I want to download the Python on my Ubuntu 12.04, but I run it on USB flash drive. Do I have any choice to let the Python download on my flash drive? FYI it is my first time touching Ubuntu so try to make it simple.
If you want to run python in Ubuntu, just open a terminal with Ctrl-Alt-T and execute this command
Then you will have an interactive python interpreter running in the termnal.
I am assuming you want to run python portably from the USB drive and use it anywhere with Linux system. You can achieve this by downloading portable python from this site
Enjoy Portable Pythonning!!
