Python 如何查找在特定日期ping的IP数？

我有一个python文件，我将日志文件和url传递给代码。输出文件包含IP地址访问URL的次数

#!/usr/bin/env python
# 
# Counts the IP addresses of a log file.
# 
# Assumption: the IP address is logged in the first column.
# Example line: 117.195.185.130 - - [06/Mar/2012:00:00:00 -0800] \
#    "GET /mysidebars/newtab.html HTTP/1.1" 404 0 - -
#

grep、cut、sort和uniq有什么问题

grep "\[07/Mar/2012" logfile.txt | cut -d " " -f 1 | sort | uniq
