Note: in case you want to use cryptocurrency functions in an universal way or e.g. reliably calculate transaction fees for BTC, ETH, Tron and many others, check out the Bitcart project

How to use

from tronex import Tron
from tronex.keys import PrivateKey

client = Tron(network='nile')
# Private key of TJzXt1sZautjqXnpjQT4xSCBHNSYgBkDr3
priv_key = PrivateKey(bytes.fromhex("8888888888888888888888888888888888888888888888888888888888888888"))

txn = (
    client.trx.transfer("TJzXt1sZautjqXnpjQT4xSCBHNSYgBkDr3", "TVjsyZ7fYF3qLF6BQgPmTEZy1xrNNyVAAA", 1_000)
    .memo("test memo")
    .build()
    .inspect()
    .sign(priv_key)
    .broadcast()
)

print(txn)
# > {'result': True, 'txid': '5182b96bc0d74f416d6ba8e22380e5920d8627f8fb5ef5a6a11d4df030459132'}
print(txn.wait())
# > {'id': '5182b96bc0d74f416d6ba8e22380e5920d8627f8fb5ef5a6a11d4df030459132', 'blockNumber': 6415370, 'blockTimeStamp': 1591951155000, 'contractResult': [''], 'receipt': {'net_usage': 283}}

Async Client

import asyncio

from tronex import AsyncTron
from tronex.keys import PrivateKey

# private key of TMisHYBVvFHwKXHPYTqo8DhrRPTbWeAM6z
priv_key = PrivateKey(bytes.fromhex("8888888888888888888888888888888888888888888888888888888888888888"))

async def transfer():
    async with AsyncTron(network='nile') as client:
        print(client)

        txb = (
            client.trx.transfer("TJzXt1sZautjqXnpjQT4xSCBHNSYgBkDr3", "TVjsyZ7fYF3qLF6BQgPmTEZy1xrNNyVAAA", 1_000)
            .memo("test memo")
            .fee_limit(100_000_000)
        )
        txn = await txb.build()
        print(txn)
        txn_ret = await txn.sign(priv_key).broadcast()
        print(txn_ret)
        # > {'result': True, 'txid': 'edc2a625752b9c71fdd0d68117802860c6adb1a45c19fd631a41757fa334d72b'}
        print(await txn_ret.wait())
        # > {'id': 'edc2a625752b9c71fdd0d68117802860c6adb1a45c19fd631a41757fa334d72b', 'blockNumber': 10163821, 'blockTimeStamp': 1603368072000, 'contractResult': [''], 'receipt': {'net_usage': 283}}

if __name__ == '__main__':
    asyncio.run(transfer())

Or close async client manually:

from httpx import AsyncClient, Timeout
from tronex.providers.async_http import AsyncHTTPProvider
from tronex.defaults import CONF_NILE


async def transfer():
    _http_client = AsyncClient(limits=Limits(max_connections=100, max_keepalive_connections=20),
                               timeout=Timeout(timeout=10, connect=5, read=5))
    provider = AsyncHTTPProvider(CONF_NILE, client=_http_client)
    client = AsyncTron(provider=provider)
    print(client)

    priv_key = PrivateKey(bytes.fromhex("8888888888888888888888888888888888888888888888888888888888888888"))
    txb = (
        client.trx.transfer("TJzXt1sZautjqXnpjQT4xSCBHNSYgBkDr3", "TVjsyZ7fYF3qLF6BQgPmTEZy1xrNNyVAAA", 1_000)
        .memo("test memo")
        .fee_limit(100_000_000)
    )
    txn = await txb.build()
    print(txn)
    txn_ret = await txn.sign(priv_key).broadcast()

    print(txn_ret)
    print(await txn_ret.wait())
    await client.close()

if __name__ == '__main__':
    asyncio.run(transfer())
