写一个算法，取一个数组并将所有零移到末尾，保留其他元素的顺序

move_zeros([false,1,0,1,2,0,1,3,"a"]) # returns[false,1,1,2,1,3,"a",0,0]

我的代码：

def move_zeros(array):
    zero_count = array.count(0)
    array1 = list(filter(lambda a: a != 0, array)) + [0 for i in range(zero_count)]
    return array1

样本测试：

Test.describe("Basic tests")
Test.assert_equals(move_zeros([1,2,0,1,0,1,0,3,0,1]),[ 1, 2, 1, 1, 3, 1, 0, 0, 0, 0 ])
Test.assert_equals(move_zeros([9,0.0,0,9,1,2,0,1,0,1,0.0,3,0,1,9,0,0,0,0,9]),[9,9,1,2,1,1,3,1,9,9,0,0,0,0,0,0,0,0,0,0])
Test.assert_equals(move_zeros(["a",0,0,"b","c","d",0,1,0,1,0,3,0,1,9,0,0,0,0,9]),["a","b","c","d",1,1,3,1,9,9,0,0,0,0,0,0,0,0,0,0])
Test.assert_equals(move_zeros(["a",0,0,"b",None,"c","d",0,1,False,0,1,0,3,[],0,1,9,0,0,{},0,0,9]),["a","b",None,"c","d",1,False,1,3,[],1,9,{},9,0,0,0,0,0,0,0,0,0,0])
Test.assert_equals(move_zeros([0,1,None,2,False,1,0]),[1,None,2,False,1,0,0])
Test.assert_equals(move_zeros(["a","b"]),["a","b"])
Test.assert_equals(move_zeros(["a"]),["a"])
Test.assert_equals(move_zeros([0,0]),[0,0])
Test.assert_equals(move_zeros([0]),[0])
Test.assert_equals(move_zeros([False]),[False])
Test.assert_equals(move_zeros([]),[])

运行后的我的输出：

• 测试通过

• 测试通过

• 测试通过

• ['a'，b'，None'，c'，d'，1,1,3，[]，1,9，{}，9,0,0,0,0,0,0,0,0,0,0,0]应该等于['a'，b'，None'，c'，d'，1,False，1,3，[]，1,9,9,0,0,0,0,0]/p>

• [1，无，2，1，0，0，0]应该等于[1，无，2，False，1，0，0]

• 测试通过

• 测试通过

• 测试通过

• 测试通过

• 测试通过

• 测试通过

我的问题：

为什么我的答案没有通过这两项测试

Answer 1

因为您刚刚退出了a != 0中的所有FalseFalse是0，0是False

进一步详情：Is False == 0 and True == 1 an implementation detail or is it guaranteed by the language?

Answer 2

将所有值更改为字符串，然后执行该函数

Answer 3

你需要

def move_zeros(array):
    zero_count = array.count(0)
    array1 = list(filter(lambda a: a != 0 or isinstance(a, bool), array)) + [0 for i in range(zero_count)]
    return array1
