"Python" Python reads all files under a folder __python

Os.listdir (path) is a list of the names of the files that are obtained under the path path.     Open (path) is the opening of a file.         ITER is the Python iterator. So read all the files under a folder as follows:

Import os
path = "D:/python34/news" #文件夹目录
files= os.listdir (path) #得到文件夹下的所有文件名称
s = [] for
file in file S: #遍历文件夹
     if not os.path.isdir (file): #判断是否是文件夹, is not a folder open
          f = open (path+ "/" +file); #打开文件
          iter_f = iter (f); Create an iterator
          str = "" For
          lines in Iter_f: #遍历文件, row by row, read text
              str = str + line
          s.append (str) #每个文件的文本存到list中
Print (s) #打印结果

You can also define the traversal of a folder as a function, and iterate over it if it is a folder. Then read all the files in the folder (including the files in the folder)
