Probably I understood it not correctly. What did you mean was to put
that code into my python script "shrink_bs_070226.py" and then calls
script itself?

So I took my script "shrink_bs_070226.py" and it starts with:
**********************************
#!/usr/bin/env python
import sys, re, glob, shutil
import os

then I put your code in that script

if os.environ["LD_LIBRARY_PATH"].count('/path/Linux/rh_linux') !=1:
   os.environ["LD_LIBRARY_PATH"]=os.environ["LD_LIBRARY_PATH"]+':'+'/
path/Linux/rh_linux'
   os.system("shrink_bs_070226.py")
   raise SystemExit

and here continues my script:

from qt import *

.....
***********************

Is it correct?

BTW: On lines 3:18 I have comments, script description and
modifications, therefore is "from qt import *" on the line 29
