Python counts the number of occurrences of each IP in the log

Introduces the method of Python to count the number of occurrences of each IP in the log, and analyzes the relevant skills of Python based on regular expression parsing log files. Friends who need it can refer to the following

This script can be used for various log types

#-*- coding:utf-8 -*-
import re,time
def mail_log(file_path):
  global count
  log=open(file_path,'r')
  C=r'\.'.join([r'\d{1,3}']*4)
  find=re.compile(C)
  count={}
  for i in log:
    for ip in find.findall(i):
      count[ip]=count.get(ip,1)+1
if __name__ == '__main__':
  print time.clock()
  num = 0
  mail_log(r'e:\MDaemon-20110329-all.log')
  R = count.items()
   for i in R:
     if i[1]>0: #Extract IPs with occurrences greater than 0 
      print i
      num +=1
   print  ' The quantity that meets the requirements: %s time-consuming (%s) ' %(num,time.clock())

The output is as follows:
