Python - 一些有趣的语句

持续更新...

函数

1、找出一个list中的最小和最大值，并返回一个tuple

def findMinAndMax(L):
    min = L and L[0] or None
    max = L and L[0] or None
    for x in L:
        min = min > x and x or min
        max = max < x and x or max
    return (min, max)

 

2、利用filter()筛选出回数

def is_palindrome(s):
    s = str(s)
    return s == s[::-1]

if __name__ == '__main__':
    output = filter(is_palindrome, range(1, 1000))
    print('1~1000:', list(output))
