I know there are other posts here asking how to install python 3.6, but all I want is a version of python 3. The repos seem to have python 3.4, which is fine but the problem is that apt-get is not responding in a way that makes sense. When I try the command apt-get install python3 I get the response:



python3 is already the newest version.


This is despite the fact that python -V command tells me python is 2.7.9. How do I install python 3 please?




debian apt python3

The default python interpreter is Python 2. If you want to run Python 3, you need to use the command python3. I would expect running python3 -V would give you Python 3.4.x.

    The tow version of python is already installed on your system , to list them :



     update-alternatives --list python


    sample output:



    /usr/bin/python2.7
    /usr/bin/python3.5


    To set python3 as default run:



    update-alternatives --config python


    Choose python 3.5

                      How many registers does an x86_64 CPU actually have?

                      Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
