Tīmeklislambda 创建一个匿名函数。 冒号前面是传入参数，后面是一个处理传入参数的单行表达式。 调用lambda函数返回表达式的结果。 list的sort 同于内建函数sorted。 它有三个参数cmp，key，reverse，均有默认值。 cmp是一个比较器，自定义比较器的话传入两个参数x，y，返回值限制为1 (x>y), 0 (x=y)， -1 (x Tīmeklis(lambda x: x + 1) (2) = lambda 2: 2 + 1 = 2 + 1 = 3 Because a lambda function is an expression, it can be named.
