I'm in the midst of working this github --> https://github.com/karask/python-bitcoin-utils/blob/master/examples/spend_p2sh_transaction.py

Sorry as I'm not that good in this. I would like to ask the following:

  1. Where can I create this "transaction input from tx id of UTXO"? This is for Bitcoin UTXO.

I mean is it using bitcoin node? vscode? python in Gitpods? I just want to know where I can run this and able to provide me the TXID along with the Transaction value in it. Like for example snapshot below:

enter image description here

Care to guide me? Please.. Thank you in advance.

    You don't create it; you have it. It's the txid of the transaction that created the output you're trying to spend. Without it, you don't have any coins.

  • Hi @Prayank. Thanks for your reply. I did follow your instructions. However, in the Atom Editor, I'm unable to install bitcoin-utils library and unable to run the script like what you did in your snapshot. It stated here as Traceback (most recent call last): File "C:\GitPod\python-bitcoin-utils-master\bitcoinutils\utils.py", line 13, in <module> from bitcoinutils.constants import SATOSHIS_PER_BITCOIN ModuleNotFoundError: No module named 'bitcoinutils' [Finished in 0.206s]

  • Open "command prompt" as an administrator and run the command "pip install bitcoin-utils" Relaunch Atom Editor and try to run the python code

  • Hi @Prayank. Thanks so much for your prompt reply and good guidance. It really works except for the node_proxy.py --> due to I think this is under "Testnet" and if I change to "Mainnet" do you think, it will automatically connect? Actually, I wanted to create a (new) UTXO with (new) Transaction in order to the TXID Input. do you think I can get it here in the bitcoin-utils library? Or shall I make a new script for this? Please advise, thanks so much in advance.
