no-exceptions 0.1.0

Errors as values for Python.

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:

def some_func() -> float:
    ...
    try:
        return numerator / denominator
    except ZeroDivisionError:
        return 0.0

to this:

from no_exceptions import try_expecting

def some_func() -> float:
    ...
    return try_expecting(lambda: numerator / denominator, ZeroDivisionError).unwrap_or(0.0)
