如何删除python3中的b符号

Question

如何从python3脚本中删除b符号？

import subprocess

get_data=subprocess.check_output(["df -k | awk '{print $6}'"],shell=True)
data_arr=get_data.split()
data_arr.pop(0)
data_arr.pop(0)
for i in data_arr[:]:
    print(str(i))

输出

b'/dev/shm'
b'/run'
b'/sys/fs/cgroup'
b'/'
b'/tmp'
b'/test'
b'/boot'
b'/home'
b'/var'
b'/mnt/install'
