There are several problems here. First of all, one either subclasses
Thread and implements run - then your code should look like this:
class ThreadTwo(Thread):
def run(self):
tcpip.tcpip()
Or you don't subclass Thread and pass a target. But that target must be
a function. You don't pass a function, you call it!!
Look at this:
Thread(target=tcpip.tcpip)
Note the missing parentheses!
Apart from that, you should seriously consider applying a consistent
naming style to your code.
