What’s the difference between pip and pip3?

What’s the difference between pip and pip3? Pip is for python version less than 3. and pip3 is used when you want to install packages for python version 3 or higher.

The text about is right in most of cases. The packages’ installation location is different for pip and pip3. But sometimes, the pip command in bash is a soft-link to pip3, if you want to check whether your env is this case, just use which pip and which pip3 command to see the unix executable.
