对压缩包的处理是调用 ZipFile 和 TarFile 两个模块来进行的,详细: ZipFile 1 2 4 5 6 7 8 9 10 11 12 importzipfile # 压缩 z = file.ZipFile('laxi.zip', 'w') z.write'a.log') z.write'data.data') z.close) # 解压 z = file.ZipFile('laxi.zip', 'r') z....
标准模块:https://docs.python.org/3/tutorial/modules.html#tut-standardmodules 6.1.3. “Compiled” Python files “编译好的” Python 文件 加载快, 不是运行快 为了加快模块的加载速度,Python 将每个模块的编译版本缓存在__pycache__目录中,名称为 module.version.pyc,其中版本编码了编译文件的格式;它通常包...

In this case there happens to be a straightforward mapping between the module’s attributes and the global names defined in the module: they share the same namespace!1 顺便说说, 我称 Python 中任何一个"."之后的命名为属性 —— 举个例子, 表达式 z.real 中, real 是对象 z 的一个属性. ...

以下模块直接支持通用的数据打包和压缩格式:zlib, gzip, bz2, lzma, zipfile 以及tarfile。 >>> import zlib >>> s = b'witch which has which witches wrist watch' >>> len(s) 41 >>> t = zlib.compress(s) >>> len(t) 37 >>> zlib.decompress(t) b'witch which has which witches wrist ...
The Python Standard Library also supports creating TAR and ZIP archives using the high-level methods in the shutil module. The archiving utilities in shutil allow you to create, read, and extract ZIP and TAR archives. These utilities rely on the lower level tarfile and zipfile modules. Working...
In the Python standard library, you’ll also find tarfile, which supports the TAR archiving format. There’s also a module called gzip, which provides an interface to compress and decompress data, similar to how the GNU Gzip program does it. For example, you can use gzip to create a comp...
