# DSL Kata

Python solution uses a different approach because the language lacks a block syntax and multi-line lambdas.

Each of these objects is built inline using readable method names.

This implementation overloads the operators `__str__` for operations on the text and range fields.

```python

print(

    Form(

        CharField(name="user", size="140", label="User Name"),

        id="adidas-form",

    )

)

print("-"*5)

print(

    Form(

        CharField(name="user", size="140", label="User Name"),

        PasswordField(label="Password"),

        id="adidas-form",

    )

)

```

```html

User Name

-----

User Name

Password

```

## Run

```bash

$ python main.py

```

## Strengths

- Single step for creating the request

- Easy to dynamically create criteria

- Operator overloading improves readability

## Weaknesses

- Repetition of the class name

- Literal list used as argument

## TL;DR

In general, there are 3 types of DSL implementations: `fluent interface`, `readable inline method arguments` and `blocks`.

Fluent interfaces is the most effective approach for the static languages.

For Python, readable inline method arguments seemed to be the most idiomatic.
