Code blocks

Code blocks can be easily represented with the code-block directive. Together with Pygments, Sphinx will automatically highlight the syntax. You can specify the appropriate language for a code block with

.. code-block:: LANGUAGE

You can use this for example like this:

.. code-block:: python

   import this

Optionen

:linenos:

For code-block, the linenos option can also be used to specify that the code block should be displayed with line numbers:

.. code-block:: python
   :linenos:

   import this

import this

:lineno-start:

Die erste Zeilennummer kann mit der lineno-start-Option ausgewählt werden; linenos wird dann automatisch aktiviert: The first line number can be selected with the lineno-start option; linenos will then be activated automatically:

.. code-block:: python
   :lineno-start: 10

   import antigravity

import antigravity

:emphasize-lines:

emphasize-lines allows you to emphasise individual lines.

.. literalinclude:: FILENAME

allows you to include external files.

Options

:emphasize-lines:

:linenos:

Here is an example from our Jupyter Tutorial:

.. literalinclude:: main.py
   :emphasize-lines: 4, 9-12, 20-22
   :linenos:

from typing import Optional

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Task(BaseModel):
    name: str
    price: float
    is_offer: Optional[bool] = None


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/cusy.tasks/{task_id}")
def read_task(task_id: int, q: Optional[str] = None):
    return {"task_id": task_id, "q": q}


@app.put("/cusy.tasks/{task_id}")
def update_task(task_id: int, task: Task):
    return {"task_name": task.name, "task_id": task_id}

:diff:

If you want to show the diff of your code, you can specify the old file with the diff option, for example:

.. literalinclude:: main.py
   :diff: main.py.orig

Obsolete code

.. deprecated:: version

Describes when the function became obsolete. An explanation can also be given to inform what should be used instead. For example

.. deprecated:: 4.1
   instead use :func:`new_function`.

Deprecated since version 4.1: instead use new_function().

:py:module:deprecated:

Marks a Python module as obsolete; it is then marked as such in various places.
