CodePudding user response：

Pass a parameter to your Thread objects to act as a per-thread offset:

def test(offset):
    for i in range(10):
        print(str(offset   i   1)   "    Hello world")

t1 = Thread(test, args=(0,))
t2 = Thread(test, args=(10,))

t1.start()
t2.start()

Use a single Thread with a range of 20 ...

>>> def test():
...     for i in range(20):
...         print(str(i 1) "     Hello world")
...
>>> t1=Thread(target=test)
>>> t1.start()
