实验五

任务六：

代码：

with open('data6.csv','r',encoding='gbk') as f:
    data = f.readlines()
data1 = [str(eval(data[i])) for i in range(1,len(data))]
data2 = [str(int(eval(data[i])+0.5)) for i in range(1,len(data))]
info = [[data1[i],data2[i]] for i in range(len(data1)) ]
title = ['原始数据','四舍五入后数据']

with open('data6_processed.csv', 'w', encoding = 'gbk') as f:
    f.write(','.join(title) + '\n')
    for item in info:
        f.write(','.join(item) + '\n')
print('原始数据')
print(data1)
print('四舍五入后数据')
print(data2)

    data = f.read()

count1 = 0
for i in data:
    if i == '\n':
        count1 += 1
