python max key
lambda is an anonymous function, it is equivalent to: def func(p): return p.totalScore. Now max becomes: max(players, key=func). But as def statements are compound statements they can't be used where an expression is required, that's why sometime, 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, This is because u'9' > u'10' , since they are strings. To compare numerically, use int as a key. max(MyCount, key=int). (Calling .keys() is usually unnecessary) ..., 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) ..., 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(array2)=', m.,python小记--lambda 装饰器max（min）的key回调函数sorted. 原创 2015年12月11日16:40:53. 标签：. 3476; 编辑; 删除. lambda：. lambda 输入：输出. 等价于：. def myfunc（输入）：. return 输出. 配合map filter reduce #python3里reduce不再是内建函数，需要from functools import reduce. map(lambda x:return_expression,list),max(arg1, arg2, *args[, key]). arg1 - mandatory first object for comparison (could be number, string or other object); arg2 - mandatory second object for comparison (could be number, string or other object); *args (Optional) - other objects for compariso, Copied from StackView http://stackoverflow.com/questions/18296755/python-max-function-using-key-and-lambda-expression lambda is an anonymous function, it is equivalent to: def func(p): return p.totalScore Now max becomes: max(players, key=func) But as de
