## Create a Sell Offer

div
iframe
To create a NFT sell offer:

1. Enter the **Amount** of the sell offer in drops (millionths of an XRP).
2. Enter the **NFT ID** of the NFT you want to sell.
3. Optionally, enter a **Destination** account, the only account that can accept the offer.
4. Optionally, enter a number of seconds until **Expiration**.
5. Click **Create Sell Offer**.
6. Click **Get Offers**.


The important piece of information in the response is the NFT Offer Index, labeled as `nft_offer_index`, which you use to accept the sell offer.

## Accept Sell Offer

Once a sell offer is available, another account can opt to accept the offer and buy the NFT.

To accept an available sell offer:

1. Enter the **NFT Offer Index** (labeled as `nft_offer_index` in the token offer results. This is different from the `NFTokenID`.)
2. Click **Accept Sell Offer**.
3. Click **Get Standby Account Info** and **Get Op Account Info** to update the XRP balances.
4. Click **Get NFTs** for each account to see that the NFT has moved from the Standby account to the Operational account.

## Create a Buy Offer

You can offer to buy an NFT from another account.

To create an offer to buy an NFT:

1. Enter the **Amount** of your offer.
2. Enter the **NFT ID**.
3. Enter the owner’s account string in the **Owner** field.
4. Optionally enter the number of seconds until **Expiration**.
5. Click **Create Buy Offer**.
6. On the Operational side, enter the **NFT ID**.
7. Click **Get Offers** to view the offer and copy the `nft_offer_index`.

# Code Walkthrough

You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/py/) archive to try each of the samples in your own browser.

## mod4.py

This module contains the new methods `create_sell_offer`, `create_buy_offer`, `accept_sell_offer`, `accept_buy_offer`, `get_offers`, and `cancel_offer`.

Import dependencies.


```python
import xrpl
import json
from xrpl.clients import JsonRpcClient
from xrpl.wallet import Wallet
from datetime import datetime
from datetime import timedelta
from xrpl.models.requests import NFTSellOffers
from xrpl.models.requests import NFTBuyOffers
from xrpl.models.transactions import NFTokenAcceptOffer
testnet_url = "https://s.altnet.rippletest.net:51234"
```

## Create Sell Offer

Pass the arguments *seed*, *amount*, *NFT ID*, *expiration* (in seconds, optional), and *destination* (optional).


```python
def create_sell_offer(seed, amount, nftoken_id, expiration, destination):
    """create_sell_offer"""
```

Get the owner wallet and create a client connection.


```python
    owner_wallet = Wallet.from_seed(seed)
    client = JsonRpcClient(testnet_url)
```

If there is an expiration value, convert the current date and time to Ripple time, then add the expiration value.


```python
    expiration_date = datetime.now()
    if expiration != '':
        expiration_date = xrpl.utils.datetime_to_ripple_time(expiration_date)
        expiration_date = expiration_date + int(expiration)
```

Define the sell offer transaction.


```python
    sell_offer_tx=xrpl.models.transactions.NFTokenCreateOffer(
        account=owner_wallet.address,
        nftoken_id=nftoken_id,
        amount=amount,
```

If the sale is designated for a specific destination account, include the `destination` argument.


```python
        destination=destination if destination != '' else None,
```

If the expiration date is present, include the `expiration` argument.


```python
        expiration=expiration_date if expiration != '' else None,
```

Set the `flags` value to *1*, indicating that this is a sell offer.


```python
        flags=1
    )
```

Submit the transaction.


```python
    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(sell_offer_tx,client,owner_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
```

Return the result.


```python
    return reply
```

## Accept Sell Offer

Pass the buyer's seed value and the NFT sell offer index.


```python
def accept_sell_offer(seed, offer_index):
    """accept_sell_offer"""
```

Get the wallet and a client instance.


```python
    buyer_wallet=Wallet.from_seed(seed)
    client=JsonRpcClient(testnet_url)
```

Define the accept offer transaction


```python
    accept_offer_tx=xrpl.models.transactions.NFTokenAcceptOffer(
       account=buyer_wallet.classic_address,
       nftoken_sell_offer=offer_index
    )
```

Sign and fill the transaction.


```python
    signed_tx=xrpl.transaction.safe_sign_and_autofill_transaction(
        accept_offer_tx, buyer_wallet, client)
```

Submit the transaction and report the results.


```python
    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(accept_offer_tx,client,buyer_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply
```

## Create Buy Offer

Pass the buyer *seed*,  *amount*, *NFT ID*, *owner*, *expiration* (in seconds, optional), and *destination* account (optional).


```python
def create_buy_offer(seed, amount, nft_id, owner, expiration, destination):
    """create_buy_offer"""
```

Get the buyer wallet and a client instance.


```python
    buyer_wallet=Wallet.from_seed(seed)
    client=JsonRpcClient(testnet_url)
```

If the *expiration* value is present, get the current date and time, convert it to Ripple time, and add the *expiration* value.


```python
    expiration_date=datetime.now()
    if (expiration!=''):
        expiration_date=xrpl.utils.datetime_to_ripple_time(expiration_date)
        expiration_date=expiration_date + int(expiration)
```

Define the buy offer transaction.


```python
    buy_offer_tx=xrpl.models.transactions.NFTokenCreateOffer(
        account=buyer_wallet.address,
        nftoken_id=nft_id,
        amount=amount,
        owner=owner,
```

IF the *expiration* value is present, include the *expiration* argument.


```python
        expiration=expiration_date if expiration!='' else None,
```

If the *destination* value is present, include the *destination* argument.


```python
        destination=destination if destination!='' else None,
```

Set the *flags* value to *0*, indicating that this is a "buy" offer.


```python
        flags=0
    )
```

Submit the transaction and report the results.


```python
    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(buy_offer_tx,client,buyer_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply
```

## Accept Buy Offer

Pass the buyer's *seed* value and the NFT *offer___index*.


```python
def accept_buy_offer(seed, offer_index):
    """accept_buy_offer"""
```

Get the buyer wallet and a client instance.


```python
    buyer_wallet=Wallet.from_seed(seed)
    client=JsonRpcClient(testnet_url)
```

Define the accept offer transaction.


```python
    accept_offer_tx=xrpl.models.transactions.NFTokenAcceptOffer(
       account=buyer_wallet.address,
       nftoken_buy_offer=offer_index
    )
```

Submit the transaction and report the results


```python
    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(accept_offer_tx,client,buyer_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply
```

## Get Offers

This is a request, rather than a transaction, so there is no need for a wallet.

Pass the *NFT ID*.


```python
def get_offers(nft_id):
    """get_offers"""
```

Create a client instance.


```python
    client=JsonRpcClient(testnet_url)
```

Define the request for buy offers.


```python
    offers=NFTBuyOffers(
        nft_id=nft_id
    )
```

Send the request and capture the response.


```python
    response=client.request(offers)
```

Create the *allOffers* variable to accumulate the offer responses.


```python
    allOffers="Buy Offers:\n"+json.dumps(response.result, indent=4)
```

Define the request for sell offers.


```python
    offers=NFTSellOffers(
        nft_id=nft_id
    )
```

Send the request and capture the response.


```python
    response=client.request(offers)
```

Add the response to the *allOffers* variable and return the results.


```python
    allOffers+="\n\nSell Offers:\n"+json.dumps(response.result, indent=4)
    return allOffers
```

## Cancel Offer

The creator of an offer can cancel it at any time before it is accepted. Anyone can cancel and offer if its expiration data has expired.

Pass the seed and the NFT Offer ID to be canceled.


```python
def cancel_offer(seed, nftoken_offer_ids):
    """cancel_offer"""
```

Get the wallet and a client instance.


```python
    owner_wallet=Wallet(seed, sequence=16237283)
    client=JsonRpcClient(testnet_url)
```

The `nftoken_offers` parameter is an array, rather than a single ID. You can revise the code to accept several offer IDs at one time. Here, the value is added to a new array variable.


```python
    tokenOfferIDs=[nftoken_offer_ids]
```

Define the cancel offer transaction.


```python
    nftSellOffers="No sell offers"
    cancel_offer_tx=xrpl.models.transactions.NFTokenCancelOffer(
                account=owner_wallet.classic_address,
                nftoken_offers=tokenOfferIDs
        )
```

Submit the transaction and return the result.


```python
    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(cancel_offer_tx,client,owner_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply
```

## lesson4-transfer-tokens.py

This module builds on `lesson3-mint-token.py`. Changes are noted below.


```python
import tkinter as tk
import xrpl
import json

from mod1 import get_account, get_account_info, send_xrp
from mod2 import (
    create_trust_line,
    send_currency,
    get_balance,
    configure_account,
)
from mod3 import (
    mint_token,
    get_tokens,
    burn_token,
)
```

Import new methods from `mod4.py`.


```python
from mod4 import (
    create_sell_offer,
    create_buy_offer,
    get_offers,
    cancel_offer,
    accept_sell_offer,
    accept_buy_offer,
)
```

Add handlers for creating, retrieving, and canceling buy and sell offers.


```python
