# Click

Click is a Python package for creating beautiful command line interfaces
in a composable way with as little code as necessary. It's the "Command
Line Interface Creation Kit". It's highly configurable but comes with
sensible defaults out of the box.

It aims to make the process of writing command line tools quick and fun
while also preventing any frustration caused by the inability to
implement an intended CLI API.

Click in three points:

-   Arbitrary nesting of commands
-   Automatic help page generation
-   Supports lazy loading of subcommands at runtime


## A Simple Example

```python
import click

@click.command()
@click.option("--count", default=1, help="Number of greetings.")
@click.option("--name", prompt="Your name", help="The person to greet.")
def hello(count, name):
    """Simple program that greets NAME for a total of COUNT times."""
    for _ in range(count):
        click.echo(f"Hello, {name}!")

if __name__ == '__main__':
    hello()
```

```
$ python hello.py --count=3
Your name: Click
Hello,...

## AI interpretation — verify before relying

Click is a Python framework for building command-line interfaces with decorators, automatic help generation, and composable nested commands with minimal boilerplate.

Verdict: Click is a mature, actively maintained top-100 PyPI package with zero known vulnerabilities, permissive licensing, and trivial install friction. Ideal for any Python CLI project.
