调用函数检查文件内容，大小等的内容
1. 如果文件大小已更改，则调用功能；如果文件大小已更改，则检查文件内容，将更改添加到列表中或从列表中删除问如何在其他函数中正确使用变量？

import re
import os
from time import sleep

hosts_file = "hosts.txt"

class Hosts(object):

    def __init__(self):
        self.hosts_file = hosts_file

    def get_file_size(self):
        f_size = os.stat(self.hosts_file)
        return f_size.st_size

def work_with_hosts_file():
    host_file_work = Hosts()
    file_size = host_file_work.get_file_size()
    return file_size # use this var

def compare_hosts_file_size(): # in this function
    host_file_work = Hosts()
    file_size_check = host_file_work.get_file_size()
    if file_size != file_size_check:
        #do stuff        

if __name__ == "__main__":
    work_with_hosts_file()
    get_connection_hosts_info()
    while True:
        compare_hosts_file_size()
        sleep(5.0)

谢谢您！
