题目1：Fizz Buzz
def checkio(number
: int) -> str:
if not number
%15:
return 'Fizz Buzz'
if not number
%3:
return 'Fizz'
if not number
%5:
return 'Buzz'
return f
'{number}'
题目2：Cut Sentence
def cut_sentence(line
, length
):
if len(line
) <= length
:
return line
line1
= line
[:length
]
a
= [x
for x
in line1
.split
(' ') if x
in line
.split
(' ')]
return ' '.join
(a
)+'...'
题目3：Best Stock
def best_stock(data
: dict) -> str:
x_max
= max(data
.values
())
return [x
[0] for x
in data
.items
() if x_max
in x
][0]
其他人的答案：max中的key为一函数
def best_stock(a
):
return max(a
, key
=a
.get
)
