我在使用python 3运行os.execl（）时遇到问题

import os import sys

pid = os.fork()
print ("second test")
if pid == 0:
    print ("this is the child")
    print ("I'm going to exec another program now")
    os.execl("python", "test.py", * sys.argv)
else:
    print ("the child is pid %d" % pid)
    os.wait()

我到处都看过示例，但是对于我自己的一生，我什至无法理解。我以为这样可以，但是出现了这个错误：

Traceback (most recent call last):
  File "main.py", line 9, in <module>
    os.execl("python", "test.py", * sys.argv)
  File "/usr/local/lib/python3.8/os.py", line 534, in execl
    execv(file, args)
FileNotFoundError: [Errno 2] No such file or directory
