各位用户为了找寻关于Python遍历目录的4种方法实例介绍的资料费劲了很多周折。这里教程网为您整理了关于Python遍历目录的4种方法实例介绍的相关资料，仅供查阅，以下为您介绍关于Python遍历目录的4种方法实例介绍的详细内容
1.os.popen运行shell列表命令
代码如下: def traverseDirByShell(path): for f in os.popen('ls ' + path): print f.strip()2.利用glob模块
glob.glob(path)返回带目录的文件名.通配符和shell相似.path不能包含shell变量.
代码如下: def traverseDirByGlob(path): path = os.path.expanduser(path) for f in glob(path + '/*'): print f.strip()3.利用os.listdir(推荐)
该方法返回不带根目录的文件名或子目录名
代码如下: def traverseDirByListdir(path): path = os.path.expanduser(path) for f in os.listdir(path): print f.strip()4.利用os.walk(推荐)
返回一个包含3个项目的元组:当前目录名称,子目录名称,子文件名称
代码如下: def traverseDirByOSWalk(path): path = os.path.expanduser(path) for (dirname, subdir, subfile) in os.walk(path): #print('dirname is %s, subdir is %s, subfile is %s' % (dirname, subdir, subfile)) print('[' + dirname + ']') for f in subfile: print(os.path.join(dirname, f))整合代码:
代码如下:#!/usr/bin/python import os from glob import glob
def printSeparator(func): def deco(path): print("call method %s, result is:" % func.__name__) print("-" * 40) func(path) print("=" * 40) return deco
@printSeparator def traverseDirByShell(path): for f in os.popen('ls ' + path): print f.strip()
@printSeparator def traverseDirByGlob(path): path = os.path.expanduser(path) for f in glob(path + '/*'): print f.strip()
@printSeparator def traverseDirByListdir(path): path = os.path.expanduser(path) for f in os.listdir(path): print f.strip()
@printSeparator def traverseDirByOSWalk(path): path = os.path.expanduser(path) for (dirname, subdir, subfile) in os.walk(path): #print('dirname is %s, subdir is %s, subfile is %s' % (dirname, subdir, subfile)) print('[' + dirname + ']') for f in subfile: print(os.path.join(dirname, f))
if __name__ == '__main__': path = r'~/src/py' traverseDirByGlob(path)
traverseDirByGlob(path)
traverseDirByListdir(path)
traverseDirByOSWalk(path)
