How to create a p2sh transaction with a scriptsig of OP_true? How can I create a p2sh transaction with a scriptsig containing OP_TRUE only, removing the need for a digital signature, which will be broadcasted and mined?

Also could some one provide an example of such a transaction?
Here you have an example of a transaction spending from a P2PKH output and creating a P2SH output with an OP_1.
And here you have the counterpart, a transaction spending from the first one (with an input script '0151') and generating a P2PKH output.
I've created both using a Python library i'm coauthor of. You can check it out here.
