Python中使用gzip模块压缩文件的简单教程
压缩数据创建gzip文件
先看一个略麻烦的做法
import StringIO,gzip content = 'Life is short.I use python' zbuf = StringIO.StringIO() zfile = gzip.GzipFile(mode='wb', compresslevel=9, fileobj=zbuf) zfile.write(content) zfile.close()
但其实有个快捷的封装，不用用到StringIO模块
f = gzip.open('file.gz', 'wb')
f.write(content)
f.close()
压缩已经存在的文件
python2.7后，可以用with语句
import gzip
with open("/path/to/file", 'rb') as plain_file:
with gzip.open("/path/to/file.gz", 'wb') as zip_file:
zip_file.writelines(plain_file)
如果不考虑跨平台，只在linux平台，下面这种方式更直接
from subprocess import check_call
check_call('gzip /path/to/file',shell=True)

Can vs code run in Windows 8
Apr 15, 2025 pm 07:24 PM
VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.
