所以我有一个多行文本文件 每行都有姓名、年级和出生年份或学生，用分号分隔
如何创建一个函数，以便对每行中的所有第二项求和，然后对它们求平均值？
例如，
mary; 0; 1995
jay; 50; 1995
classAverage = 25
对此真的很困惑。
到目前为止，这是我的代码，它没有给我错误，但是当我打印时，它显示 <function classAverage at 0x0000000004C1ADD8>
from kiva.constants import LINES
def process(name):
f = open(name)
answer = []
for line in f:
answer.append(line.strip())
return answer
def classAverage(data):
data = process(filename)
data.split()
adding = []
for line in data:
adding = adding + data[1]
return adding/(line)
if __name__ == '__main__':
filename = "grades.txt"
data = process(filename)
for each in data:
print each
print classAverage(data)
#print "Average grade is ", classAverage(data)
year1 = 1995
year2 = 1997
print "Number born from ",year1,"to",year2,"is",
#print howManyInRange(data, year1, year2)
最佳答案
def ave(x):
return sum(x) / len(x)
with open(name, newline='') as csvfile:
print(ave([float(row[1]) for row in csv.reader(csvfile, dilimeter=';')]))
