"E: Unable to locate package python-pip" on Ubuntu 18.04

I am trying to install virtualenv on Ubuntu. First it said command 'pip' not found, so I typed sudo apt install python-pip then it said E: Unable to locate package python-pip I tried to reset WSL, download using cmd but it doesn't work with Ubuntu. I don't know why. Even though I have downloaded python3, virtualenv, and pip using cmd. It doesn't work with Ubuntu 18.04. It also fails on Ubuntu 14.04. aiki@LAPTOP-886AEJJG:~$ pip Command 'pip' not found, but can be installed with: sudo apt install python-pip aiki@LAPTOP-886AEJJG:~$ sudo apt install python-pip [sudo] password for aiki: Reading package lists...
