os.path.commonprefix (list) #返回list (multiple paths), the longest path common to all paths.
os.path.dirname (path) #返回文件路径
os.path.exists (path) #路径存在则返回True, path corruption returns false
os.path.lexists #路径存在则返回True, path corruption also returns true
os.path.expanduser (path) #把path中包含的 "~" and "~user" to the user directory
os.path.expandvars (path) #根据环境变量的值替换path中包含的 "$name" and "${name}"
os.path.getatime (Path) #返回最后一次进入此path的时间.
os.path.getmtime (Path) #返回在此path下最后一次修改的时间.
os.path.getctime (path) #返回path的大小
os.path.getsize (path) #返回文件大小, returns an error if the file does not exist
os.path.isabs (path) #判断是否为绝对路径
os.path.isfile (path) #判断路径是否为文件

Os.path.normpath (path) #规范path字符串形式
Os.path.realpath (path) #返回path的真实路径
Os.path.relpath (path[, start]) #从start开始计算相对路径
os.path.samefile (path1, path2) #判断目录或文件是否相同
os.path.sameopenfile (FP1, FP2) #判断fp1和fp2是否指向同一文件
Os.path.samestat (STAT1, STAT2) #判断stat tuple STAT1 and Stat2 point to the same file
os.path.split (path) #把路径分割成dirname和basename, returns a tuple
os.path.splitdrive (path) #一般用在windows下, returns a tuple of drive names and Paths
os.path.splitext (path) #分割路径, returns a tuple of pathname and file name extension
