我可以做<代码>max(s),以确定顺序的大小。 但恳请我根据我自己的职责来赞扬这一大事,例如:

currmax = 0
def mymax(s):
  for i in s :
    #assume arity() attribute is present
    currmax = i.arity() if i.arity() > currmax else currmax

这样做是否有干净的onic?

问题回答
max(s, key=operat或.methodcaller( arity ))

max(s, key=lambda x: x.arity())

例如,

max (i.arity() for i in s)

您仍可使用<代码>max功能:

max_arity = max(s, key=lambda i: i.arity())

我认为,创造力的双倍制表现较好,但我们很少使用手法。

from operator import methodcaller
max(map(methodcaller( arity ), s))
