小脚本

1.找出某目录下所有以‘.log’结尾的文件并删除

import os
print(os.getcwd())
os.chdir(r'文件所在目录')
li = os.listdir()#列出该目录下的所有文件
for i in li:
    if i.endswith('.log'):  #找出所有以.log结尾的文件并删除
        os.remove(i)

 2.利用paramiko批量远程登录服务器执行命令，并返回结果

import  commands
import subprocess
import paramiko
import time
host_lists=(
('192.168.1.12'),
('192.168.1.240'),
('172.168.96.3'),
('192.168.1.12'),
('172.168.96.3'),
('192.68.23.25'),
('10.236.53.69'),
('11.23.36.33'),
)


def getServerInfo(host,user,password,services):
    conn=paramiko.SSHClient()
    conn.load_system_host_keys()
    conn.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    conn.connect(hostname=host,port=22,username=user,password=password,allow_agent=False,look_for_keys=False)
    stdin,stdout,stderr=conn.exec_command("ps aux|awk '{print $3,$4,$5,$6,$11}'|grep %s" % services,timeout=5)#要执行的命令
    info=stdout.read()  # 在python3中，获取的info值是字节型（b'dsfdfffd'），要decode一下
       info = info.decode('utf-8')
       conn.close()
    return info
def ping_test(host):
    p =  commands.getoutput("ping "+host+" -w 1|wc -l") #指定ping一秒
    if p =='6':   #如果能ping通
        info=getServerInfo(host,'root','111111','pick')
        info_list=info.split()
        print "%s		%s		%s		%s		%s		%s	"%(host,info_list[0],info_list[1],info_list[2],info_list[3],info_list[4]),
        with open("yes.log","a+") as f:
            f.write(host+'
')
    elif p == '5': #如果不能ping通
        print  "%s		NO		NO		NO		NO		NO	"% (host),
        with open("no.log","a+") as f_no:
            f_no.write(host+'
')
def out_info():
     now1 = time.time()
     ping_test(host)
     now2 = time.time()
     now3 = now2 - now1
     print "	",now3
if __name__ == '__main__':
    print"ip                     %CPU            %MEM             VSZ             RSS            services         time_use(s)"

    for host in host_lists:
        try:
            out_info()
        except:
            print host,"      NO_ssh"
            with open("no_ssh.log","a+") as f_except:
                f_except.write(host+'
')

 3.paramiko/client.py

第220行设置网络不通超时时间

4.设置输出颜色

格式：033[显示方式;前景色;背景色m
 
说明：
前景色            背景色           颜色
---------------------------------------
30                40              黑色
31                41              红色
32                42              绿色
33                43              黃色
34                44              蓝色
35                45              紫红色
36                46              青蓝色
37                47              白色
显示方式           意义
-------------------------
0                终端默认设置
1                高亮显示
4                使用下划线
5                闪烁
7                反白显示
8                不可见
 
例子：
033[1;31;40m    <!--1-高亮显示 31-前景色红色  40-背景色黑色-->
033[0m          <!--采用终端默认设置，即取消颜色设置-->   

• 备注：
  • 33[1;31;40m： 代表接下来输出内容为：高亮显示，前景色为红色，背景色被黑色。
  • 33[0m：代表接下来的输入内容为终端默认设置，也就是取消之前的颜色设置，如果没有这个，接下来的输出，都是上面的设置。
• 例子：

password = raw_input('请输入用户密码，如果不设置，33[5;33;40m请回车!33[0m。默认密码为: NewPassWord2016)')

• • 我的设置是，闪烁、前景色为黄色，背景色为黑色。输出的效果是：”请回车“  这三个字一直在闪烁，且字体为黄色，背景色为黑色。

5.获取当前局域网内的所有在用ip

##python 2.7
import platform
import sys
import os
import time
import thread


def get_os():
    os = platform.system()
    if os == "Windows":
        return "n"
    else:
        return "c"


def ping_ip(ip_str):
    cmd = ["ping", "-{op}".format(op=get_os()),"1", ip_str]
    output = os.popen(" ".join(cmd)).readlines()

    flag = False
    for line in list(output):
        if not line:
            continue
        if str(line).upper().find("TTL") >= 0:
            flag = True
            break
    if flag:
        print "ip: %s is useing ***" % ip_str


def find_ip(ip_prefix):
    for i in range(1, 256):
        ip = '%s.%s' % (ip_prefix, i)
        thread.start_new_thread(ping_ip, (ip,))
        time.sleep(0.3)


if __name__ == "__main__":
    commandargs = raw_input( "Enter start IP  [For example:192.168.1.1] >>>")
    print "start time %s" % time.ctime()
    commandargs = str(commandargs)
    args = "".join(commandargs)
    ip_prefix = '.'.join(args.split('.')[:-1])
    find_ip(ip_prefix)
    print "end time %s" % time.ctime()

 6.根据ip地址获取当前位置信息（调用百度地图接口）

基于python3.5

from urllib import request
import gevent,time
import json
from gevent import monkey
monkey.patch_all() #把当前程序的所有的io操作单独的做上标记,这样gevent就可以识别到io操作了

def f(url):
    print('GET: %s' % url)
    resp = request.urlopen(url)
    data = resp.read().decode()
    with open('ip.txt','w') as f:
        f.write(data)
    with open("ip.txt","r") as f:
        for i in f:        #注意，json反序列化的时候要迭代才可以，否则报错
            c = json.loads(i)
        print(type(c),c)
        print(c["address"])
    print('%d bytes received from %s.' % (len(data), url))

async_time_start = time.time()
gevent.joinall([
#     gevent.spawn(f, 'https://www.python.org/'),
#     gevent.spawn(f, 'https://www.yahoo.com/'),
#     gevent.spawn(f, 'https://github.com/'),
      gevent.spawn(f, 'http://api.map.baidu.com/location/ip?ak=NKrVZ3qLBjSG47KKMjIsfNW3CSwrp4GT&coor=bd09ll',)
])
print("异步cost",time.time() - async_time_start)

输出：
GET: http://api.map.baidu.com/location/ip?ak=NKrVZ3qLBjSG47KKMjIsfNW3CSwrp4GT&coor=bd09ll
<class 'dict'> {'address': 'CN|山东|济宁|None|UNICOM|0|0', 'content': {'point': {'x': '116.60079762', 'y': '35.40212166'}, 'address': '山东省济宁市', 'address_detail': {'district': '', 'street_number': '', 'province': '山东省', 'city_code': 286, 'city': '济宁市', 'street': ''}}, 'status': 0}
CN|山东|济宁|None|UNICOM|0|0
317 bytes received from http://api.map.baidu.com/location/ip?ak=NKrVZ3qLBjSG47KKMjIsfNW3CSwrp4GT&coor=bd09ll.
异步cost 0.062041282653808594

基于python2.7

# encoding=utf8

import json
import urllib2
import httplib
#调用百度地图接口
url = 'http://api.map.baidu.com/location/ip?ak=NKrVZ3qLBjSG47KKMjIsfNW3CSwrp4GT&coor=bd09ll'
temp = urllib2.urlopen(url)
hjson = json.loads(temp.read())
#print hjson
province = hjson['content']['address_detail']['province']
city = hjson['content']['address_detail']['city']
city_code = hjson['content']['address_detail']['city_code']
address = hjson['content']['address']
point = hjson['content']['point']
aa = hjson['address']
print "城市代码：",city_code
print "地址：",address
print "纬度：",point['y']
print '经度:',point['x']
print "详细（包含地址及运营商信息）：",aa

 7.进度条

#!usr/bin/env/python
# -*- coding:utf-8 -*-
# from  wangteng
import time
import sys
for i in range(101):
    sys.stdout.write('
')
    sys.stdout.write("%s%% |%s" %(int(i%101), int(i%101)*'#'))
    sys.stdout.flush()
    time.sleep(0.5)

sys.stdout.write('
')

#!usr/bin/env/python
# -*- coding:utf-8 -*-
# from  wangteng
import time
import sys
for i in range(101):
    sys.stdout.write('
')
    sys.stdout.write("%s%% |%s" %(int(i%101), int(i%101)*'#'))
    sys.stdout.flush()
    time.sleep(0.5)

sys.stdout.write('
')

可以根据以下代码修改，将分子分母都修改为变量

zi = 67
fu = 103
a = zi/fu*100
a = int(a)
print(a*'#')
a = str(a)
print(a[:5],'%')

 8.mysql表插入数据时自动添加插入时间，只需要在原表上再加一个字段即可TIMESTAMP

    ALTER TABLE t2 ADD nowtime TIMESTAMP default CURRENT_TIMESTAMP;

 9.html每5秒自动刷新页面

<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <META HTTP-EQUIV="Refresh" CONTENT="5">
</head>

10.html修改时间格式

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <META HTTP-EQUIV="Refresh" CONTENT="5">
</head>
<body>
主要是script代码
<script>
function date2str(x,y) {
    var z = {M:x.getMonth()+1,d:x.getDate(),h:x.getHours(),m:x.getMinutes(),s:x.getSeconds()};
    y = y.replace(/(M+|d+|h+|m+|s+)/g,function(v) {return ((v.length>1?"0":"")+eval('z.'+v.slice(-1))).slice(-2)});
    return y.replace(/(y+)/g,function(v) {return x.getFullYear().toString().slice(-v.length)});
}
var d = new Date('Mon Feb 06 2017 16:21:44');自定义一个时间
alert(date2str(d,"yyyy-MM-dd hh:mm:ss"));
alert(date2str(d,"yyyy-M-d h:m:s"));
</script>
</body>
</html>
