Ability to freeze directly installed packages without their dependencies

[DarkSuniuM]

What's the problem this feature will solve?
Get a list of packages I installed directly and they havn't installed as dependency.

For example:

$ pip install flask
#...
Installing collected packages: itsdangerous, MarkupSafe, Jinja2, Werkzeug, click, flask
Successfully installed Jinja2-2.11.2 MarkupSafe-1.1.1 Werkzeug-1.0.1 click-7.1.2 flask-1.1.2 itsdangerous-1.1.0

Installing Flask, made multiple dependencies of flask, installed, Perfect.

$ pip freeze
click==7.1.2
Flask==1.1.2
itsdangerous==1.1.0
Jinja2==2.11.2
MarkupSafe==1.1.1
Werkzeug==1.0.1

but there is no way for me to only get the Flask package in my pip freeze command which I installed directly by myself.

Describe the solution you'd like
Having a flag like --intentionally or even having this behavior as default and a flag for getting dependencies as well would be awesome, I'll explain why.

Additional context
This can be a huge help on #5823, Even if #5823 gets implemented, still, people using pip freeze > requirements.txt will list all dependencies, and when someone does a pip install -r requirements.txt, All packages, including the dependencies listed in requirements.txt, will be installed as top-level by their own.

Ops,
Seems like it's a duplicate of #6344

Hi DarkSuniuM, I recommend you using a new virtual environment every time you create a new project.
Reason
a) When you pip install ---- python install that dependencies for your complete python in your system. But when you will use a virtual environment and then you will install the dependencies and pip freeze it will show only that you have only used for that project. Then pip freeze will use only the dependencies that you have used for your specific project.

Hi there

Which part of this topic made you think I'm using same env or global site-libs for all of my projects? xD
