Numpy binary files (NPY, NPZ)
load (file[, mmap_mode, allow_pickle, ...]) | Load arrays or pickled objects from .npy , .npz or pickled files. |
save (file, arr[, allow_pickle, fix_imports]) | Save an array to a binary file in NumPy .npy format. |
savez (file, *args, **kwds) | Save several arrays into a single file in uncompressed .npz format. |
savez_compressed (file, *args, **kwds) | Save several arrays into a single file in compressed .npz format. |
The format of these binary file types is documented in http://docs.scipy.org/doc/numpy/neps/npy-format.html
Text files
loadtxt (fname[, dtype, comments, delimiter, ...]) | Load data from a text file. |
savetxt (fname, X[, fmt, delimiter, newline, ...]) | Save an array to a text file. |
genfromtxt (fname[, dtype, comments, ...]) | Load data from a text file, with missing values handled as specified. |
fromregex (file, regexp, dtype) | Construct an array from a text file, using regular expression parsing. |
fromstring (string[, dtype, count, sep]) | A new 1-D array initialized from raw binary or text data in a string. |
ndarray.tofile (fid[, sep, format]) | Write array to a file as text or binary (default). |
ndarray.tolist () | Return the array as a (possibly nested) list. |
Raw binary files
fromfile (file[, dtype, count, sep]) | Construct an array from data in a text or binary file. |
ndarray.tofile (fid[, sep, format]) | Write array to a file as text or binary (default). |
array2string (a[, max_line_width, precision, ...]) | Return a string representation of an array. |
array_repr (arr[, max_line_width, precision, ...]) | Return the string representation of an array. |
array_str (a[, max_line_width, precision, ...]) | Return a string representation of the data in an array. |
Memory mapping files
memmap | Create a memory-map to an array stored in a binary file on disk. |
Text formatting options
Base-n representations
binary_repr (num[, width]) | Return the binary representation of the input number as a string. |
base_repr (number[, base, padding]) | Return a string representation of a number in the given base system. |
Data sources
DataSource ([destpath]) | A generic data source file (file, http, ftp, ...). |
