Input and output (`scipy.io`)#

SciPy has many modules, classes, and functions available to read data from and write data to a variety of file formats.

MATLAB® files#

`loadmat`(file_name[, mdict, appendmat, spmatrix])	Load MATLAB file.
`savemat`(file_name, mdict[, appendmat, ...])	Save a dictionary of names and arrays into a MATLAB-style .mat file.
`whosmat`(file_name[, appendmat])	List variables inside a MATLAB file.

For low-level MATLAB reading and writing utilities, see scipy.io.matlab.

readsav(file_name[, idict, python_dict, ...])

Read an IDL .sav file.

`mminfo`(source)	Return size and storage parameters from Matrix Market file-like 'source'.
`mmread`(source, *[, spmatrix])	Reads the contents of a Matrix Market file-like 'source' into a matrix.
`mmwrite`(target, a[, comment, field, ...])	Writes the sparse or dense array a to Matrix Market file-like target.

`FortranFile`(filename[, mode, header_dtype])	A file object for unformatted sequential files from Fortran code.
`FortranEOFError`	Indicates that the file ended properly.
`FortranFormattingError`	Indicates that the file ended mid-record.

`netcdf_file`(filename[, mode, mmap, version, ...])	A file object for NetCDF data.
`netcdf_variable`(data, typecode, size, shape, ...)	A data object for netcdf files.

`hb_read`(path_or_open_file, *[, spmatrix])	Read HB-format file.
`hb_write`(path_or_open_file, m[, hb_info])	Write HB-format file.

`read`(filename[, mmap])	Open a WAV file.
`write`(filename, rate, data)	Write a NumPy array as a WAV file.
`WavFileWarning`

`loadarff`(f)	Read an arff file.
`MetaData`(rel, attr)	Small container to keep useful information on a ARFF dataset.
