i<b: #可依需要修改条件 num+=1 percent = num/len(a) return num,percent #调用 LowerCount(

进一步的:
#输入data(可迭代的序列或集合),number(阈值),operator(运算符’<’、>’、’=’)
#输出计数和百分比
def OperCount(data,number,operator): #compelete with a number num = 0 if

in data: if i < number: num+=1 elif operator == '=': for i in data: if i ==
number: num+=1 else: print('something wrong!') percent = num/len(data) return
num,percent #调用 OperCount(alist,80,'<')
暂时搞不懂如何将运算符直接作为参数传递,以上就是个简单的循环,总觉得这样的运算应该有简单粗暴的函数直接使用的,然而找的时间还不如写的快=
=如果你都看到我写的了,赶紧别找了哈哈哈哈(不过以防万一:找到的铁子请留言曝光那个函数!!)
