How do i pass an array jobs to the function lsb_forcekilljob to be killed?

Passing an array job, lsf.lsb_forcekilljob(337400[4]) throws the following error:
Traceback (most recent call last):
File "/data/cmetrics/lsf_test.py", line 64, in
lsf.lsb_forcekilljob(337400[4])
TypeError: 'int' object has no attribute 'getitem'

Also how do i pass a group of jobs to be killed at once?
