Make sure, you have the right port selected. You have to import the libaries first. To do this go to cmd and enter "pip install serial". After this you also have to import the other libaries! ("pip install time"; "pip install os")

2import serial         #to install type 'pip install serial'  in cmd
3import time           #to install type 'pip install time' in cmd

5#import pyttsx3    #not  necessary only if you want(for sound)
