Import alias
An import alias is an alternate name bound to an imported module, namespace, or other imported program element for use in source code.
Python Workout: 50 ten-minute exercises
A module alias is an alternate name bound to an imported module by an import statement using as.
- How it is used
- Shortens module references when names are long or used repeatedly.
- How deep it goes
- Defines alias syntax and namespace behavior, but stops short of deeper import machinery.
- Examples
- Uses mymod as mm and numpy as np as concrete alias forms.
- What you can do after
- Apply module aliases through Python import statements and use the bound name in subsequent references.

Elixir in Action, Third Edition
An alias is an Elixir directive that binds an alternate name to a module for use in references.
- How it is used
- Reduces qualified-module naming noise when repeatedly calling modules in deep application hierarchies.
- How deep it goes
- Defines explicit and inferred names, then connects aliases to atom-based module resolution and BEAM loading.
- Examples
- Uses Geometry.Rectangle, IO as MyIO, Rectangle.area, and MyIO.puts to demonstrate shortened references.
- What you can do after
- Apply it via Elixir syntax to shorten repeated module references while preserving the resolved module identity.

Refactoring to Rust
An import alias is an alternate local name assigned to an imported Rust item or path.
- How it is used
- Simplifies repeated imports and shapes a library’s public API by exposing stable, shorter paths.
- How deep it goes
- Explains local imports, `pub use`, re-exports, module hierarchy, and visibility, but stops short of broader aliasing forms.
- Examples
- Uses a greeter application’s `DayKind` imports and a forest crate’s deeply nested `enter` function.
- What you can do after
- Apply it via Rust `use` and `pub use` to shorten imports and present controlled crate-root names.
