You must expilicitly ask your shell to do exit if something fails.  Like this:

~~~~~ shellTest.sh ~~~~~~~
#!/bin/bash
set -e
python test.py
python second.py
~~~~~~~~~~~~~~~~~~~~~~~

I explicitly set the shell to /bin/bash on the shebang line, and then
set the -e option to fail when a command exits with a non-zero status.

You should always have a shebang line in your shell files, and execute
them as ./shellTest.sh  (after chmod +x shellTest.sh); moreover, one
for Python files is recommended, like this: #!/usr/bin/env python
