如果你使用的是Windows操作系统，你可以:

通过以下方式安装pywin32模块:

PIP安装pywin32

然后编码如下:

import win32com.client as com

def get_folder_size(path):
   try:
       fso = com.Dispatch("Scripting.FileSystemObject")
       folder = fso.GetFolder(path)
       size = str(round(folder.Size / 1048576))
       print("Size: " + size + " MB")
   except Exception as e:
       print("Error --> " + str(e))

import os
def get_size(path = os.getcwd()):
    print("Calculating Size: ",path)
    total_size = 0
    #if path is directory--
    if os.path.isdir(path):
      print("Path type : Directory/Folder")
      for dirpath, dirnames, filenames in os.walk(path):
          for f in filenames:
              fp = os.path.join(dirpath, f)
              # skip if it is symbolic link
              if not os.path.islink(fp):
                  total_size += os.path.getsize(fp)
    #if path is a file---
    elif os.path.isfile(path):
      print("Path type : File")
      total_size=os.path.getsize(path)
    else:
      print("Path Type : Special File (Socket, FIFO, Device File)" )
      total_size=0
    bytesize=total_size
    print(bytesize, 'bytes')
    print(bytesize/(1024), 'kilobytes')
    print(bytesize/(1024*1024), 'megabytes')
    print(bytesize/(1024*1024*1024), 'gegabytes')
    return total_size


x=get_size("/content/examples")

我相信这很有帮助!文件夹和文件!

Chris的回答很好，但可以通过使用set来检查已看到的目录来使其更加惯用，这也避免了对控制流使用异常:

def directory_size(path):
    total_size = 0
    seen = set()

    for dirpath, dirnames, filenames in os.walk(path):
        for f in filenames:
            fp = os.path.join(dirpath, f)

            try:
                stat = os.stat(fp)
            except OSError:
                continue

            if stat.st_ino in seen:
                continue

            seen.add(stat.st_ino)

            total_size += stat.st_size

    return total_size  # size in bytes

递归的一行代码:

def getFolderSize(p):
   from functools import partial
   prepend = partial(os.path.join, p)
   return sum([(os.path.getsize(f) if os.path.isfile(f) else getFolderSize(f)) for f in map(prepend, os.listdir(p))])

不可否认，这有点像黑客，只适用于Unix/Linux。

它匹配du -sb。因为实际上这是一个Python bash包装器，它运行du -sb。命令。

import subprocess

def system_command(cmd):
    """"Function executes cmd parameter as a bash command."""
    p = subprocess.Popen(cmd,
                         stdout=subprocess.PIPE,
                         stderr=subprocess.PIPE,
                         shell=True)
    stdout, stderr = p.communicate()
    return stdout, stderr

size = int(system_command('du -sb . ')[0].split()[0])

import os

def get_size(path):
    total_size = 0
    for dirpath, dirnames, filenames in os.walk(path):
        for f in filenames:
            if os.path.exists(fp):
                fp = os.path.join(dirpath, f)
                total_size += os.path.getsize(fp)

    return total_size   # in megabytes

谢谢monkut & troex!
