[Tutor] What potential problems might I encounter installing Anaconda?

[boB Stepp]

Currently I have one version of Python installed, v. 3.4.4.  My OS is
W7-64bit.  I use Vim 7.4 for my editing.  Two of the textbooks I have
started will use several Python scientific computing packages.
Anaconda seems the way to go to get them all (plus others) in one fell
swoop.  Questions:

1) At this time I have no need for multiple versions of Python on my
home PC.  Would it be advisable for me to uninstall my existing v.
3.4.4 as the Anaconda distribution I am looking at uses v. 3.5?

2) Will installing Anaconda cause any problems with my existing Vim
7.4 installation?  At this stage of my learning, I have not installed
any Python-related plugins in Vim.  However, I do value the existing
syntax highlighting Vim does for Python out of the box.  Will I need
to reinstall Vim after installing Anaconda for Vim to be able to find
Python?

3) Is there anything else I need to be aware of regarding Anaconda?

4) I have only tonight started looking into this.  My initial
impression is that updates and new Python package installations are
done in Anaconda with a "conda" command.  Does this mean that pip
installations can no longer be done?

TIA!
Happy New Year!
