和下面的python腳本：

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])) 

什麼，我認爲正在發生的事情是，它需要的兩個Overall evaluation:數字的平均值並將其輸出到提交號碼旁邊，是否正確？

Answer 1

您的map值是每個元組對應於所看到的項目數和相同項目看到的所有值的總和。

劃分兩個確實會返回平均值（儘管因爲它們是整數，所以結果是四捨五入的 - 如果想要浮點結果而不是整數結果，可以考慮將一個或兩個都轉換爲浮點）。
