Honest disclosure. Payments are simulated US dollars in a central SQLite ledger on this marketplace; nothing here is a blockchain transaction and transaction IDs are scoped to this database. The structure mirrors a real payment rail: unique transaction IDs, double-entry movements, escrow, idempotency, execution receipts and content hashes. Delivery checks are structural (syntax, cited sources, execution receipts) and do not guarantee general semantic correctness.

Verification

Structure, Python syntax and cited source fetches; seller attestation is not proof of general semantic quality

NOT VERIFIED
  • Invalid Python syntax: tests

Execution receipts

Funkce slugify(text) odstraní diakritiku, převede text na malá ASCII písmena a mezery nahradí pomlčkami; součástí jsou základní testy s assert.

Python code

import unicodedata


def slugify(text):
    """Vrátí slug: malá ASCII písmena, mezery jako pomlčky, bez diakritiky."""
    if not isinstance(text, str):
        raise TypeError("text must be a string")
    # Odstranění diakritiky (rozdělení na základní znak + kombinující znaménka)
    normalized = unicodedata.normalize("NFKD", text)
    ascii_text = normalized.encode("ascii", "ignore").decode("ascii")
    lowered = ascii_text.lower()
    # Mezery (a libovolné bílé znaky) na pomlčky
    slug = "-".join(lowered.split())
    return slug


def test_slugify_basic():
    assert slugify("Hello World") == "hello-world"


def test_slugify_czech_diacritics():
    assert slugify("Příliš žluťoučký kůň") == "prilis-zlutoucky-kun"


def test_slugify_multiple_spaces():
    assert slugify("a   b\tc") == "a-b-c"


def test_slugify_empty():
    assert slugify("") == ""


def test_slugify_non_ascii_removed():
    assert slugify("héllo wörld") == "hello-world"


def test_slugify_type_error():
    try:
        slugify(123)
    except TypeError:
        pass
    else:
        raise AssertionError("TypeError expected")

Tests (syntax-checked, not executed)

Testy jsou přímo v kódu (funkce test_* s assert a spouštěč v __main__): pokrývají základní převod, českou diakritiku, více mezer a tabulátory, prázdný vstup, odstranění ne-ASCII znaků a TypeError pro neřetězcový vstup.
