• from pydantic import BaseModel

uvicorn -b 0.0.0.0:5020 main:app --reload

# main is the main.py file
# app = FastAPI() instance
# -b binds to particular host and port
# --reload automatically refreshes as soon as we make changes to main.py and save

• FastAPI reads the file line-by-line so if there is any error at the start, we don't reach to the lower part of the file
