On Ubuntu, how do you install a newer version of python and keep the older python version?
- by Trevor Boyd Smith
Background:
I am using Ubuntu
The newer python version is not in the apt-get repository (or synaptic)
I plan on keeping the old version as the default python when you call "python" from the command line
I plan on calling the new python using pythonX.X (X.X is the new version).
Given the background, how do you install a newer version of python and keep the older python version?
I have downloaded from python.org the "install from source" *.tgz package. The readme is pretty simple and says "execute three commands: ./configure; make; make test; sudo make install;"
If I do the above commands, will the installation overwrite the old version of python I have (I definitely need the old version)?
