This is documentation for an old release of SciPy (version 0.17.0). Read this page in the documentation of the latest stable release (version 1.15.1).
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]) | Load MATLAB file :Parameters: file_name : str Name of the mat file (do not need .mat extension if appendmat==True) Can also pass open file-like object. |
| 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 :Parameters: file_name : str Name of the mat file (do not need .mat extension if appendmat==True) Can also pass open file-like object. |
IDL® files¶
| readsav(file_name[, idict, python_dict, ...]) | Read an IDL .sav file :Parameters: file_name : str Name of the IDL save file. |
Matrix Market files¶
| mminfo(source) | Return size and storage parameters from Matrix Market file-like ‘source’. |
| mmread(source) | 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. |
Unformatted Fortran files¶
| FortranFile(filename[, mode, header_dtype]) | A file object for unformatted sequential files from Fortran code. |
Netcdf¶
| netcdf_file(filename[, mode, mmap, version, ...]) | A file object for NetCDF data. |
| netcdf_variable(data, typecode, size, shape, ...) | A data object for the netcdf module. |
Harwell-Boeing files¶
| hb_read(file) | Read HB-format file. |
| hb_write(file, m[, hb_info]) | Write HB-format file. |
Wav sound files (scipy.io.wavfile)¶
| read(filename[, mmap]) | Return the sample rate (in samples/sec) and data from a WAV file :Parameters: filename : string or open file handle Input wav file. |
| write(filename, rate, data) | Write a numpy array as a WAV file :Parameters: filename : string or open file handle Output wav file rate : int The sample rate (in samples/sec). |
| WavFileWarning |
Arff files (scipy.io.arff)¶
| loadarff(f) | Read an arff file. |
| MetaData(rel, attr) | Small container to keep useful informations on a ARFF dataset. |
