### 3. Get account
|

|

To store value and execute transactions on the XRP Ledger, you need an account: a [set of keys](../../../concepts/accounts/cryptographic-keys.md#key-components) and an [address](../../../concepts/accounts/addresses.md) that's been [funded with enough XRP](../../../concepts/accounts/index.md#creating-accounts) to meet the [account reserve](../../../concepts/accounts/reserves.md). The address is the identifier of your account and you use the [private key](../../../concepts/accounts/cryptographic-keys.md#private-key) to sign transactions that you submit to the XRP Ledger.

To create and fund an account on the Testnet, `xrpl-py` provides the [`generate_faucet_wallet`](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.wallet.html#xrpl.wallet.generate_faucet_wallet) method.

#### Derive an X-Address

||||
|
||||
You can use `xrpl-py`'s [`xrpl.core.addresscodec`](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.core.addresscodec.html) module to derive an [X-address](https://xrpaddress.info/) from the `Wallet.address` field.

The X-address format [packs the address and destination tag](https://github.com/XRPLF/XRPL-Standards/issues/6) into a more user-friendly value.

### 4. Query the XRP Ledger
|
||||
|
||||
{% step id="query-xrpl-tag" %}
|
||||
You can query the XRP Ledger to get information about [a specific account](../../../references/http-websocket-apis/public-api-methods/account-methods/index.md), [a specific transaction](../../../references/http-websocket-apis/public-api-methods/transaction-methods/tx.md), the state of a [current or a historical ledger](../../../references/http-websocket-apis/public-api-methods/ledger-methods/index.md), and [the XRP Ledger's decentralized exchange](../../../references/http-websocket-apis/public-api-methods/path-and-order-book-methods/index.md). You need to make these queries, among other reasons, to look up account info to follow best practices for [reliable transaction submission](../../../concepts/transactions/reliable-transaction-submission.md).
|
||||
|
||||
Here, we use `xrpl-py`'s [`xrpl.account`](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.account.html) module to look up information about the account we got in the previous step.
|
||||
Use the [account_info method][] to look up information about the account you got in the previous step. Use a request model like `AccountInfo` to validate the request format and catch errors sooner.

The response fields that you want to inspect in most cases are:
|
||||
|
||||
- `account_data.Sequence` — This is the sequence number of the next valid transaction for the account. You need to specify the sequence number when you prepare transactions. With `xrpl-py`, you can use the [`get_next_valid_seq_number`](https://xrpl-py.readthedocs.io/en/latest/source/xrpl.account.html#xrpl.account.get_next_valid_seq_number) to get this automatically from the XRP Ledger. See an example of this usage in the project [README](https://github.com/XRPLF/xrpl-py#serialize-and-sign-transactions).
|
||||
|
||||
- `account_data.Balance` — This is the account's balance of [XRP, in drops][]. You can use this to confirm that you have enough XRP to send (if you're making a payment) and to meet the [current transaction cost](../../../concepts/transactions/transaction-cost.md#current-transaction-cost) for a given transaction.
|
||||
|
||||
- `validated` — Indicates whether the returned data is from a [validated ledger](../../../concepts/ledgers/open-closed-validated-ledgers.md). When inspecting transactions, it's important to confirm that [the results are final](../../../concepts/transactions/finality-of-results/index.md) before further processing the transaction. If `validated` is `true` then you know for sure the results won't change. For more information about best practices for transaction processing, see [Reliable Transaction Submission](../../../concepts/transactions/reliable-transaction-submission.md).
