#!/usr/bin/env python2
t1=Thread(target=myfunction, args=('MyStringHere',))
t2=Thread(target=myotherfunction, args=('MyOtherStringHere',1,10))
t1.start();t2.start();
t1.join();t2.join()

is equivalent to

#!/bin/bash
myfunction MyStringHere & P1=$!
myotherfunction MyStringHere 1 10 & P2=$!
wait $P1; wait $P2
