I tried many times and read the code of scalecodec, but I still can't find a suitable way to convert this type, I need your help, pls

[arjanz]

A pointer I can give is that in the latest version of SubstrateInterface there is a function that can provide type composition info for storage functions: https://github.com/polkascan/py-substrate-interface#type-decomposition-information

Last week I actually took some effort to collect this information it generates for well-known Substrate runtimes into a extensive Substrate metadata website, so this is the information about the storage function you mentioned:

https://polkascan.github.io/py-substrate-metadata-docs/khala/#properties

You should read this as follows:

call = substrate.query(
    'RmrkCore', 'Properties', ['u32', (None, 'u32'), 'Bytes']
)

• u32 is obviously a 32-bit integer

• (None, 'u32') means either None or a u32 (This is an Option in RUST)

• Bytes is an arbitrary str, bytes or hex-string

Let me know if this helps

result = Substrate().substrate.query('RmrkCore', 'Properties',
                                     ['10324', (None, '31'), '0x068500be5822de000000000000000000']
                                     )

Before that, I tried https://polkascan.github.io/py-substrate-metadata-docs/khala/#properties to pass parameters, but the above error will appear

result = Substrate().substrate.query('RmrkCore', 'Properties', ['10324', (None, '31'), '0x068500be5822de000000000000000000'] ) print(result)

It should be either None or 31, that parameter is a Option :

result = Substrate().substrate.query('RmrkCore', 'Properties',
                                     [10324, 31, '0x068500be5822de000000000000000000']
                                     )
