There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “To switch back to the original main branch, we run git checkout main.”

A block of code is set as follows:

from fastapi import FastAPI
from routes.user import user_router
import uvicorn

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

from pydantic import BaseModel
from typing import List
class Event(BaseModel):
    id: int
    title: str
    image: str
    description: str
    tags: List[str]
    location: str

Any command-line input or output is written as follows:

$ git add hello.txt
$ git commit -m "Initial commit"

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “As shown in the previous model diagram, each user will have an Events field, which is a list of the events they have ownership of.”
