Installing Python Dependancies Using requirements.txt

I come from PHP land where you can use PHP Composer to install dependencies automatically. Glad to figure out how to use Python's version with the requirements.txt. I wish that tutorials would put this at the beginning.

pip3 freeze

then, I copied out all the dependancies that I had installed myself and put them in my requirements.txt file at the base of your project (like the composer.json). Here is a sample of my requirements.txt

Django==4.0.4
django-browser-reload==1.3.0
django-light==0.1.0.post3
django-taggit==2.1.0
django-tailwind==3.1.1
mysqlclient==2.1.0
Pillow==9.1.0
django-environ==0.8.1

pip3 install -r requirements.txt

I store my .env-sample file in my /mysite directory. So, next I need to copy that file and then put in the environment variable settings. Then I am ready to run the local server.
