[Python] Come scrivere un array di bytes in un file binario

[Patrizio.Ferlito a b-source.ch]

soluzione trovata:

    file = open(fileName, 'wb')
    for entry in bytes:
        file.write(struct.pack('b', entry))
    file.close()

e verifica del file prodotto:

jar tvf /products/.../DummyEvent-sbconfig.jar

Questo vuol dire che str(bytes) ha quella rappresentazione. Cosa ti
aspettavi invece?

Potresti provare a usare

output_file.write(repr(bytes))
