Python Action folder

Python's operations summary of folders for easy access to

1. Traverse the specified directory to display all file names under the directory

#-*-coding:utf-8-*-import osdef fileinfolder (filepath):    pathdir =  os.listdir (filepath)  # Get all files under the filepath folder file    = [] for    Alldir in pathdir: Child        = Os.path.join ('%s\\%s '% (filepath, alldir)) C6/>files.append (Child.decode (' GBK '))  #. Decode (' GBK ') is a solution to the Chinese display garbled problem        # print Child        # if Os.path.isdir ( Child):        #     Print Child        #     Simplepath = os.path.split (Child)        #     Print Simplepath    return Filesfilepath = "C:\\files" Print  fileinfolder (filepath) output: [u ' c:\\files\\a.txt ', U ' c:\\files\\b.txt ', U ' C:\\files\\c ']

　　

2. Traverse all files of the folder and its subfolders to get a list of the files

#-*-coding:utf-8-*-import osdef getfilelist (filepath):    filelist =  os.listdir (filepath)  # Get all files under the filepath folder file    = [] for    I in range (len (filelist)): Child        = Os.path.join ('%s\\%s '% (filepath, Filelist[i])        if Os.path.isdir (child):            files.extend (getfilelist (child))        else:            files.append ( Child)    return filesfilepath = "C:\\files" Print getfilelist (filepath) output: [' c:\\files\\a.txt ', ' c:\\files\\b.txt ' , ' C:\\files\\c\\d.txt ', ' c:\\files\\c\\e.txt ', ' c:\\files\\c\\f\\g.txt ']

　　

3. Python traverses the sub-file and all subfolder output strings

#-*-coding:utf-8-*-import osdef getfilelist (filepath, tabnum=1):    Simplepath = os.path.split (filepath) [1]    RETURNSTR = simplepath+ "directory <>" + "\ n"    returndirstr = ""    returnfilestr = ""    filelist = Os.listdir ( filepath) for    num in range (len (filelist)):        Filename=filelist[num]        if Os.path.isdir (filepath+ "/" + FileName):            returndirstr + = "\ T" *tabnum+getfilelist (filepath+ "/" +filename, tabnum+1)        else:            Returnfilestr + = "\ t" *tabnum+filename+ "\ n"    returnstr + = returnfilestr+returndirstr    return returnstr+ "\ T" * tabnum+ "</>\n" filepath = "c:\\files" f = open ("Test.xml", "w+") F.writelines (Getfilelist (filepath)) F.close ()

　　

4. Batch renaming of documents

#-*-coding:utf-8-*-import osdef filesrename (filepath):    filelist =  os.listdir (filepath)  # Get all files under the filepath folder file    = [] for    I in range (len (filelist)): Child        = Os.path.join ('%s\\%s '% (filepath, Filelist[i])        if Os.path.isdir (child):            continue        Else:            newName = Os.path.join ('%s\\%s '% (filepath, STR (i) + "_" + Filelist[i]))            print newName            os.rename (Child, newName) filepath = "C:\\files2" Filesrename ( FilePath
