[Python] Solana swap transation

Please help me to create swap transaction using solana and solders, there are not that many docs for Python and many legacy examples

using solana 0.36 and solders 0.23

# 1) Get a single quote object
quote_url = (
"https://quote-api.jup.ag/v6/quote"
f"?inputMint=So11111111111111111111111111111111111111112"
f"&outputMint={token_addr}"
f"&amount={lamports_in}"
"&slippageBps=50"
)
quote_resp = requests.get(quote_url, timeout=10).json()
if "routePlan" not in quote_resp or not quote_resp["routePlan"]:
print(f"[WARN] No routePlan for {token_addr}")
return None

# 2) Construct the swap request
swap_req = {
"quoteResponse": quote_resp, # Pass the entire quote here
"userPublicKey": str(WALLET_PUBKEY),
"destinationWallet": str(WALLET_PUBKEY), # optional, can be same as userPublicKey
"wrapAndUnwrapSol": True
}

swap_url = "https://quote-api.jup.ag/v6/swap"
swap_resp = requests.post(swap_url, json=swap_req, timeout=10).json()
if "swapTransaction" not in swap_resp:
print(f"[ERROR] No 'swapTransaction' in Jupiter swap response: {swap_resp}")
return None

tx = # ???


send_resp = client.send_transaction(tx)
signature = send_resp["result"]
print(f"[BUY] {token_addr}, signature={signature}")
return signature
