Since I am using web3 = Web3(HTTPProvider('https://mainnet.infura.io/root@123'))

That's why I have to use sendrawtransaction for ether transaction . Now what is the process of write sendrawtransaction in PYTHON ?

And if there is any other process of transaction using this Httpprovider in pythhon then please mention .

If I understand you correctly, you're just trying to figure out how to send a transaction using web3.py. If so, something like this should work:

web3.eth.sendTransaction({
    'from': '0x...',
    'to': '0x...',
    'value': web3.toWei(1, 'ether'),
})

You can sign a transaction with pyethereum. See the pyethereum answer here: Create and sign OFFLINE raw transactions?

You may refer the official doc here.
It gives an example as follow,

>>> import rlp
>>> from ethereum.transactions import Transaction
>>> tx = Transaction(
    nonce=web3.eth.getTransactionCount(web3.eth.coinbase),
    gasprice=web3.eth.gasPrice,
    startgas=100000,
    to='0xd3cda913deb6f67967b99d67acdfa1712c293601',
    value=12345,
    data=b'',
)
>>> tx.sign(the_private_key_for_the_from_account)
>>> raw_tx = rlp.encode(tx)
>>> raw_tx_hex = web3.toHex(raw_tx)
>>> web3.eth.sendRawTransaction(raw_tx_hex)
'0xe670ec64341771606e55d6b4ca35a1a6b75ee3d5145a99d05921026d1527331'
