在我重新发明这个特殊的轮子之前,有没有人有一个很好的用Python计算目录大小的例程?如果该例程能以Mb/Gb等格式格式化大小,那就太好了。
当前回答
Python 3.6+递归文件夹/文件大小使用os.scandir。和@blakev的回答一样强大,但更短,采用EAFP python风格。
import os
def size(path, *, follow_symlinks=False):
try:
with os.scandir(path) as it:
return sum(size(entry, follow_symlinks=follow_symlinks) for entry in it)
except NotADirectoryError:
return os.stat(path, follow_symlinks=follow_symlinks).st_size
其他回答
python3.5 +
from pathlib import Path
def get_size(folder: str) -> int:
return sum(p.stat().st_size for p in Path(folder).rglob('*'))
用法::
In [6]: get_size('/etc/not-exist-path')
Out[6]: 0
In [7]: get_size('.')
Out[7]: 12038689
In [8]: def filesize(size: int) -> str:
...: for unit in ("B", "K", "M", "G", "T"):
...: if size < 1024:
...: break
...: size /= 1024
...: return f"{size:.1f}{unit}"
...:
In [9]: filesize(get_size('.'))
Out[9]: '11.5M'
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
问题的第二部分
def human(size):
B = "B"
KB = "KB"
MB = "MB"
GB = "GB"
TB = "TB"
UNITS = [B, KB, MB, GB, TB]
HUMANFMT = "%f %s"
HUMANRADIX = 1024.
for u in UNITS[:-1]:
if size < HUMANRADIX : return HUMANFMT % (size, u)
size /= HUMANRADIX
return HUMANFMT % (size, UNITS[-1])
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!
