python - 为什么 os.path.getsize() 在 python 中抛出错误？

Question

我试图打印所有文件列表的大小，但它抛出错误。 这是代码:

import os

def printSize(fileAbsPath) :
  print os.path.getsize(fileAbsPath)


for folderName, subfolders, filenames in os.walk('/Users/kris/Desktop'):
  for filename in filenames :
    try :
      printSize(os.path.abspath(filename))
    except Exception as err:
      print 'An exception happend : ' + str(err)

并且，错误是:

An exception happend : [Errno 2] No such file or directory: '/Users/kris/Desktop/AutomateBoringStuff/.DS_Store'
An exception happend : [Errno 2] No such file or directory: '/Users/kris/Desktop/AutomateBoringStuff/.gitignore'
An exception happend : [Errno 2] No such file or directory: '/Users/kris/Desktop/AutomateBoringStuff/.gitmodules'
An exception happend : [Errno 2] No such file or directory: '/Users/kris/Desktop/AutomateBoringStuff/.localized'
.
.
.
.
An exception happend : [Errno 2] No such file or directory: '/Users/kris/Desktop/AutomateBoringStuff/BLE Scanner.m4a'
An exception happend : [Errno 2] No such file or directory: '/Users/kris/Desktop/AutomateBoringStuff/Screen Shot 2015-07-23 at 3.30.52 PM.png'

我不知道这是怎么回事。我认为这与“隐藏文件”有点相关，但事实并非如此。

试试这个:

  printSize(os.path.abspath(os.path.join(folderName, filename)))
