When building CLI tools, Python and Rust offer very different tradeoffs. Python provides rapid development and a rich ecosystem, while Rust delivers blazing performance and zero-cost abstractions.
Python CLIs
Python's Click and Typer libraries make it incredibly easy to build feature-rich CLIs. The dynamic nature of Python allows rapid iteration.
Rust CLIs
Rust's Clap library combined with its performance characteristics make it ideal for tools that need to be fast and have minimal dependencies. Single binary distribution is a huge advantage.
