numpoly.savez_compressed

numpoly.savez_compressed(file: os.PathLike, *args: numpoly.typing.PolyLike, **kwargs: numpoly.typing.PolyLike) → None

Save several arrays into a single file in uncompressed .npz format.

If arguments are passed in with no keywords, the corresponding variable names, in the .npz file, are ‘arr_0’, ‘arr_1’, etc. If keyword arguments are given, the corresponding variable names, in the .npz file will match the keyword names.

Args:

file:

Either the filename (string) or an open file (file-like object) where the data will be saved. If file is a string or a Path, the .npz extension will be appended to the filename if it is not already there.

args:

Arrays to save to the file. Since it is not possible for Python to know the names of the arrays outside savez_compressed, the arrays will be saved with names “arr_0”, “arr_1”, and so on. These arguments can be any expression.

kwds:

Arrays to save to the file. Arrays will be saved in the file with the keyword names.

Example:

>>> q0, q1 = numpoly.variable(2)
>>> poly = numpoly.polynomial([q0, q1-1])
>>> array = numpy.array([1, 2])
>>> numpoly.savez_compressed("/tmp/savez.npz", a=array, p=poly)
>>> numpoly.load("/tmp/savez.npz")
{'a': array([1, 2]), 'p': polynomial([q0, q1-1])}
>>> numpoly.savez_compressed("/tmp/savez.npz", array, poly)
>>> out = numpoly.load("/tmp/savez.npz")
>>> out["arr_0"], out["arr_1"]
(array([1, 2]), polynomial([q0, q1-1]))
