# import_download_cache

astropy.utils.data.import_download_cache(filename_or_obj, urls=None, update_cache=False, pkgname='astropy')

  Imports the contents of a ZIP file into the cache.

  Each member of the ZIP file should be named by a quoted version of the URL whose contents it stores. These names are decoded with `unquote()`.

  Parameters:
    filename_or_obj `python:str` or python:file-like object

      Where the stored ZIP file is. Must be something the `zipfile` module can read from.

    urls `set` of `python:str` or `python:list` of `python:str` or `python:None`

      The URLs to import from the ZIP file. The default is all URLs in the file.

    update_cache bool, optional

      If True, any entry in the ZIP file will overwrite the value in the cache; if False, leave untouched any entry already in the cache.

    pkgname `str`, optional

      The package name to use to locate the download cache. i.e. for `pkgname='astropy'` the default cache location is `~/.cache/astropy`.
