```python
import time
from machine import Pin
import rtthread
import utime
import _thread

lock = _thread.allocate_lock()

def pin_num(pin_index):
    """
    Get the GPIO pin number through the GPIO index, format must be "P + <A~K> + number", such as PE7
    """

if pin_index[0] != 'P':
        print("ERROR : Please pass in the correct parameters P + <A~K> + number, such as PE7")
        return

if not pin_index[1].isupper():
        print("ERROR : Please pass in the correct parameters P + <A~K> + number, such as PE7")
        return

return (ord(pin_index[1]) - ord('A')) * 16 + int(pin_index[2:])

led1 = Pin(("led_red", pin_num("PG2")), Pin.OUT_PP)
led2 = Pin(("led_red", pin_num("PD3")), Pin.OUT_PP)
led3 = Pin(("led_red", pin_num("PD4")), Pin.OUT_PP)
led4 = Pin(("led_red", pin_num("PD5")), Pin.OUT_PP)

def led1_thread(time_):
    led1_status = True
    while True:
        print("led1\r\n")
        led1.value(led1_status)
        led1_status = not(led1_status)
        utime.sleep(time_)

def led2_thread(time_):
    led2_status = True
    while True:
        print("led2\r\n")
        led2.value(led2_status)
        led2_status = not(led2_status)
        utime.sleep(time_)

def led3_thread(time_):
    led3_status = True
    while True:
        print("led3\r\n")
        led3.value(led3_status)
        led3_status = not(led3_status)
        utime.sleep(time_)

def led4_thread(time_):
    led4_status = True
    while True:
        print("led4\r\n")
        led4.value(led4_status)
        led4_status = not(led4_status)
        utime.sleep(time_)

_thread.start_new_thread(led1_thread, (1,))
_thread.start_new_thread(led2_thread, (2,))
_thread.start_new_thread(led3_thread, (3,))
_thread.start_new_thread(led4_thread, (4,))  #
```

以上是在stm32f427测试RTThread-MicroPython多线程的脚本，
第一次运行脚本后，使用exit()退出。
第二次使用“python”命令再次进入后就没有任何反应了。
请问一下谁知道是什么原因呢？谢谢
