I’d like to browse through the current folder and all its subfolders and get all the files with .htm|.html extensions. I have found out that it is possible to find out whether an object is a dir or file like this:
import os dirList = os.listdir("./") # current directory for dir in dirList: if os.path.isdir(dir) == True: # I don't know how to get into this dir and do the same thing here else: # I got file and i can regexp if it is .htm|html
and in the end, I would like to have all the files and their paths in an array. Is something like that possible?
You can use
os.walk() to recursively iterate through a directory and all its subdirectories:
for root, dirs, files in os.walk(path): for name in files: if name.endswith((".html", ".htm")): # whatever
To build a list of these names, you can use a list comprehension:
htmlfiles = [os.path.join(root, name) for root, dirs, files in os.walk(path) for name in files if name.endswith((".html", ".htm"))]
I had a similar thing to work on, and this is how I did it.
import os rootdir = os.getcwd() for subdir, dirs, files in os.walk(rootdir): for file in files: #print os.path.join(subdir, file) filepath = subdir + os.sep + file if filepath.endswith(".html"): print (filepath)
Hope this helps.
In python 3 you can use os.scandir():
for i in os.scandir(path): if i.is_file(): print('File: ' + i.path) elif i.is_dir(): print('Folder: ' + i.path)
newDirName = os.path.abspath(dir) to create a full directory path name for the subdirectory and then list its contents as you have done with the parent (i.e.
newDirList = os.listDir(newDirName))
You can create a separate method of your code snippet and call it recursively through the subdirectory structure. The first parameter is the directory pathname. This will change for each subdirectory.
This answer is based on the 3.1.1 version documentation of the Python Library. There is a good model example of this in action on page 228 of the Python 3.1.1 Library Reference (Chapter 10 – File and Directory Access).
Slightly altered version of Sven Marnach’s solution..
folder_location = 'C:SomeFolderName' file_list = create_file_list(folder_location)
def create_file_list(path): return_list = for filenames in os.walk(path): for file_list in filenames: for file_name in file_list: if file_name.endswith((".txt")): return_list.append(file_name) return return_list
from tkinter import * import os root = Tk() file = filedialog.askdirectory() changed_dir = os.listdir(file) print(changed_dir) root.mainloop()
