## Install FastAPI { #install-fastapi }

The first step is to install FastAPI.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then **install FastAPI**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

					fmt.Println("Internal error: Found filled data at", startOffset+i)
				}
				splitFilled[shardsIdx][startOffset+i] = 1
			}
			reconstructed += len(shards[shardsIdx])
		} else {
			for i := range shards[shardsIdx] {
				if splitFilled[shardsIdx][startOffset+i] == 0 {
					fmt.Println("Internal error: Expected filled data at", startOffset+i)
				}

例如，您可以创建一个名为 `config.py` 的文件，其中包含以下内容：

{* ../../docs_src/settings/app01/config.py *}

然后在一个名为 `main.py` 的文件中使用它：

{* ../../docs_src/settings/app01/main.py hl[3,11:13] *}

/// tip

您还需要一个名为 `__init__.py` 的文件，就像您在[Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}中看到的那样。
