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：
