使用python实现俩个csv文件内容对比_python csv文件中字段的值对比

背景：实现一个csv文件内容对比的脚本，输出相同的数据总数，以及输出不相同的数据

前期准备：

data_detail.csv的数据11条

代码具体实现：

​#!/usr/bin/python
# -*- coding: UTF-8 -*-
import csv
 
 
def  compa ():
    with open("data_detail.csv","r", encoding="utf-8") as f :
        red = csv.reader(f)
        count = 0
        for r in red:
            flag = 0
            with open("data.csv",encoding="utf-8") as  n:
                dat = csv.reader(n)
                for d in dat:
                    if r == d:
                       count = count+1
                       flag=1
                       break
 
                if flag == 0:
                    print(r)
        print("相同的数据总共有：", count)
 
 
if __name__ == "__main__":
    compa()
 

注：flag的作用是判断如果flag=0证明没有相同的数据，则输出不相同的数据

结果：
