Pip can't be run and apt-get command not found

I've just recently gotten back into learning more about software going into django. It required me to install some packages, but I found out my pip wouldn't work. So I thought I had to reinstall it or something since this worked previous so I attempted a Sudo apt-get --update but then I got the error that apt-get command wasn't found. I scoured the internet for answers of this issue and I haven't found one that had this issue.

This is my error pip is giving me.

Traceback (most recent call last):

I've attempted to see if I can reinstall sudo or pip but same issue.

Simple code like: apt-get install sudo apt-get pip

I was hoping I would get a short response complaining that I didn't complete my lines or something is missing, but pip is giving me this strange error.

Solution

Thanks for the comments. The issue was a bit more complicated but I managed to get an idea of my issue after checking the comments under the question. Apparently my pip was missing 19.0.3 files and I had to manually install them to get the required files.

easy_install pip==19.0.3

I had to use the easy_install method to get around the pip command.
