Does a package also gets installed in conda environment if I use pip to install packages not included in Anaconda?
Before you start installing packages, you should decide on how you want to manage your packages for different projects. I'd recommend that you create a dedicated conda environment for each project. Then you have to activate the respective environment whenever you want to work on a project. But packages installed for one project don't interfere with those for another. It helps to install Miniconda rather than Anaconda, because that keeps the conda base environment clean.
You write that you're used to calling pip install, but you don't mention Python virtual envs nor conda environments. That sounds as if you're typically installing packages globally on your machine. Sooner or later, that's going to create a mess.
If you decide to use conda environments, you have to remember to always activate the environment for your project before installing packages for that project. Then both pip install and conda install will put packages into that environment. When I have a choice, I prefer to install packages with conda from its default channels. conda has better dependency management than pip, and conda can handle non-Python dependencies. But packages sometimes have different names in conda and pip, so it might be extra effort to translate installation instructions for pip into similar commands for conda.
I am currently working on a Django project and want to install an additional Django (app) package called "tinymce". I've installed Anaconda just recently and I'm not used to commands related to conda. I often used to pip install packages from the command prompt. But now I'm really confused if I really should just use the same pip install or use some other conda commands (if there are any) to install that package. Also, does that affect anything, if I am to frequently use that packages? 
FYI: I'm on Windows & using Python 3.7 using the recent Anaconda release.
