We assume you've already (a) [installed Ocean](install.md), and (b) done [local setup](local-setup.md) or [remote setup](remote-setup.md). This flow works for either one, without any changes between them.
For more information regarding: Data NFT & Datatokens interfaces and how they are implemented in Solidity, we suggest to follow up this [article](../contracts/datanft-and-datatoken.md) and [contracts repo](https://github.com/oceanprotocol/contracts) from GitHub.
Here's an example similar to the `create()` step above, but exposes more parameters to interact with, which requires deeper knowledge about ocean.py usage. The below example points out the creation of an asset and attempts to create a datatoken as well, with the files specified in `DatatokenArguments` class. You have the freedom to customize the data NFT, datatoken and also fields from DDO, such as:
* To disable encryption, use [`ocean.assets.create(..., encrypt_flag=False)`](https://github.com/oceanprotocol/ocean.py/blob/main/ocean\_lib/ocean/ocean\_assets.py#L425).
* To disable compression, use [`ocean.assets.create(..., compress_flag=False)`](https://github.com/oceanprotocol/ocean.py/blob/main/ocean\_lib/ocean/ocean\_assets.py#L426).
* To disable both, use [`ocean.assetspy.create(..., encrypt_flag=False, compress_flag=False)`](https://github.com/oceanprotocol/ocean.py/blob/main/ocean\_lib/ocean/ocean\_assets.py#LL425C8-L426C46).
Calling `create()` like above generates a data NFT, a datatoken for that NFT, and a ddo. This is the most common case. However, sometimes you may want _just_ the data NFT, e.g. if using a data NFT as a simple key-value store. Here's how:
If you call `create()` after this, you can pass in an argument `data_nft_address:string` and it will use that NFT rather than creating a new one.
#### Create a datatoken from a data NFT
Calling `create()` like above generates a data NFT, a datatoken for that NFT, and a ddo object. However, we may want a second datatoken. Or, we may have started with _just_ the data NFT, and want to add a datatoken to it. Here's how:
If you call `create()` after this, you can pass in an argument `deployed_datatokens:List[Datatoken1]` and it will use those datatokens during creation.
#### Create an asset & pricing schema simultaneously
Ocean Assets allows you to bundle several common scenarios as a single transaction, thus lowering gas fees.
Any of the `ocean.assets.create_<type>_asset()` functions can also take an optional parameter that describes a bundled [pricing schema](https://github.com/oceanprotocol/ocean.py/blob/4aa12afd8a933d64bc2ed68d1e5359d0b9ae62f9/ocean\_lib/models/datatoken.py#LL199C5-L219C10) (Dispenser or Fixed Rate Exchange).
