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:
