PYTHON TO 2.7.3 TO 2.7.9 INSTALL

I want to change or remove this version and I want to install Python version 2.

By default Python 3 is installed on my Pi. I would like to work on Python 2 not Python 3. There is also python3 installed on many machines, so you can do: python3 -version I am new to the Raspberry Pi, I have a project. Prints the Python version number of the executable and exits. Manual/manpages also available for most of such CLI which can be displayed by man (Ex: man python) You can find a list of options/parameters for many commands in the terminal by typing the command followed by -help Type following in the terminal ( Ctrl+ Alt+ T): python -V It's obviously a pretty hideous command but this is again real output and it seems to have done a fairly thorough job. I heard that installing 2.7.9 over 2.7.3 causes the OS to explode as some OS dependencies require 2.7. srv/chroot/trusty_i386/usr/bin/python3.4m: Python 3.4.0 The default Python install is version 2.7.3. media/ned/websites/venvold/bin/python: Python 2.7.4 In this DigitalOcean article, we are going to talk about downloading and setting up Python (versions 2.7.6 and 3.3.3) without breaking the system's default 2.6 (or 2. If we assume that a Python binary is always going to be called python and be a binary file, we can just search the entire system for files that match those criteria: $ sudo find / -type f -executable -iname 'python*' -exec file -i '' | xargs readlink -f | sort -u | xargs -I % sh -c 'echo -n '%: ' % -V' The fact is there could be hundreds of different versions of Python secreted around your system, either on paths that are contextually added, or living under different binary names (like python3). If we were in a Virtualenv (a common Python stack management system) python might resolve to a different version: $ readlink -f $(which python) | xargs -I % sh -c 'echo -n '%: ' % -V' We can chain this in to show the version of that version of Python: $ readlink -f $(which python) | xargs -I % sh -c 'echo -n '%: ' % -V'Д«ut this is still only telling us what our current python resolution is. In default cases in 14.04 this will simply point to /usr/bin/python2.7. In Ubuntu we can check the resolution with readlink -f $(which python). But to see every version of python in your system takes a bit more. You can use python -V (et al.) to show you the version of Python that the python command resolves to.
