  • Utility Functions

The Core Utility package implements the utility functions and objects that was created on sub-package namespace, ddeutil, design for independent installation. I make this package able to extend with any sub-extension with this namespace. This namespace able to scale out the coding with folder structure design. You can add any extension features and import by import ddeutil.{extension}.

Note

This package provide the Base Utility functions and objects for any sub-namespace package that use for data function or application.

Installation

pip install -U ddeutil

Features

This Core package will implement all of reusable functions and objects that does not re-create again because it is basic code but has a lot of coding.

OnlyOne

from ddeutil.core import onlyone

assert 'a' == onlyone(['a', 'b'], ['a', 'b', 'c'])
assert 'c' == onlyone(('a', 'b'), ['c', 'e', 'f'])
assert onlyone(['a', 'b'], ['c', 'e', 'f'], default=False) is None

Instance Check

from ddeutil.core import isinstance_check
from typing import Union, Optional

assert isinstance_check("s", str)
assert isinstance_check(["s"], list[str])
assert isinstance_check(("s", "t"), tuple[str, ...])
assert not isinstance_check(("s", "t"), tuple[str])
assert isinstance_check({"s": 1, "d": "r"}, dict[str, Union[int, str]])
assert isinstance_check("s", Optional[str])
assert isinstance_check(1, Optional[Union[str, int]])
assert not isinstance_check("s", list[str])
