Is it possible to install Python 2.5 in 11.04?

Launchpad has a topic about this.

Here is a tutorial on installing python 2.5 on Ubuntu 10.10. 11.04 should be identical for this.

From that websites the commands would be:

sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python2.5

Executing python2.5 file at commandline would execute 'file' with v2.5. python file would use the newest version.

I only used this once roughly a year ago so be wary of pitfalls.
