web3py sendTransaction without private key

Question

I am trying to make a transaction, but failing. I have ganache-cli with 1000 ETHs in each wallet. I am running some python scripts to make transaction. Using this link, I am not able to do so. This document is little outdated, and I am using the following

nonce = web3.eth.getTransactionCount(<address>)
tx = {
      'nonce':nonce,
      'to': <address_2>,
      'value': web3.toWei(100,'ether'),
      'gas':2000000,
      'gasPrice':web3.toWei('50','gwei')
      }
web3.eth.send_transaction(tx)

I get the following error: ValueError: {'message': 'from not found; is required', 'code': -32000, ....

I can do the same thing with private_key but since ganache handles transaction without us signing. I wanted to know how can I create transaction to send Ethers from one wallet to another.

Thank you

Just add from. Eg.

'from': web3.eth.coinbase
