按行和列读取并比较2个CSV文件

Question

我有两个CSV文件。 data.csv和data2.csv。

我想首先将两个数据文件剥离成我感兴趣的数据。我已经用data.csv计算了这部分内容。然后，我想按行进行比较，以确保是否缺少一行来添加它。

接下来，我想看看第2列。如果有一个价值有那么我想写信给第3列，如果在第3列数据，然后写入4等

我现在的程序看起来像母猪。需要一些指导

哦，我使用Python V3.4

    for col in row: 
     col = col.lower()

     return -1

header = next(reader) 
header2 = next(reader2) 


"""Built a list of items to sort. If row 12 contains 'LinkRunner AT' (group 1),

stored = [] 
writer.writerow([header[0], header[3]]) 

for i, row in enumerate(reader): 
    g = find_group(row) 
    if g >= 0: 
     stored.append((g, i, row)) 
stored.sort() 

for g, i, row in stored: 
    writer.writerow([row[0], row[3]]) 

inFile.close() 
outFile.close()

也许尝试：

import csv 
with open('some.csv', 'rb') as f: 
    reader = csv.reader(f) 
    for row in reader: 
     col1.append(row[0]) 
     col2.append(row[1]) 

for i in xrange(len(col1)) 
    if col1[i] == '': 
     #thing to do if there is nothing for col1 
    if col2[i] == '': 
     #thing to do if there is nothing for col2 

这是在“确保，如果行缺少添加它开始”。
