python获取一个目录下的文件以及子文件中的文件
Python获取文件夹下的文件和子文件夹
这里使用os.walk函数
关于函数该函数的介绍如下
os.walk(top, topdown=Ture, οnerrοr=None, followlinks=False)参数：
- top – 根目录下的每一个文件夹(包含它自己), 产生3-元组 (dirpath, dirnames, filenames)【文件夹路径, 文件夹名字, 文件名】
- topdown –可选，为True或者没有指定, 一个目录的的3-元组将比它的任何子文件夹的3-元组先产生 (目录自上而下)。如果topdown为 False, 一个目录的3-元组将比它的任何子文件夹的3-元组后产生 (目录自下而上)
- onerror – 可选，是一个函数; 它调用时有一个参数, 一个OSError实例。报告这错误后，继续walk,或者抛出exception终止walk
- followlinks – 设置为 true，则通过软链接访问目录。
函数执行之后得到一个三元tupple（dirpath， dirnames， filenams。
dirpath：string，是当前目录的路径；
dirnames：list， 是当前路径下所有的子文件夹名字；
filenames：list， 是当前路径下所有的非目录子文件的名字。
要获取完整的路径，dirnames和filenames是不包含路径信息的，可以使用
os.path.join(dirpath, dirnames)获得文件的完整路径。
下面为示例：
可以看出实现了递归解析，其中对于文件夹的输出中先输出的是底层的文件夹，最后是顶层文件夹。
for root, dirs, files in os.walk('/S1/LCWM/jinhq/program/Untitled Folder', topdown=False):
for name in files:
path = os.path.join(root, name)
print(root)
print(name)
print(path)
break输出为：
