Python脚本在Thonny中运行，但在终端中出现错误

Question

当我在Thonny IDE中手动运行脚本时，我能够让它工作，但是我不能在终端窗口中触发它

sudo python /home/pi/myscript.py

我收到这个错误：

Traceback (most recent call last):
  File "/home/pi/myscript.py", line 14, in <module>
    MESSAGE1_B = bytes(MESSAGE1, 'utf-8')
TypeError: str() takes at most 1 argument (2 given)

我的代码如下：

import RPi.GPIO as GPIO # Import Raspberry Pi GPIO library
import time

GPIO.setwarnings(False) # Ignore warning for now
GPIO.setmode(GPIO.BOARD) # Use physical pin numbering
GPIO.setup(10, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # Set pin 10 to be an input pin and set initial value to be pulled low (off)
GPIO.setup(26, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # Set pin 26 to be an input pin and set initial value to be pulled low (off)

import socket

UDP_IP = "10.1.10.149"
UDP_PORT = 50005
MESSAGE1 = "$ Channel 1 Thru 5 @ FULL #"
MESSAGE1_B = bytes(MESSAGE1, 'utf-8')
MESSAGE2 = "$ Channel 1 thru 5 @ 0 #"
MESSAGE2_B = bytes(MESSAGE2, 'utf-8')

print("UDP target IP: %s" % UDP_IP)
print("UDP target port: %s" % UDP_PORT)
print("message: %s" % MESSAGE1)
print("message: %s" % MESSAGE2)


while True: # Run forever
    if GPIO.input(10) == GPIO.HIGH:
        sock = socket.socket(socket.AF_INET, # Internet
                     socket.SOCK_DGRAM) # UDP
        sock.sendto(MESSAGE1_B, (UDP_IP, UDP_PORT)) #
        
        time.sleep(0.5)
        
    if GPIO.input(26) == GPIO.HIGH:
        sock = socket.socket(socket.AF_INET, # Internet
                     socket.SOCK_DGRAM) # UDP
        sock.sendto(MESSAGE2_B, (UDP_IP, UDP_PORT)) #
        
        time.sleep(0.5)

有人能帮我弄清楚是怎么回事吗？请谢谢你。

“您的代码似乎运行了两个不同的Python版本- 3.x在Thonny，2.x在终端。

使用python3 /home/pi/myscript.py

我也有类似的问题，直到我用了和Thonny一样的Python
