python - Python线程参数数量错误

Question

很简单的代码：

import threading

def test(word):
    print(word)

threading.Thread(target = test, args = "hello").start()

我收到以下错误：

Exception in thread Thread-1:
Traceback (most recent call last):
  File "C:\Users\phil\AppData\Local\Programs\Python\Python39\lib\threading.py", line 950, in _bootstrap_inner
    self.run()
  File "C:\Users\phil\AppData\Local\Programs\Python\Python39\lib\threading.py", line 888, in run
    self._target(*self._args, **self._kwargs)
TypeError: test() takes 1 positional argument but 4 were given

给定的 4 个参数是单词“hello”中的字母数。这是我不明白的，因为“你好”这个词只是一个论点。如果我用“A”替换“hello”，它会起作用，因为“A”只是一个字母。

import threading

def test(word):
    print(word)

threading.Thread(target=test, args=("hello",)).start()
