Py指令碼:轉換兩個檔案名稱

自己寫的一個簡單的交換兩個檔案（夾）的py指令碼，一開始本打算用shell寫的，後來趕腳自己的shell還是比較菜，不如python來的利索，於是py了。

代碼如下：

#!/usr/bin/env python# coding=utf-8# author:andrewallanwallace@gmail.com'''This simple script is written for easily swap two files or two folders.'''def swap(origin, dest, temp):    '''    Swap files     mv origin temp    mv dest origin    mv temp dest    '''    from os import system    origin2Temp = 'mv -f -v %s %s'%(origin, temp)    system(origin2Temp)        dest2Origin = 'mv -f -v %s %s'%(dest, origin)    system(dest2Origin)    temp2Dest = 'mv -f -v %s %s'%(temp, dest)    system(temp2Dest)def shouldSwap(origin, dest):    from os import path        originExists = path.exists(origin)    destExists = path.exists(dest)    if(not originExists or not destExists):        print 'Both the files should be existing %s existing State = %s ; %s existing State = %s'%(origin, str(originExists), dest, str(destExists))        return False         originIsDir = path.isdir(origin)    destIsDir = path.isdir(dest)    if (originIsDir != destIsDir):        print 'the two files should be the same type %s is dir = %s ;%s is dir = %s'%(origin, str(originIsDir), dest, str(destIsDir))        return False    return True        def main():    '''    Usage:swapf.py origin dest [temp]    '''    import sys    paramsSize = len(sys.argv)        origin = None    dest = None    temp = 'temp_backup.file'    if (paramsSize < 3):        print main.__doc__        return    origin = str(sys.argv[1])    dest = str(sys.argv[2])    if (paramsSize == 4):        temp = str(sys.argv[3])    if (shouldSwap(origin, dest)):        swap(origin, dest, temp)main()

使用方法

檔案：

swapf.py a.txt b.txt temp.txt

檔案夾

swapf.py folderA folderB tempFolder

第三個參數不需要添加也可以。
