Hi. There is an error in file [Tools/demo/rpython.py](https://github.com/python/cpython/blob/main/Tools/demo/rpython.py) at line 22.
The original statement is port = int(port[i+1:]), but it will crash if the port is specified as parameters.
The correct code should be port = int(host[i+1:]). Then the program can read specified port from parameter sys.argv[1].
