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.
"""
try:
result = subprocess.check_output(split(cmd),
stderr=subprocess.STDOUT,
shell=enable_shell)
except subprocess.CalledProcessError as e:
s = """While executing '{}' something went wrong.
Return code == '{}'
Return output:\n'{}'
""".format(cmd, e.returncode, e.output, shell=enable_shell)
raise AssertionError(s)
return result.strip().decode("utf-8")
*if __name__ == "__main__":*
m = emmc()
* m.get_fstype_of_mounted_partition("/dev/mmcblk0p1")*
*Error:*

Kindly do the needful as early as possible, as am stuck with this issue
from past 2 days no clues yet, please redirect me to the correct forum if
this is not the right place for pasting python related queries
Many Thanks in advance,
