Listing available com ports with Python

一行解决方案与 pySerial 软件包。

python -m serial.tools.list_ports

试试这个代码

import serial.tools.list_ports
for i in serial.tools.list_ports.comports():
print(i)

它回来了

COM1 - Port de communication (COM1)
COM5 - USB-SERIAL CH340 (COM5)

如果您只是不知道例如 COM1的端口名称

import serial.tools.list_ports
for i in serial.tools.list_ports.comports():
print(str(i).split(" ")[0])

它回来了

COM1
COM5

就像我的情况一样 Py 3.764位

只适用于 Windows:

import winreg
import itertools


def serial_ports() -> list:
path = 'HARDWARE\\DEVICEMAP\\SERIALCOMM'
key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, path)


ports = []
for i in itertools.count():
try:
ports.append(winreg.EnumValue(key, i)[1])
except EnvironmentError:
break


return ports


if __name__ == "__main__":
ports = serial_ports()

可能会迟到，但可能会帮助需要帮助的人。

import serial.tools.list_ports




class COMPorts:


def __init__(self, data: list):
self.data = data


@classmethod
def get_com_ports(cls):
data = []
ports = list(serial.tools.list_ports.comports())


for port_ in ports:
obj = Object(data=dict({"device": port_.device, "description": port_.description.split("(")[0].strip()}))
data.append(obj)


return cls(data=data)


@staticmethod
def get_description_by_device(device: str):
for port_ in COMPorts.get_com_ports().data:
if port_.device == device:
return port_.description


@staticmethod
def get_device_by_description(description: str):
for port_ in COMPorts.get_com_ports().data:
if port_.description == description:
return port_.device




class Object:
def __init__(self, data: dict):
self.data = data
self.device = data.get("device")
self.description = data.get("description")




if __name__ == "__main__":
for port in COMPorts.get_com_ports().data:
print(port.device)
print(port.description)


print(COMPorts.get_device_by_description(description="Arduino Leonardo"))
print(COMPorts.get_description_by_device(device="COM3"))

一些简单的东西，但我使用它很多。

import serial.tools.list_ports as ports


com_ports = list(ports.comports()) # create a list of com ['COM1','COM2']
for i in com_ports:
print(i.device) # returns 'COMx'

需要注意的是，这样的代码:

for i in serial.tools.list_ports.comports():
print(i)

返回以下资料:

COM7 - Standard Serial over Bluetooth link (COM7) COM1 - Communications Port (COM1) COM8 - Standard Serial over Bluetooth link (COM8) COM4 - USB-SERIAL CH340 (COM4)

如果您希望按顺序列出端口，并且只列出可用的端口，请尝试: (归功于 tfeldmann)

   def serial_ports():
""" Lists serial port names


:raises EnvironmentError:
On unsupported or unknown platforms
:returns:
A list of the serial ports available on the system
"""
if sys.platform.startswith('win'):
ports = ['COM%s' % (i + 1) for i in range(256)]
elif sys.platform.startswith('linux') or sys.platform.startswith('cygwin'):
# this excludes your current terminal "/dev/tty"
ports = glob.glob('/dev/tty[A-Za-z]*')
elif sys.platform.startswith('darwin'):
ports = glob.glob('/dev/tty.*')
else:
raise EnvironmentError('Unsupported platform')


result = []
for port in ports:
try:
s = serial.Serial(port)
s.close()
result.append(port)
except (OSError, serial.SerialException):
pass
return result

这将返回以下结果:

['COM1', 'COM4', 'COM8']

因此，与第一个例子中的结果是[‘ COM7’，‘ COM1’，‘ COM8’，‘ COM4’]不同，这次我按顺序得到了所有的 com 端口，并且只有那些可用的端口。如果你需要的话非常方便，可以测试看看是否有。
