# Run Python Tools With `uvx`
|
||
|
||
The [`uvx`](https://docs.astral.sh/uv/guides/tools/) binary which gets installed
|
||
as part of `uv` is equivalent to using `uv tool run`. It installs the specified
|
||
tool into an isolated, throwaway environment and then runs it from that
|
||
environment. This is useful for running standalone Python tools that don't
|
||
necessarily need to know anything about or use a specific codebase.
|
||
|
||
A dummy example of this is the classic `cowsay` program.
|
||
|
||
```bash
|
||
❯ uvx cowsay -t "Python tooling is so powerful\!"
|

||
As for some more practical examples, here I can use `rich-cli` to render and
|
||
view a markdown file like a `README.md` right in the terminal.
|
||
|
||
```bash
|
||
❯ uvx --from rich-cli rich README.md --markdown --pager
|
||
```
|
||
|
||
Or how about trying out the latest version of a tool like `ruff` that differs
|
||
from the version currently installed for the target project.
|
||
|
||
```bash
|
||
❯ uvx ruff@latest check .
|
||
```
|
||
|
||
As an example of another standalone tool, here is `yt-dlp` to grab a video from
|
||
YouTube.
|
||
|
||
```bash
|
||
❯ uvx yt-dlp "https://www.youtube.com/watch?v=U3-43VBqpPc"
