Dear Python Experts, As still I am newbie and learning python, I am trying to reuse the Bluetoothctl wrapper in Python from the link ( https://gist.github.com/egorf/66d88056a9d703928f93) I am using python3.6 version, In pycharm editor on the bold highlighted code snippets I see the error message "Python version 3.6 does not support this syntax.",
Could you please how help me how the below highlighted lines of code can be can be ported to python3.6 version? * except BluetoothctlError, e:* * print(e)* * return None* Full Code snippet: ============== import time import pexpect import subprocess import sys class BluetoothctlError(Exception): """This exception is raised, when bluetoothctl fails to start.""" pass class Bluetoothctl: """A wrapper for bluetoothctl utility.""" def __init__(self): out = subprocess.check_output("rfkill unblock bluetooth", shell = True) self.child = pexpect.spawn("bluetoothctl", echo = False) def get_output(self, command, pause = 0): """Run a command in bluetoothctl prompt, return output as a list of lines.""" self.child.send(command + "\n") time.sleep(pause) start_failed = self.child.expect(["bluetooth", pexpect.EOF]) if start_failed: raise BluetoothctlError("Bluetoothctl failed after running " + command) return self.child.before.split("\r\n") def start_scan(self): """Start bluetooth scanning process.""" try: out = self.get_output("scan on") * except BluetoothctlError, e: print(e) return None* def make_discoverable(self): """Make device discoverable.""" try: out = self.get_output("discoverable on") * except BluetoothctlError, e: print(e) return None* def parse_device_info(self, info_string): """Parse a string corresponding to a device.""" device = {} block_list = ["[\x1b[0;", "removed"] string_valid = not any(keyword in info_string for keyword in block_list) if string_valid: try: device_position = info_string.index("Device") except ValueError: pass else: if device_position > -1: attribute_list = info_string[device_position:].split(" ", 2) device = { "mac_address": attribute_list[1], "name": attribute_list[2] } return device def get_available_devices(self): """Return a list of tuples of paired and discoverable devices.""" try: out = self.get_output("devices") * except BluetoothctlError, e: print(e) return None* else: available_devices = [] for line in out: device = self.parse_device_info(line) if device: available_devices.append(device) return available_devices def get_paired_devices(self): """Return a list of tuples of paired devices.""" try: out = self.get_output("paired-devices") * except BluetoothctlError, e: print(e) return None* else: paired_devices = [] for line in out: device = self.parse_device_info(line) if device: paired_devices.append(device) return paired_devices def get_discoverable_devices(self): """Filter paired devices out of available.""" available = self.get_available_devices() paired = self.get_paired_devices() return [d for d in available if d not in paired] def get_device_info(self, mac_address): """Get device info by mac address.""" try: out = self.get_output("info " + mac_address) * except BluetoothctlError, e: print(e) return None* else: return out def pair(self, mac_address): """Try to pair with a device by mac address.""" try: out = self.get_output("pair " + mac_address, 4) * except BluetoothctlError, e: print(e) return None* else: res = self.child.expect(["Failed to pair", "Pairing successful", pexpect.EOF]) success = True if res == 1 else False return success def remove(self, mac_address): """Remove paired device by mac address, return success of the operation.""" try: out = self.get_output("remove " + mac_address, 3) * except BluetoothctlError, e: print(e) return None* else: res = self.child.expect(["not available", "Device has been removed", pexpect.EOF]) success = True if res == 1 else False return success def connect(self, mac_address): """Try to connect to a device by mac address.""" try: out = self.get_output("connect " + mac_address, 2) * except BluetoothctlError, e: print(e) return None* else: res = self.child.expect(["Failed to connect", "Connection successful", pexpect.EOF]) success = True if res == 1 else False return success def disconnect(self, mac_address): """Try to disconnect to a device by mac address.""" try: out = self.get_output("disconnect " + mac_address, 2) * except BluetoothctlError, e: print(e) return None* else: res = self.child.expect(["Failed to disconnect", "Successful disconnected", pexpect.EOF]) success = True if res == 1 else False return success kindly do the needful, Many Thanks in advance, _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
