Pandas读取表格数据进行处理

import pandas as pd

df_policy = pd.read_excel(‘e:\policy.xlsx‘)
df_sh01 = pd.read_csv(‘e:\sh01.csv‘, encoding=‘gbk‘)

list_not = []
set_found = set()

for i in range(df_sh01[‘目的IP‘].__len__()):
    flag = True
    for j in range(df_policy[‘目标地址‘].__len__()):
        if df_sh01[‘目的IP‘][i] in df_policy[‘目标地址‘][j] and str(df_sh01[‘目的端口‘][i]) in df_policy[‘协议-端口‘][j]:
            flag = False
            set_found.add(df_policy[‘ID‘][j])
    if flag:
        list_not.append([df_sh01[‘目的IP‘][i], df_sh01[‘目的端口‘][i]])
pd.DataFrame(list_not).to_csv(‘e:\out.csv‘)
print(list_not.__len__())
print(set_found.__len__(), set_found)
