Input and output¶
NPZ files¶
| load(file[, mmap_mode]) | Load an array(s) or pickled objects from .npy, .npz, or pickled files. |
| save(file, arr) | 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. |
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). |
String formatting¶
| 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. |
Text formatting options¶
| set_printoptions([precision, threshold, ...]) | Set printing options. |
| get_printoptions() | Return the current print options. |
| set_string_function(f[, repr]) | Set a Python function to be used when pretty printing arrays. |
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, ...). |
