No. I'm not entirely sure that is a good idea! No, not all.

'scl enable python27 bash' creates a *new* shell with the correct
environment.  As each invocation of bash reads .bashrc, it will also
create another new shell which will then read .bashrc and create
another shell ....  

Depending on the speed of your machine and disks and how much memory
you have, it will take a few seconds to a few minutes to grind your
machine to a halt.
