dizin başına python başına dosya basma sayısı

Question

Bu konuyla ilgili birkaç soru buldum, ancak gördüğüm sorunu gideren hiçbiri yok. Önceden özür dilerim python için yeniyim. Ne yapmaya çalışıyorum somedir altındaki her dizindeki dosyaların sayısını ise/bu yüzden böyle bir şey alacağı:

from os import listdir 
from os.path import isfile, isdir 

def walk(p): 
    for file in listdir(p): 
    if isfile(file): 
     print("File: " + file) 
    elif isdir(file): 
     print("Dir: " + file) 
     walk(file) 
    else: 
     print("Unknown: " + file) 

path = raw_input('Enter path to search') 
walk(path) 

: Ben bu olurdu yapabileceğim kanıtlamak için en kolay yolu düşünce

dir-a: 13 
dir-b: 6 
dir-c: 21 

Ancak, ilk yineleme beklendiği gibi çalışan tek örnektir. Dosyanın tam yolunu os.path.abspath ile eklemeyi ve yinelemeli aramalarda olduğu gibi, dosyanın ilk yinelemede aynı olduğundan emin olmak için birkaç yolu daha denedim. type(file) ile yazdım ve 'str' ve yol + dosya adı doğruysa ve yukarıdaki program hala beklenen sonuçları üretmek için başarısız olsa bile. Böyle bir dizin yapısı hakkında Örneğin:

dir-a/ 
    file-a.1 
    file-a.2 
    dir-b/ 
      file-b.1 
      file-b.2 
    file-a.3 

ben beklenebilir:

File: file-a.1 
File: file-a.2 
Dir: dir-b 
File: file-b.1 
File: file-b.2 
File: file-a.3 

ama olsun:

File: file-a.1 
File: file-a.2 
Dir: dir-b 
Unknown: file-b.1 
Unknown: file-b.2 
File: file-a.3 

Yani temelde tüm dosyalar üzerinde dosya veya dirs olarak tanımlanan sakın özyinelemeli çağrılar. listdir, isfile ve isdir'daki belgelere baktım ve yine de mantıklı değil. Aynı davranışta python 2.7.5 ve 3.4.0 ile çalıştım. Herhangi bir yardım takdir edilir.

Answer 1

Mutlak yol olayı hakkında haklısınız. Sadece walk

from os import listdir 
from os.path import isfile, isdir, join 

def walk(p): 
    for item in listdir(p): 
    item = join(p, item) 
    if isfile(item): 
     print("File: " + item) 
    elif isdir(item): 
     print("Dir: " + item) 
     walk(item) 
    else: 
     print("Unknown: " + item) 

path = raw_input('Enter path to search') 
walk(path) 

Çıktı (Not geçirilen değişken üzerinde listdir içeriğini katılarak olsa yolunu kendiniz oluşturabilirsiniz: hataları sonunda o alır bu yüzden zaman bu kutuyu kökü yok neden /root için bu çöküyor ama Python dilinde kabuk komutları çalıştırabilir

Enter path to search/

Kabuğu'nda aşağıdaki komutu bir dizindeki dosya sayısını listeler:

ls -1 targetdir | wc -l 

Answer 3

Alternatif bir yol standart kütüphaneden yürüyüş kullanarak:

import os 
from collections import defaultdict 

file_counter = defaultdict(list) 

for root, dirs, files in os.walk("/tmp"): 
    file_counter[root] += files 


for k,v in file_counter.items(): 
    print(k, len(v))

Ama dezavantajı, tüm dosya adlarının ve yönlerinin açıklamasını saklayabilmesidir. Bu pahalı olabilir, büyük dosya sistemlerini geçmeyi planlıyorsunuz.
