如何找到数组的平均值并将多个值存储在数组中

Question

如何将我的程序的多个结果存储在一个数组中？
对于数组中的每个人，我需要存储 3 个结果，但每次我这样做时，当程序为运行.

时，我都会收到错误消息

程序为运行时，我找不到3个数组中每个人的平均分。

我是 PYTHON 的新手。

import operator 
print("if form1 enter x, if form2 enter y,if form 3 enter z")
print("to view all results enter allscore")
x={"guv":1,"jane":4,"adam":5,"luiz":8,"elizabeth":9,"paul":10,"guv":3}

sorted(x.items(), key=operator.itemgetter(1), reverse=True) #sorts x from high to low

sorted(x.items()) #sorts x alphabetically

y={"adrian":0,"anna":9,"david":7,"matt":10,"micheal":5}

sorted(y.items(), key=operator.itemgetter(1), reverse=True)

sorted(y.items())

z={"gus":6,"mohammed":6,"winston":9,"barry":9,"ping":3}

sorted(z.items(), key=operator.itemgetter(1), reverse=True)

sorted(z.items()) # 

allscore={} 

allscore.update(x) # to get data from array x
allscore.update(y) # to get data from array y
allscore.update(z) # to get data from array z
#stores all data in this array

如果要为每个用户存储多个值，可以使用tuples。

scores = {
    "guv": (1, 2, 3),
    "jane": (4, 5, 6),
    "luiz": (7, 8, 9),
}

然后您可以使用以下循环获取所有用户的平均值：

for name in scores:
    average = sum(scores[name]) / len(scores[name])
    print("Average for " + name + ": " + str(average))

如果您希望能够添加分数，请改用 lists。

按字母顺序打印分数：

for name in sorted(scores):
    print("Scores for " + name + ": " + str(scores[name]))

用于打印从最高平均分到最低平均分的分数：

averages = {
    name: sum(scores[name]) / len(scores[name])
    for name in scores.keys()
}
for name in sorted(averages, key=averages.get, reverse=True):
    print("Average score for " + name + ": " + str(averages[name]))
