python简单日志统计

业务场景：在一个目录里，有许多日志文件，里面是一条条的json数据，格式如下，为防止一个账号被多个ip使用，现在我想知道：哪些用户登录了哪些ip，和哪些ip登录了哪些用户，如果一个ip对应一个用户，就不展示了

import json, os, sys

ip_map = {}
email_map = {}
path = 'E:/GoogleDownload/'  #日志路径
type =  # :countByIp  :countByEmail

def countByIp(line):
    try:
        if line['ip'] in ip_map.keys():

            ip_v_map = ip_map[line['ip']]
            if line['email'] in ip_v_map.keys():
                new_email_count = ip_v_map[line['email']] +
                ip_v_map[line['email']] = new_email_count

            else:
                ip_v_map[line['email']] =
            ip_map[line['ip']] = ip_v_map

        else:
            ip_v_map = {}
            ip_v_map[line['email']] =
            ip_map[line['ip']] = ip_v_map
    except:
        print("countByIp error: %s"%line)

def countByEmail(line):
    try:
        if line['email'] in email_map.keys():

            email_v_map = email_map[line['email']]
            if line['ip'] in email_v_map.keys():
                new_ip_count = email_v_map[line['ip']] +
                email_v_map[line['ip']] = new_ip_count

            else:
                email_v_map[line['ip']] =
            email_map[line['email']] = email_v_map

        else:
            email_v_map = {}
            email_v_map[line['ip']] =
            email_map[line['email']] = email_v_map
    except:
        print("countByEmail error: %s"%line)

def getResult(file, type):
    fr = open(path+file, "r")

    line = fr.readline()
    line = json.loads(line)
    if type == :
        countByIp(line)
    elif type == :
        countByEmail(line)
    else:
        return

    i =
    while line:
        line = fr.readline()
        if line == "" or line is None:
            continue

        i +=
        line = json.loads(line[:-])
        if type == :
            countByIp(line)
        elif type == :
            countByEmail(line)
        else:
            return

    print("读取%s, 行数：%s"%(file,i))
    fr.close()

if __name__ == "__main__":

    for f in os.listdir(path):
        if os.path.isfile(os.path.join(path, f)) and str(f).endswith('.log'):
            getResult(str(f), type)

    fw_ip = open(path + "result_ip.txt", "w")
    fw_email = open(path + "result_email.txt", "w")

    for ip in list(ip_map):
        if  == len(ip_map[ip]):
            ip_map.pop(ip)

    for ip in list(email_map):
        if  == len(email_map[ip]):
            email_map.pop(ip)

    fw_ip.write(str(ip_map))
    fw_email.write(str(email_map))

    fw_ip.close()
    fw_email.close()

最后，结果如下

当前ip被哪些用户登录了多少次

当前用户在哪些ip上登录过多少次
