磁盘使用情况root@ubuntu:/data/server/spider/面试题# cat 02check_disk.py
import time
import os
new_time = time.strftime('%Y-%m-%d')
print(new_time)
disk_status = os.popen('df -h').readlines()
str1 =''.join(disk_status)
with open(new_time+'.log','w') as f:
f.write('%s' % str1)
f.flush()
f.close()

四、生成磁盘使用情况的日志文件
#!/usr/bin/env python
#!coding=utf-8
import time
import os
new_time = time.strftime('%Y-%m-%d')
disk_status = os.popen('df -h').readlines()
str1 = ''.join(disk_status)
f = file(new_time+'.log','w')
f.write('%s' % str1)
f.flush()
f.close()
五、统计出每个IP的访问量有多少？（从日志文件中查找）
#!/usr/bin/env python
#!coding=utf-8
list = []
f = file('/tmp/1.log')
str1 = f.readlines()
f.close()
for i in str1:
ip = i.split()
list.append(ip)
list_num = set(list)
for j in list_num:
num = list.count(j)
print '%s : %s' %(j,num)
