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?

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