在日常的工作中,python用到的概率还是比较的大的,那么,我们应该怎么去学习关于python的知识呢?平常用到的脚本都是有哪些呢?下面小编给大家详细介绍下。
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。
