前言

日常生活中常会遇到一些小任务，如果人工处理会很麻烦。

用python做些小脚本处理，能够提高不少效率。或者可以把python当工具使用，辅助提高一下办公效率。(比如我常拿python当计算器，计算和字符转换用)

以下总结下个人用到的一些python小脚本留作备忘。

打印16进制字符串

用途：通信报文中的hex数据不好看，可以打印为16进制的字符串显示出来。

#coding=utf-8
#name: myutil.py
def print_hex1(s,prev='0x'):
    for c in s:
        print '%s%02x' %(prev,ord(c)),
    print
def print_hex(s):
    for c in s:
        print '%02x' %(ord(c)),
    print
print 'myutil'

def print_hex3(s,prev='0x'):
    i = 0
    for c in s:
        print '%s%s,' %(prev,s[i:i+2]),
        i += 2
    print

文件合并

之前搞单片机时生成的hex应用程序文件不能直接刷到单片机里，还需要把iap程序合并成一个文件才能烧写到单片机。每次打包麻烦，做个脚本处理：

#path='C:\\Users\\test\\IAP_CZ_v204w.hex'
#file=open(path,'r')
#for ll in file.readlines()
#    print ll
#coding=gb18030
import time
import os
def prr():
    print 'file combination begin..'

path0=os.getcwd()
print path0
path=path0
#path1=path0
path2=path0
path+='\\IAP_CZ_v204w.hex'
#path1+='\\NC_armStaSystem.hex'
path2+='\\'
print path
s=raw_input('enter file path:')
path1=s
#path1+='\\NC_armStaSystem.hex'
print path1
s=raw_input('enter file name:')
path2+=s
path2+=time.strftime('_%y%m%d%H%M%S')
path2+='.hex'
print path2
prr()
try:
    f1=open(path,'r')
    count=0
    for l in f1.readlines():
    #    print l
        count+=1
    #print count
    f1.close()
    f1=open(path,'r')
    f2=open(path1,'r')
    f3=open(path2,'w')
    while(count>1):
        l=f1.readline()
    #   print l
        f3.write(l)
        count-=1
    #   print count
    f3.flush()
    for l in f2.readlines():
        f3.write(l)
    f3.flush()
    f3.close()
    print 'combination success!'
except Exception,ex:
    print 'excettion occured!'
    print ex
    s=raw_input('press any key to continue...')
finally:
    f1.close()
    f2.close()
    s=raw_input('press any key to continue...')

多线程下载图集

网上好看的动漫图集，如果手工下载太费时了。简单分析下网页地址规律，写个多线程脚本搞定。

远程读卡器server端

很早之前做过一个远程读卡器工具，原理就是在现场客服电脑上装个python做的tcpserver服务端，操控现场的读卡器。在公司内部做个客户端连接过去，这样实现在公司调试现场的卡片业务。

这个就是服务端工具的实现：

如果连接不到远程，会sleep 36s，最多尝试200(即两小时)
@usage:
./rtcp.py stream1 stream2
stream为：l:port或c:host:port
l:port表示监听指定的本地端口
c:host:port表示监听远程指定的端口
