here is the sample code :

#!/usr/bin/env python

# Sample Python client accessing JIRA via SOAP. By default, accesses
# http://jira.atlassian.com with a public account. Methods requiring
# more than basic user-level access are commented out. Change the URL
# and project/issue details for local testing.
#
# Note: This Python client only works with JIRA 3.3.1 and above (see
# http://jira.atlassian.com/browse/JRA-7321)
#
# Refer to the SOAP Javadoc to see what calls are available:

import SOAPpy, getpass, datetime

soap = SOAPpy.WSDL.Proxy('http://jira.company.com:8080/rpc/soap/jirasoapservice-v2?wsdl')


jirauser='username'
passwd='password'

# This prints available methods, but the WSDL doesn't include argument
# names so its fairly useless. Refer to the Javadoc URL above instead
#print 'Available methods: ', soap.methods.keys()

def listSOAPmethods():
    for key in soap.methods.keys():
        print key, ': '
        for param in soap.methods[key].inparams:
            print '\t', param.name.ljust(10), param.type
        for param in soap.methods[key].outparams:
            print '\tOut: ', param.name.ljust(10), param.type


auth = soap.login(jirauser, passwd)

issue = soap.getIssue(auth, 'QA-79')
print "Retrieved issue:", issue

print "Done!"


The complete error is as follows , in order to provide the complete context:

I changed the JIRA Python CLI code to use suds instead of SOAPpy a while ago and haven't looked back. SOAPpy is pretty old and seems unsupported now.
i am getting error "no schemaLocation attribute in import" when using Python client accessing JIRA via SOAP
