Syntax problem in mlag_data_compare.py

[tcomerma]

I've tried the script on exos 32.4.1.5 and it doesn't work

I'm getting a syntax error

# run script mlag_data_compare.py
###############################
MLAG peer is {0}
Traceback (most recent call last):
  File "/usr/local/cfg/mlag_data_compare.py", line 104, in <module>
    main()
  File "/usr/local/cfg/mlag_data_compare.py", line 80, in main
    print ("MLAG peer is {0}").format(peer_info['peerName'])
AttributeError: 'NoneType' object has no attribute 'format'

The problem seems to be parenthesis placement. The .format() method is being called on the result of print(), not on the string itself. Changing it to

print("MLAG peer is {0}".format(peer_info['peerName']))

Solves the issue.

Affected lines in the code:

• Line 68: print ("MLAG peer is {0}").format(peer_info['peerName'])
• Line 75: print ("ISC port {0}").format(isc_port)
• Line 79: print ("{0} : {1} : {2}").format(isc_vlans['VlanName'],isc_vlans['VlanId'],isc_vlans['tag'])
• Line 84: print ("MLAG Port {0}, ID: {1}, Rpeer : {2}").format(port['port'], port['idx'], port['remoteportstate'])
• Line 86: print ("{0} : {1} : {2}").format(mvlan['VlanName'],mvlan['VlanId'],mvlan['tag'])

Thanks for the script !
