Python - 文件夾中所有文件的平均長度函數

Question

我有一個函數可以查找平均字符串長度。現在我試圖編寫一個函數來遍歷並觸摸目錄中的每個txt文件，並返回文件的最高均值。我現在所擁有的東西似乎沒有正確穿越。 Pleeease的幫助。謝謝。

from __future__ import print_function 
import os 

def mean_length(file path): 
    length = 0.0 
    line_num = 0 
    with open(filepath) as f: 
     for line in f: 
      if line.strip(): 
       length += len(line.strip()) 
       line_num += 1 
    return length/line_num 

def highest_mean(): 
    max_mean = 0 
    max_name = "" 
    filepath = open("Desktop/Textfiles/moby.txt") 
    for root, dirs, files in os.walk("Desktop/Textfiles"): 
     for filename in files: 
      if filename.endswith('.txt'): 
       filepath = os.path.join(root, filename) 
       if mean_length(filepath) > max_mean: 
        max_name = filename 
        max_mean = mean_length(filepath) 
      return max_name

我認爲你需要經過的所有文件，以獲得一個最高的平均值，可能與另外兩個變量：

def mean_length(filepath): 
    length = 0.0 
    line_num = 0 
    with open(filepath) as f: 
     for line in f: 
      if line.strip(): 
       length += len(line.strip()) 
       line_num += 1 
    return length/line_num 

def highest_mean(): 
    max_mean = 0 
    max_name = "" 
    for root, dirs, files in os.walk("Desktop/Textfiles"): 
     for filename in files: 
      if filename.endswith('.txt'): 
       filepath = os.path.join(root, filename) 
       m_length = mean_length(filepath) 
       if m_length > max_mean: 
        max_name = filename 
        max_mean = m_length 
    return max_name
