Why do I need to use pip3 but not pip

[Arup Rakshit]

Hello All,

Thanks I got it now.

One related question: Can I use pip3 for example to install packages project specific, but not globally? So that when I delete the project, all of them gone also from my disk. 

Thanks,

So python 3 is installed as the "python3" command to avoid confusion.  The "pip" command from your python 3 install looks like it is also installed as "pip3" to avoid confusion.
