How to collect scsi-id and Device name?

# Note: SCSI-ID 0:0:0:0 is known to the kernel as sda

import os

sd ={}
dr = '/sys/bus/scsi/drivers/sd'
for i in os.listdir(dr):
    if ":" in i:
        sd[i] = os.listdir(dr+'/'+i+'/block')[0]
print('{:<15} {}'.format("SCSI-ID","Device-Name"))
print('*'.ljust(27,'*'))
for j in sd:
    print('{:^8} {:^22}'.format(j,sd[j]))
