如何比较2个不同csv文件中不同列的值？

import csv

# 读取CSV文件
file1 = 'file1.csv'
file2 = 'file2.csv'

data1 = []
data2 = []

with open(file1, 'r') as csvfile:
    reader = csv.reader(csvfile)
    for row in reader:
        data1.append(row)

with open(file2, 'r') as csvfile:
    reader = csv.reader(csvfile)
    for row in reader:
        data2.append(row)

# 确定要比较的列
col_index1 = 0  # 第一个CSV文件要比较的列索引
col_index2 = 1  # 第二个CSV文件要比较的列索引

# 比较列值并记录差异
differences = []

for i in range(len(data1)):
    if data1[i][col_index1] != data2[i][col_index2]:
        differences.append((data1[i][col_index1], data2[i][col_index2]))

# 输出结果
for diff in differences:
    print(f"不同的值：{diff[0]} 和 {diff[1]}")
