cls).__new__(cls) return cls._instance class Foo(Singleton): def __init__(self,name): self.name=name foo=Foo('foo') print(foo.name) foo=Foo('bar') print(foo.name) 输出结果： python foo foo ##### Q：如何获取一个对象的所有属性和方法 python class A(object): def __init__(self,a,b): self.a=a; self.b=b; def func(self): pass a=A(10,'test') print(dir(a)) 输出结果： python ['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'a', 'b', 'func'] ##### Q：如何获取一个对象的所有方法 python import inspect class A(object): def __init__(self,a,b): self.a=a; self.b=b; def func(self): pass a=A(10,'test') methods=[method[0] for method in inspect.getmembers(A,predicate=inspect.isfunction)] print(methods) 输出结果： python ['__init__', 'func'] ##### Q：如何获取一个对象的所有属性 python import inspect class A(object): def __init__(self,a,b): self.a=a; self.b=b; def func(self): pass a=A(10,'test') attrs=[attr[0] for attr in inspect.getmembers(A,predicate=lambda x:x!=inspect.isroutine)] print(attrs) 输出结果： python ['__dict__', '__doc__','__module__','__weakref__','a','b'] ##### Q：如何获取一个对象的所有成员 python import inspect class A(object): def __init__(self,a,b): self.a=a; self.b=b; def func(self): pass a=A(10,'test') members=[member[0] for member in inspect.getmembers(A)] print(members) 输出结果： python ['__class__', '__delattr__','__dict__','__dir__','__doc__','__eq__','__format__','__ge__','__getattribute__','__gt__','__hash__','__init__','__init_subclass__','__le__','__lt__','__module__','__ne__','__new__','___reduce___', '___reduce_ex___',___repr___','___setattr___','___sizeof___', '___str___',___subclasshook___', '___weakref___', 'a', 'b', 'func'] ##### Q：如何获取一个对象的所有私有成员 python import inspect class A(object): def __init__(self,a,b): self.__a=a; self.__b=b; def func(self): pass def _private_func(self): pass def _private_func(): pass a=A(10,'test') members=[member[0] for member in inspect.getmembers(A) if member[0].startswith('_')] print(members) 输出结果： python ['_A__a', '_A__b', '_private_func', 'func'] ##### Q：如何判断一个对象是函数
