本文实例讲述了python对文件目录的操作方法。分享给大家供大家参考,具体如下:
python 可以很方便的对文件进行打开,读写操作,删除操作,也可以很方便的对文件夹进行遍历操作。总体说来,有如下几个方面:
1. python 遍历文件目录,当然可以递归
2. python 删除文件
3. python 对文件进行重命名操作
4. python 创建文件夹 (多个层级创建)
5. python 删除文件夹 (多个层级删除)
6. python 移动文件
7. python 查找文件
8. 得到文件夹的大小
下面的代码是我在用python 做一个网盘服务端的时候用到的一些方法,记录下来,以供以后参考.
#coding:utf-8 import StringIO import json import os import time import glob import shutil DATETIMEFORMATER='%Y-%m-%d %X' #only for windows RECYCLED_FOLDER_NAME='Recycled' def dateformat(datetime): '''return GMT TIME,need to change to LOCAL TIME''' return time.strftime( DATETIMEFORMATER,time.gmtime(datetime) ) def filesizeformat(size): ''' Convert file size to string ''' KBSIZE=1024.00 strSize='0 Byte' if (size < KBSIZE): strSize = '%.2f Byte' % (size) elif (size >= KBSIZE and size < KBSIZE**2): strSize = '%.2f K' % (size / KBSIZE) elif (size >= KBSIZE**2 and size < KBSIZE**3): strSize = '%.2f M' % (size / KBSIZE / KBSIZE) elif (size >= KBSIZE**3): strSize = '%.2f G' % (size / KBSIZE / KBSIZE / KBSIZE) return strSize def listdir(path): if os.path.isfile(path): return '[]' allFiles=os.listdir(path) retlist=[] for cfile in allFiles: fileinfo={} filepath=(path+os.path.sep+cfile).replace("\\","/") if cfile==RECYCLED_FOLDER_NAME: continue if os.path.isdir(filepath): fileinfo['isfile'] = '0' fileinfo['size'] = getfoldersize(filepath) else: fileinfo['isfile'] = '1' fileinfo['size'] = os.path.getsize(filepath) fileinfo['name'] = cfile fileinfo['lastvisittime'] = dateformat( os.path.getatime(filepath) ) fileinfo['createtime'] = dateformat( os.path.getctime(filepath) ) fileinfo['lastmodifytime'] = dateformat( os.path.getmtime(filepath) ) retlist.append(fileinfo) retStr=json.dumps(retlist,encoding='utf-8') return retStr def deletefile(path): if os.path.exists(path): os.remove(path) def rename(old,new): if os.path.exists(old): os.rename(old, new) def checkoutfile(path): pass def checkinfile(path): pass def lockfile(path): pass def unlockfile(path): pass def createfolder(path): if not os.path.exists(path): os.mkdir(path) def createfolders(path): if not os.path.exists(path): os.makedirs(path); def deletefolder(path): if os.path.isdir(path): os.rmdir(path) def retreeExceptionHandler(fun,path,excinfo): pass def deletefolders(path): # if os.path.isdir(path): # os.removedirs(path) shutil.rmtree(path,ignore_errors=False,onerror=retreeExceptionHandler) def movefile(old,new): shutil.move(old, new) def getfoldersize(path): size = 0 for root, dirs, files in os.walk(path): size += sum([os.path.getsize(os.path.join(root, name)) for name in files]) return size def searchfile(path,ext): returnList=glob.glob1(path, ext) return returnList if __name__=='__main__': listdir('c:/vDriver') #searchfile('c:/vDriver','*.log')
上面的代码,根据方法的命名,就可以知道 python 操作文件以及文件夹的各种方法。
希望本文所述对大家Python程序设计有所帮助。
