# Mint and Burn NFTs Using Python
This example shows how to:
1. Mint new Non-fungible Tokens (NFTs).
2. Get a list of existing NFTs.
3. Delete (Burn) an NFT.
[](/docs/img/quickstart-py10.png)
# Usage
You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/py/) archive to try the sample in your own browser.
## Get Accounts
1. Open and run `lesson3-mint-token.py`.
2. Get test accounts.
1. If you have existing Testnet account seeds:
1. Paste the standby account seed in the **Standby Seed** field.
2. Click **Get Standby Account**.
3. Paste the operational account seed in the **Operational Seed** field.
4. Click **Get Operational Account**.
2. If you do not have existing Testnet accounts:
1. Click **Get New Standby Account**.
2. Click **Get New Operational Account**.
3. Click **Get Standby Account Info**.
4. Click **Get Op Account Info**.
[](/docs/img/quickstart-py11.png)
## Mint an NFT
To mint a non-fungible token object:
1. Set the **Flags** field. For testing purposes, we recommend setting the value to _8_. This sets the _tsTransferable_ flag, meaning that the NFT can be transferred to another account. Otherwise, the NFT can only be transferred back to the issuing account. See [NFToken Mint](/docs/references/protocol/transactions/types/nftokenmint/#nftokenmint-flags) for information about all of the available flags for minting NFTs.
2. Enter the **NFT URI**. This is a URI that points to the data or metadata associated with the NFT. You can use the sample URI provided if you do not have one of your own.
3. Enter the **Transfer Fee**, a percentage of the proceeds from future sales of the NFT that will be returned to the original creator. This is a value of 0-50000 inclusive, allowing transfer rates between 0.000% and 50.000% in increments of 0.001%. If you do not set the **Flags** field to allow the NFT to be transferrable, set this field to 0.
4. Optionally a **Taxon** value as an integer. If you choose not to use a taxon, enter _0_.
4. Click **Mint NFT**.
[](/docs/img/quickstart-py12.png)
## Get Tokens
Click **Get NFTs** to get a list of NFTs owned by the account.
[](/docs/img/quickstart-py13.png)
## Burn a Token
The current owner of an NFT can always destroy (or _burn_) an NFT.
To permanently destroy an NFT:
1. Enter the **Token ID**.
2. Click **Burn NFT**.

# Code Walkthrough
You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/py/) archive to examine the code samples.
## mod3.py
This module contains the new methods `mint_token`, `get_tokens`, and `burn_token`.
Import dependencies and set global variable.
```python
import xrpl
from xrpl.clients import JsonRpcClient
from xrpl.wallet import Wallet
from xrpl.models.requests import AccountNFTs
testnet_url = "https://s.altnet.rippletest.net:51234"
```
## mintToken
Pass the arguments account seed, NFT URI, transaction flags, the transfer fee, and optional taxon.
```python
def mint_token(seed, uri, flags, transfer_fee, taxon):
"""mint_token"""
```
Get the account wallet and a client instance.
```python
minter_wallet=Wallet.from_seed(seed)
client=JsonRpcClient(testnet_url)
```
Define the mint transaction. Note that the NFT URI must be converted to a hex string.
```python
mint_tx=xrpl.models.transactions.NFTokenMint(
account=minter_wallet.address,
uri=xrpl.utils.str_to_hex(uri),
flags=int(flags),
transfer_fee=int(transfer_fee),
nftoken_taxon=int(taxon)
)
```
Submit the transaction and return results.
```python
reply=""
try:
response=xrpl.transaction.submit_and_wait(mint_tx,client,minter_wallet)
reply=response.result
except xrpl.transaction.XRPLReliableSubmissionException as e:
reply=f"Submit failed: {e}"
return reply
```
## getTokens
```python
def get_tokens(account):
"""get_tokens"""
```
Instantiate a client.
```python
client=JsonRpcClient(testnet_url)
```
Prepare the `AccountNFTs` request.
```python
acct_nfts=AccountNFTs(
account=account
)
```
Send the request and return the result.
```python
response=client.request(acct_nfts)
return response.result
```
## burn_token
Pass the owner's seed value and the NFT ID.
```python
def burn_token(seed, nftoken_id):
"""burn_token"""
```
Get the owner wallet and client instance.
```python
owner_wallet=Wallet.from_seed(seed)
client=JsonRpcClient(testnet_url)
```
Define the NFTokenBurn transaction.
```python
burn_tx=xrpl.models.transactions.NFTokenBurn(
account=owner_wallet.address,
nftoken_id=nftoken_id
)
```
Submit the transaction and return results.
```python
reply=""
try:
response=xrpl.transaction.submit_and_wait(burn_tx,client,owner_wallet)
reply=response.result
except xrpl.transaction.XRPLReliableSubmissionException as e:
reply=f"Submit failed: {e}"
return reply
```
## lesson3-mint-token.py
This module builds on `lesson2-create-trustline-send-currency.py`. Changes are noted below.
```python
import tkinter as tk

)
```
Import methods from `mod3.py`.
```python
from mod3 import (
mint_token,
