Summary  
This chapter covers using NumPy’s functions to save and load arrays in both binary and text file formats.  

General domain of usage  
Data persistence and storage.

`NumPy` offers a variety of functions for **saving** and **loading** `numPy` arrays to and from files, such as:
- **`save()`**: Saves an array to a binary file in `NumPy`'s **`.npy`** format;
- **`savez()`**: Saves multiple arrays to a single compressed **`.npz`** file;
- **`savetxt()`**: Saves an array to a text file;
- **`load()`**: Loads an array from a binary file in `NumPy`'s **`.npy`** format;
- **`loadtxt()`**: Loads an array from a text file.
