我需要将MC中的JT和file1列与file2

中的列进行比较

欲望输出：

Number_of_strings

打印字符串，其中值不同

import csv

old = csv.reader(open('old.csv', 'rb'), delimiter=',')
row1 = old.next()
new = csv.reader(open('new.csv', 'rb'), delimiter=',')
row2 = new.next()

if (row1[8] == row2[8]) and (row1[9] == row2[9]):
    continue
else:
    print row1[0] + ':' + row1[8] + '!=' + row2[8]

但它确实对我不起作用

Answer 1

分隔符为而非,
您忘记使用for循环来迭代其余文件：

代码：

import csv

old = csv.reader(open('old.csv', 'rb'), delimiter=' ')
row1 = old.next()
new = csv.reader(open('new.csv', 'rb'), delimiter=' ')
row2 = new.next()

for row1, row2 in zip(old, new):
    if (row1[8] == row2[8]) and (row1[9] == row2[9]):
        continue
    else:
        print row1[0] + ':' + row1[8] + '!=' + row2[8]

使用python比较来自2个csv文件的一些列
