quickassert

A Python runtime service: Assertion admin with generated exception

Short Description from v.1.0 (first)

Creates assertion administor (access) on relatively small prodjects, in order to save time used in raising and writing exceptions. It generate automatically a one-pattern exception.

Quick Use

First, run the command:

pip install quickassert

When the installation is done, an example is:

from quickassert import *

entry_assert = new_assert(_global=False)  # necessary to call once if AUTO_NEW_ASSERT is False

# declare assertion test named digit
entry_assert['digit'] = lambda x: 0 <= x < 10


def enter_digit(d: int) -> None:
    if isinstance(d, int):
        entry_assert.digit('d', d)
        print('O.K.')
        return
    raise TypeError('d must be int')

where one can obtain:

>>> enter_digit(4)
>>> O.K.

>>> enter_digit(23)
>>> ValueError: d must be digit

Coming in following versions

• Better exception and message handling.
• Mode with inspection, no need to pass variable name if same (maybe with a decorator)
• Smallest tree checking, for optimisation, for example: (x > 3) & (x > 5) ~ (x > 5)
• Typing check adapted.
• And maybe more
