get_pkg_data_filenames

astropy.utils.data.get_pkg_data_filenames(datadir, pattern=u'*')

Returns the path of all of the data files in a given directory that match a given glob pattern.

Parameters:

datadir : str

Name/location of the desired data files. One of the following:

• The name of a directory included in the source distribution. The path is relative to the module calling this function. For example, if calling from astropy.pkname, use 'data' to get the files in astropy/pkgname/data.
• Remote URLs are not currently supported.

pattern : str, optional

A UNIX-style filename glob pattern to match files. See the glob module in the standard library for more information. By default, matches all files.

Returns:

filenames : iterator of str

Paths on the local filesystem in datadir matching pattern.

Examples

This will retrieve the contents of the data file for the astropy.wcs tests:

from astropy.utils.data import get_pkg_data_filenames

for fn in get_pkg_data_filename('maps', '*.hdr'):
    with open(fn) as f:
        fcontents = f.read()
