So cute are you python 17

1.python 实现linux ls 命令:

#!/bin/evn python
#coding:utf-8
#FileName:ls.py
#Function:Show the files or directories on a path.
#history:16-11-2013
import os
path=raw_input("Pleace input the path you want to check._")
print os.listdir(path)

2.python 实现文件的遍历1:

#!/bin/evn python
#FileName:walk.py
#Function:Show the files or directories on a path.
#history:16-11-2013
import os
export =[]
path=raw_input('Pleace input the path you wanna to check._')
for root,dirs,files in os.walk(path):
    export.append("\n%s; %s; %s"%(root,dirs,files))
open('myc.txt','w').write(''.join(export))

3.python 实现文件的遍历2:

#!/bin/evn python
#FileName:walk_1.py
#Function:Show the files or directories on a path.
#history:16-11-2013
import os,sys
def cdfiles(cdpath,cdfiles):
    export =[]
    if(len(cdpath)== 0):
        cdpath=raw_input('Pleace input the path you wanna to check._')
    for root,dirs,files in os.walk(cdpath):
        export.append("\n%s; %s; %s"%(root,dirs,files))
    open('myc.txt','w').write(''.join(export))
if __name__=='__main__':
    #print sys.argv
    if(sys.argv[ 1]=='-e'):
        files='myc.txt'
        cdfiles(sys.argv[ 1],files)
    else:
        print '''Usage:_walk_1.py:
               python walk_1.py -e /var/ --
               store the information into myc.txt.'''

4.python cmd 的使用:

#!/bin/evn python
#coding:utf-8
#FileName:refactoring.py
#Function:Show how to refactoring code.
#history:16-11-2013
import sys,cmd,os
class PyCDC(cmd.Cmd):
    def __init__(self,):
        cmd.Cmd.__init__(self)
    def cd_ls(self,filename,path):
        export =[]
        if path=="":path=raw_input('请输入搜索的路径_')
        for root,dirs,files in os.walk(path):
            export.append("\n%s; %s; %s"%(root,dirs,files))
        open(filename,'w').write(''.join(export))
    def help_EOF(self):
        print "退出程序"
    def do_EOF(self,line):
        sys.exit()
    def help_Walk(self):
        print '扫描文件内容 写入 *.txt'
    def do_walk(self,filename):
        spath=""
        if filename=="":
            filename=raw_input("输入导出文件的*.txt 文件名::")
        if spath=="":
            spath=raw_input("请输入要搜索的路径::")
        export =[]
        for root,dirs,files in os.walk(spath):
            export.append("\n%s; %s; %s"%(root,dirs,files))
        open(filename,'w').write(''.join(export))
        print '扫描的内容 存放于 %s'%filename
    def help_dir(self):
        print '指定保存路径.'
    def do_dir(self,path):
        if path=="":path=raw_input("Pleace input the path you wanna to search.")
        print ""
    def help_find(self):
        print "搜索关键字."
    def do_find(self,keyword):
        if keyword=="":keyword=raw_input("输入搜索关键字:_")
        print "搜索关键字 %s"%keyword
 
if __name__=='__main__':
    cdc=PyCDC()
    cdc.cmdloop()

效果图:

$ python refactoring.py 
(Cmd) walk
输入导出文件的*.txt 文件名::myc.txt
请输入要搜索的路径::/var/www/sql
扫描的内容 存放于 myc.txt
(Cmd) help
