Disable/Enable OSB proxy service via WLST

Question

I'm trying to automate one of the OSB proxy service using WLST in one of our environments and when i checked with Oracle support they routed me to this 3rd party python script which was tried by by others successfully long time back but since i'm new to this Python script, i'm having hard time. So wanted to see if someone can help me with correcting this script and fixing the issues. Provided below is the command i'm trying to disable/enable the OSB proxy service along with the whole script.

. ./setDomainEnv.sh (ran command to set the domain environment)

/appl/oracle/middleware/wls/12.2.1.4/oracle_common/common/bin

[xxxxxx@xxxxxxx bin]$ ./wlst.sh setproxystate.py -e t3://xxxxx:7002 xxxxxx project/proxyname
