Python里csv怎么计算平均值

计算AGE的平均值

你好,求和代码如下

with open(' survey_ 1000. csv', 'r') as csvfile:
    csv_reader = csv.reader(csvfile, delimiter=',' )
    header_row = next(csv_reader)
    AGE= []
    avgnumber=0
    for row in csv_reader:
        avgnumber+=1
        AGE.append(int(row[91]))
    sum = str(sum(AGE))
    avg = str(sum(AGE)/avgnumber)
    print(sum)
    print(avg)
