Depending on what you're trying to do, you likely want either continuations (which aren't supported in Python directly, but which you can emulate by writing your function in continuation-passing style) or a debugger with rewinding (which is fairly cutting edge, but might exist for Python? PyPy blogged about an early version a few years back). The main use cases for a specific point interrupt are covered by these techniques. That said, Temporal is very similar and supports multiple languages, including Python.
