python 檔案相關函數

os模組：

os.path.exists(path)        -->bool   #(path)檔案或者目錄存在os.path.abspath(path)    -->str      #(path)返迴文件或者目錄的絕對路徑# 下面幾個顧名思其義吧os.path.isfile(path)         -->boolos.path.isdir(path)         -->boolos.path.islink(path)        -->boolos.path.join(p_parent,p_sub) -->str  #返回新的path，父路徑+新路徑os.path.relpath(path[, start]) -->str   #返回相對路徑os.sep                   -->返回系統的分隔字元==java的File.seperatoros.path.getsize(path)  -->long  返迴文件的size#返回一個三元元組os.walk(dpath)(目錄abspath,[子目錄list],[子檔案list])

 readfile.py：

 

#/bin/pythonimport osfor p in os.walk("D:\prj\py\part11_file\pfiles"):print p

 目錄結構：D:\prj\py\part11_file

('D:\\prj\\py\\part11_file\\pfiles', ['dir1', 'dir2'], ['log.log', 'readfile.py', 'sometext.txt', 'stories.txt'])('D:\\prj\\py\\part11_file\\pfiles\\dir1', ['dir_par'], ['a.txt'])('D:\\prj\\py\\part11_file\\pfiles\\dir1\\dir_par', [], ['log.log'])('D:\\prj\\py\\part11_file\\pfiles\\dir2', [], ['readfile.py', 'stories.txt'])
