python max key
The code you have written is my_dict = 'a':2,'b':1} min(my_dict, key=my_dict.get). actually this works on min function. so, what does min do? min(a, b, c, ...[, key=func]) -> value. With a single iterable argument, return its lowest it, The key is used to pass a custom comparison function. Example: output max by length of list, where arg1, arg2 are both lists. >>> max([1,2,3,4], [3,4,5], key=len) [1, 2, 3, 4]. Example: output max by sum of elements of args' lists >>&g

Python 的内置函数max, min, sorted 都支持参数key,要求参数key是一个函数,该只接收一个参数(也就是该内置函数要处理的元素),key函数返回的结果作为比较大小或排序的依据。 注意,一定不要忘记了key参数是keyword argument,这三个函数都接收多个position arguments。 x = [-1, -2, -3] max(x, key=abs)&nbs... http://zhoufeng1989.github.io Python标准库:内置函数max(iterable, *[, key, default]) - CSDN
max(arg1, arg2, *args[, key]) 本函数是迭代对象iterable进行比较,找出最大值返回。当key参数不为空时,就以key的函数对象为判断的标准。例子:#max() array1 = range(10) array2 = range(0, 20, 3) print('max(array1)=', max(array1)) print('max(... http://blog.csdn.net python小记--lambda 装饰器max(min)的key回调函数sorted - CSDN博客
