和下面的python脚本：

map = {} 
lines=open("new_data.csv",'r').read().splitlines() 
for l in lines: 
    data = l.split('"Overall evaluation:') 
    if len(data) == 2: 
     if data[0] not in map.keys(): 
      map[data[0]] = (0,0) 
     map[data[0]] = (map[data[0]][0]+int(data[1]) , map[data[0]][1]+1) 
for x, y in map.items(): 
    print(str(x) + ", " + str(y[0]/y[1])) 

什么，我认为正在发生的事情是，它需要的两个Overall evaluation:数字的平均值并将其输出到提交号码旁边，是否正确？

Answer 1

您的map值是每个元组对应于所看到的项目数和相同项目看到的所有值的总和。

划分两个确实会返回平均值（尽管因为它们是整数，所以结果是四舍五入的 - 如果想要浮点结果而不是整数结果，可以考虑将一个或两个都转换为浮点）。
