Dear Python Experts Team, As am newbie to python development, I am trying to use the below function to get verify the filesystem type of the SD card parition using bash command in python using subprocess module, I ma seeing the below Error "SyntaxError: can't assign to literal" *CODE:* *====* import helper from os import path import subprocess import os import otg_ni class emmc(object): """ emmc getters and setters info: https://www.kernel.org/doc/Documentation/cpu-freq/user-guide.txt """ def __init__(self): self._helper = helper.helper() self._otg_ni = otg_ni.otg_ni() *def get_fstype_of_mounted_partition(self, fs):* """ Get the filesystem type of the mounted partition. :partition_name : Partition path as string (e.g. /dev/mmcblk0p1) :return: filesystem type as string or None if not found """ * cmd = "blkid -o export %s | grep 'TYPE' | cut -d"=" -f3" % (fs)* *return self._helper.execute_cmd_output_string(cmd)* *def execute_cmd_output_string(self, cmd, enable_shell=False):* """ Execute a command and return its output as a string. :param cmd: abs path of the command with arguments :param enable_shell : force the cmd to be run as shell script :return: a string.
