Yes, sure, you can set environment variables...

...but this won't work, I'm afraid.

LD_LIBRARY_PATH is for the program loader / dynamic linker under Linux. This
thing is what is invoked _before_ the program is started, any later
modifications to the environment are ignored.

Similarly PATH, which tells the shell (e.g. bash) where to find executables.
If you need that to e.g. find 'python' itself, you're out of luck.
Otherwise, I believe Python itself doesn't use PATH, so you could set it
inside and any shells started from Python should pick it up.
