Python 操作文件及目录

由 ziDANe 撰写 | 2010/02/11 15:01 发表在 Learning Python | 评论 (0)

一、python 文件操作

1.import glob 目录操作

查看目录内容：
filelist=glob.glob(‘*.*’)
filelist=glob.glob(‘c:\*’)
查看指定类型的文件：
filelist=glob.glob(‘c:\*.sys’)
为了显示一个目录中的全部文件，可以使用如下所示的os.listdir函数：


　 files = os.listdir(r’C:\hpl\scripting\src\py\intro’) #适用于 Windows
　 files = os.listdir(’/home/hpl/scripting/src/py/intro’) # 适用于Unix
    files = os.listdir("d:\python26")
    files=os.listdir("c:\\")
# 跨平台版本:
　　files = os.listdir(os.path.join(os.environ[’scripting’],
　　’src’, ’py’, ’intro’))
　　files = os.listdir(os.curdir) # 当前目录中的所有文件
　　files = glob.glob(’*’) + glob.glob(’.*’)

二、测试文件类型

python 批量图片重命名脚本

由 ziDANe 撰写 | 2010/02/08 23:24 发表在 Python Code | 评论 (1)

经常从网上保存图片的时候都是随手另存为，保存图片的目录凌乱不堪。
写了个脚本按照文件保存的顺序进行排序，并按照保存的时间顺序进行重命名，这样图片基本可以按照分类保存，即一类的图片是连续保存的。
