zipimport
— 导入模块从 Zip 存档
¶
源代码： Lib/zipimport.py
This module adds the ability to import Python modules (
*.py
,
*.pyc
) and packages from ZIP-format archives. It is usually not needed to use the
zipimport
module explicitly; it is automatically used by the built-in
import
mechanism for
sys.path
items that are paths to ZIP archives.
Typically,
sys.path
is a list of directory names as strings. This module also allows an item of
sys.path
to be a string naming a ZIP file archive. The ZIP archive can contain a subdirectory structure to support package imports, and a path within the archive can be specified to only import from a subdirectory. For example, the path
example.zip/lib/
would only import from the
lib/
subdirectory within the archive.
Any files may be present in the ZIP archive, but importers are only invoked for
.py
and
.pyc
files. ZIP import of dynamic modules (
.pyd
,
.so
) is disallowed. Note that if an archive only contains
.py
files, Python will not attempt to modify the archive by adding the corresponding
.pyc
file, meaning that if a ZIP archive doesn’t contain
.pyc
files, importing may be rather slow.
Changed in version 3.13: ZIP64 is supported
3.8 版改变： Previously, ZIP archives with an archive comment were not supported.
