Python 3.x 类型错误：'；int'；对象在计算平均值时不可计算

我试图从文件中读取不同的值，并将它们存储在列表中。在那之后，我需要取他们的平均值，这样我就得到了上面的错误。代码正在运行到第行

"Avg_Humidity.append(words[8])"

这是：

def monthly_report(path,year,month):
    pre_script="Murree_weather"
    format='.txt'
    file_name = pre_script + year + month+format
    name_path=os.path.join(path,file_name)
    file = open(name_path, 'r')
    data = file.readlines()
    Max_Temp = []
    Min_Temp = []
    Avg_Humidity = []
    for line in data:
        words = line.split(",")
        Max_Temp.append(words[1])
        Min_Temp.append(words[3])
        Avg_Humidity.append(words[8])
    Count_H, Count_Max_Temp, Count_Min_Temp, Mean_Max_Temp, Mean_Min_Temp, 
    Mean_Avg_Humidity=0
    for iterate in range(1,len(Max_Temp)):
        Mean_Max_Temp= Mean_Max_Temp+Max_Temp(iterate)
        Count_Max_Temp=Count_Max_Temp+1
    Mean_Max_Temp=Mean_Max_Temp/Count_Max_Temp
    for iterate in range(1,len(Min_Temp)):
        Mean_Min_Temp= Mean_Min_Temp+Min_Temp(iterate)
        Count_Min_Temp=Count_Min_Temp+1
    Mean_Min_Temp=Mean_Min_Temp/Count_Min_Temp
    for iterate in range(1,len(Avg_Humidity)):
        Mean_Avg_Humidity= Mean_Avg_Humidity+Avg_Humidity(iterate)
        Count_H=Count_H+1
        Mean_Avg_Humidity=Mean_Avg_Humidity/Count_H
    print("Mean Average Humidity = ",Mean_Avg_Humidity)
    print("Mean Maximum Temperature = ",Mean_Max_Temp)
    print("Mean Minimum Temperature = ",Mean_Min_Temp)
    return

这行不正确：

    Count_H, Count_Max_Temp, Count_Min_Temp, Mean_Max_Temp, Mean_Min_Temp, Mean_Avg_Humidity = 0

若要修复，请将其更改为：

    Count_H = Count_Max_Temp = Count_Min_Temp = Mean_Max_Temp = Mean_Min_Temp = Mean_Avg_Humidity = 0

另一种修复方法是保持逗号不变，并将右侧更改为一个与左侧元素数相同的列表或零元组。但这不太清楚，也更难维护。

在这里，我还必须跳过列表的第一个元素，因为列表的第一个元素是字符串，其余元素是整数。那么，max_temp、Min_temp和Avg_湿度是整数吗？如果是，则在for循环中删除len函数no Max_temp、Min_temp和Avg_湿度是3个不同的列表您可以编辑问题的完整回溯吗？
