# No exceptions

Errors as values for Python. A more functional alternative to `try-except` blocks, offering less indented code and a

chainable API.

- Do you hate exceptions?

- Do you hate the extra indentation they bring?

- Do you hate the convoluted flow of control they seed?

- Do you hate APIs that throw exceptions in not-really-erroneous cases (like `ZeroDivisionError`, `KeyError`,

`IndexError`, `StopIteration`)?

Use this package to switch from this:

```python

def some_func() -> float:

    ...

    try:

        return numerator / denominator

    except ZeroDivisionError:

        return 0.0

```

to this:

```python

from no_exceptions import try_expecting

def some_func() -> float:

    ...

    return try_expecting(lambda: numerator / denominator, ZeroDivisionError).unwrap_or(0.0)

```
