python - 解压bz2文件

Question

我想解压位于不同路径的不同目录中的文件。并且代码如下，错误是无效的数据流。请帮帮我。非常感谢。

import sys
import os
import bz2
from bz2 import decompress

path = "Dir"
for(dirpath,dirnames,files)in os.walk(path):
   for file in files:
       filepath = os.path.join(dirpath,filename)
       newfile = bz2.decompress(file)
       newfilepath = os.path.join(dirpath,newfile)

Answer 1

bz2.decompress 获取压缩的 data 并对其进行膨胀。您传递的是文件名，而不是文件中的数据!

改为这样做:

zipfile = bz2.BZ2File(filepath) # open the file
data = zipfile.read() # get the decompressed data
newfilepath = filepath[:-4] # assuming the filepath ends with .bz2
open(newfilepath, 'wb').write(data) # write a uncompressed file
