python - pyserial works in repl but not script -


i'm attempting write data arduino using pyserial on windows. however, i've run bit of snag can't seem figure out. can run:

>>> import serial >>> ser = serial.serial('com3',9600) >>> ser.write(b'0')

and works fine on repl not when run in script. entirity of script text being:

import serial   if __name__=="__main__":     ser = serial.serial('com3',9600)     print("yes, being called")     ser.write(b'0')
