when I RUN THIS code on win7:

import serial
import scanwin32

def get_available_coms():
    avail = []
    for order, port, desc, hwid in sorted(scanwin32.comports()):
        if port.startswith('COM'):
            avail.append("%s" % port)
    return avail

get_available_coms()

error occurs:

Error:Traceback (most recent call last):
  File "D:/software data/pycharm projects/test180425/serial-2.py", line 3, in <module>
    import serial.tools.list_ports
