checkio题目
我们现在这儿: 丢人只解决了3道题目
-
就不按照原来的顺序了 有些题目暂时解决不了,下面按照已经解决的顺序更新答案
-
Non-unique Elements
题目要求:
解题思路:列表有一个count()方法 可以统计每个元素的个数,在加上列表推导式,所以答案呼之欲出咯
废话少说 上代码
def checkio(data: list) -> list:
# Your code here
# It's main function. Don't remove this function
# It's used for auto-testing and must return a result for check.
# 一行就搞定 利用列表推导式生成它需要的新列表 用count函数统计元素个数
return [i for i in data if data.count(i) > 1]
if __name__ == "__main__":
# These "asserts" using only for self-checking and not necessary for auto-testing
assert list(checkio([1, 2, 3, 1, 3])) == [1, 3, 1, 3], "1st example"
assert list(checkio([1, 2, 3, 4, 5])) == [], "2nd example"
assert list(checkio([5, 5, 5, 5, 5])) == [5, 5, 5, 5, 5], "3rd example"
assert list(checkio([10, 9, 10, 10, 9, 8])) == [10, 9, 10, 10, 9], "4th example"
print("It is all good. Let's check it now")
- All the Same
- 题目要求:
- 答案
from typing import List, Any
def all_the_same(elements: List[Any]) -> bool:
# your code here
# 此处用到了三目运算符和set来去重
return True if len(set(elements)) <= 1 else False
if __name__ == '__main__':
print("Example:")
print(all_the_same([1, 1, 1]))
# These "asserts" are used for self-checking and not for an auto-testing
assert all_the_same([1, 1, 1]) == True
assert all_the_same([1, 2, 1]) == False
assert all_the_same(['a', 'a', 'a']) == True
assert all_the_same([]) == True
assert all_the_same([1]) == True
