Some functions record python

This time it was mainly the record about some of the modules or functions of another experiment.

os module

the os.listdir () function can display all the information in the specified directory. 
     EG: the os.listdir (. " / " ) 
of course use Walk () 
OS (.stat; path) 
the os.path () to process the file path

os-file-dir file directory information

#coding=utf-8
import os
for root,dirs,files in os.walk('./');
    print root,dirs,files

The resulting file, the file name stored in the specified file inside

#coding=utf-8
import os
for root,dirs,files in os.walk('./'):
    open('test.txt','a').write("{}{}{}".format(root,dirs,files))

#下面另外两种写法
#coding=utf-8
import os
for root,dirs,files in os.walk('./'):
    export +="\n {}{}{}".format(root,dirs,files)
open('demo01.py','w').write(export)


#coding=utf-8
import os
export = []
for root,dirs,files in os.walk('./'):
    export.append("\n {}{}{}".format(root,dirs,files))
open('demo01.py','w').write(''.join(export))

File search the desired effect

pysoso.py Python - E mysoso.txt
 # directory contents recorded as mysoso.txt 
Python pysoso.py -e sos / mysoso.txt
 # saved in the directory contents to mysoso.txt sos directory 
python pysoso.py -d sos - k China refueling
 # information in the search sos directory, look for the file or directory with Chinese refueling words.

Want to achieve this effect it is necessary to write the contents of the file is functional.

#coding=utf-8
import os
def cdWalker(cdm,cdf):
    export = ""
    for root,dirs,file in os.walk(cdm):
        export += "\n{};{};{}".format(root,dirs,files)
    open(cdf,'w').write(export)
cdWalker('./','cd1.txt')
cdWalker('./','cd2.txt')

Join message

#coding=utf-8
import os,sys
print sys.argv
def cdWalker(cdm,cdf):
    export =　""
    for root,dirs,files in os.walk(cdm):
        export += "\n{};{};{}".format(root,dirs,files)
    open(cdf,'w').write(export)
#cdWalker('./','mysoso.txt')

Join determine if ...... else,

#coding=utf-8
import os,sys
CDM = './'
def cdWalker(cdm,cdf):
    export = ''
    for root,dirs,files in os.walk(cdm):
        export += '\n{};{};{}'.format(root,dirs,files)
    open(cdf,'w').write(export)
#cdWalker('./','mysos.txt')
if "-e" ==sys.argv[1]:
    cdWalker(CDM,sys.argv[2])
    print "Recording information {}" .Format (the sys.argv [2 ])
 the else :
      Print  '' ' PyC use: 
     Python pyc.py -e mysos.txt 
    # contents of the file is recorded as mysos.txt 
    ' ''
