Messed up pip install

I was just trying to install pip some months ago, I recall. However, I've had no use of it till date. I recall visiting this site and going on with the command curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py. I can also verify this as I have get-pip.py in my ~. Then I also remember reading "pip is already installed if you are using Python 2 >=2.7.9 or Python 3 >=3.4 downloaded from python.org or if you are working in a Virtual Environment created by virtualenv or pyvenv. Just make sure to upgrade pip."

I obviously had Python installed, so I can remember running pip install -U pip and it installing the latest version, but I don't remember if I ever ran sudo python get-pip.py before reading the above(it is supposed to be run if you don't have python already installed). I don't remember it but I think I did, because I have these files:

• easy_install
• easy_install-2.7
• pip
• pip2
• pip2.7
• wheel

in /usr/local/bin with the same modified date as that of get-pip.py in my home directory.

Now when I run pip install -U pip, it returns Requirement already up-to-date: pip in /usr/local/lib/python2.7/dist-packages (10.0.1)

I'm just trying to clean my system of unwanted stuff and want to get rid of this extra installation I did(if I did it). How do I proceed with it? Thanks in advance!
