在日常的工作中，python用到的概率還是比較的大的，那么，我們應(yīng)該怎么去學(xué)習(xí)關(guān)于python的知識(shí)呢？平常用到的腳本都是有哪些呢？下面小編給大家詳細(xì)介紹下。
前言
日常生活中常會(huì)遇到一些小任務(wù)，如果人工處理會(huì)很麻煩。
用python做些小腳本處理，能夠提高不少效率?；蛘呖梢园裵ython當(dāng)工具使用，輔助提高一下辦公效率。(比如我常拿python當(dāng)計(jì)算器，計(jì)算和字符轉(zhuǎn)換用)
以下總結(jié)下個(gè)人用到的一些python小腳本留作備忘。
打印16進(jìn)制字符串
用途：通信報(bào)文中的hex數(shù)據(jù)不好看，可以打印為16進(jìn)制的字符串顯示出來(lái)。
#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
之前搞單片機(jī)時(shí)生成的hex應(yīng)用程序文件不能直接刷到單片機(jī)里，還需要把iap程序合并成一個(gè)文件才能燒寫(xiě)到單片機(jī)。每次打包麻煩，做個(gè)腳本處理：
#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...')多線程下載圖集
網(wǎng)上好看的動(dòng)漫圖集，如果手工下載太費(fèi)時(shí)了。簡(jiǎn)單分析下網(wǎng)頁(yè)地址規(guī)律，寫(xiě)個(gè)多線程腳本搞定。

摘要：做這一領(lǐng)域的工作，有很多網(wǎng)站能夠起到輔助性的作用。再加上爬蟲(chóng)相對(duì)于其他熱門(mén)方向來(lái)說(shuō)，更容易學(xué)。也促使更多人會(huì)優(yōu)先選擇學(xué)習(xí)爬蟲(chóng)。能夠代替手工完成手工無(wú)法完成的測(cè)試任務(wù)，并且可以記錄相關(guān)數(shù)據(jù)及報(bào)告。 ...
摘要：簡(jiǎn)單介紹自帶庫(kù)，使用調(diào)試程序還是很方便的。比如下圖就是展示斷點(diǎn)進(jìn)入到內(nèi)部之后，打印的參數(shù)，打印某個(gè)變量退出調(diào)試，直接退出調(diào)試或者使用的方式退出最后說(shuō)一句上面展示的使用調(diào)試的過(guò)程其實(shí)是很簡(jiǎn)單的，文章中主要通過(guò)截圖展示運(yùn)行的效果。 簡(jiǎn)單介紹 Python自帶 Pdb庫(kù)，使用 Pdb調(diào)試 Python程序還是很方便的。但是遠(yuǎn)程調(diào)試、多線程，Pdb是搞不定的 本文參考的相關(guān)文章如下： 《指針...
摘要：內(nèi)存池機(jī)制提供了對(duì)內(nèi)存的垃圾收集機(jī)制，但是它將不用的內(nèi)存放到內(nèi)存池而不是返回給操作系統(tǒng)。為了加速的執(zhí)行效率，引入了一個(gè)內(nèi)存池機(jī)制，用于管理對(duì)小塊內(nèi)存的申請(qǐng)和釋放。 注：答案一般在網(wǎng)上都能夠找到。1.對(duì)if __name__ == main的理解陳述2.python是如何進(jìn)行內(nèi)存管理的？3.請(qǐng)寫(xiě)出一段Python代碼實(shí)現(xiàn)刪除一個(gè)list里面的重復(fù)元素4.Python里面如何拷貝一個(gè)對(duì)象？...
