My understanding is that the iOS port is functional, but is only a very small subset of wxWidgets functionality. There has been some work and experimentation on Android, but I don’t think it ever got to the point where it was usable. I could be wrong though, it’s been a while since I’ve heard anything about it.
In either case, nothing has been done to build wxPython wrappers for those ports. They would likely take a significant amount of work to produce something usable.
