python - Not getting LD_LIBRARY_PATH -


i amending existing script in want check set of libraries used in executable shared libraries called @ run time. have list of libraries need compare shared libraries. getting shared libraries trying ld_library_path giving below code had no luck. tried checking variable on command line giving 

echo $ld_library_path

and returned /opt/cray/csa/3.0.0-1_2.0501.47112.1.91.ari/lib64:/opt/cray/job/1.5.5-0.1_2.0501.48066.2.43.ari/lib64

the things have tried (this python script) 

#! /usr/bin/python -e import os     ld_lib_path = os.environ.get('ld_library_path')     #ld_lib_path = os.environ["ld_library_path"]

i think missing print in script? works me command line:

python -c 'import os; temp=os.environ.get("ld_library_path"); print temp'

script:

#! /usr/bin/python -e import os ld_lib_path = os.environ.get('ld_library_path') print ld_lib_path
