First question:
which python though its usually /usr/bin/python for the 2.7
Second question:
From a terminal & python2.7: python2.7 yourfile.py.
Simailarly for 3.2: python3.2 yourfile.py though 3.2 isn't installed by default. (You can apt-get install python3.2.)
What python yourfile.py will do depends on which alternative is used for your python interpreter. You can change that by issuing update-alternatives python as root (or by using su).
Third question:
Environment variables are shell dependent, though you can write them out with echo $variable and set them with variable=value (from bash). The search path is simply called PATH and you can get yours by typing echo $PATH.
I hope this was helpful.

If you want to find the location of a program you can just use whereis <program>.
In your case run:
whereis python2.7
whereis python3.2
For finding every file that apt-get has copied for installation use:
dpkg -S python2.7
dpkg -S python3.2
But maby it is recommend to save it in a textfile, because the output is to large.
dpkg -S python2.7 >log.txt
gedit log.txt
for running .py file with python 3.2
python3.2 <file.py>
How do I install pip for the new Python version?
How do I make the new Python version the default?
Does Ubuntu 24.04 include pip by default?
You can type which python on the ubuntu terminal and it will give the Python installed location path.
First, I hope you don't really set PYTHONPATH=/etc, /etc is for configuration files, not python libraries.
You can see what an environment variable is set to by using echo, e.g.: echo $PYTHONPATH. If the variable has not been set it will be blank. You can also use env to get a list of all environment variables, and couple with grep to see if a particular one is set, e.g. env | grep PYTHONPATH.
