list = [{"name":"hello","age":12},{"name":"world","age":5},{"name":"today","age":23}] list.sort(key=lambda x:x["age"]) print(list)
匿名函数当做实参
def test(a,b,func): result = func(a,b) return result num = test(11,22,lambda x,y:x+y) print(num)
匿名函数的应用
def test(a,b,func): result = func(a,b) return result func_new = input("请输入一个匿名函数:") func_new = eval(func_new) num = test(11,22,func_new) print(num)
