# First Steps

The simplest FastAPI file could look like this:

```Python
{!../../../docs_src/first_steps/tutorial001.py!}
```

Copy that to a file `main.py`.

Run the live server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

### In a Remote Server

When you set up a remote server (a cloud server, a virtual machine, etc.) the simplest thing you can do is to use `fastapi run`, Uvicorn (or similar) manually, the same way you do when developing locally.

And it will work and will be useful **during development**.

If you can use the **latest versions of Python**, use the examples for the latest version, those will have the **best and simplest syntax**, for example, "**Python 3.10+**".

#### List

For example, let's define a variable to be a `list` of `str`.

=== "Python 3.9+"

    Declare the variable, with the same colon (`:`) syntax.

  // A consequence of these requirements is that the delegate futures cannot be stored in
  // final fields.
  //
  // For simplicity the rest of this description will discuss Futures.catching since it is the
  // simplest instance, though very similar descriptions apply to many other classes in this file.
  //
  // In the constructor of AbstractCatchingFuture, the delegate future is assigned to a field

### Step 3: Test on NSQ

The simplest test is to download `nsq_tail` from [nsq github](https://github.com/nsqio/nsq/releases)

```
./nsq_tail -nsqd-tcp-address 127.0.0.1:4150 -topic minio
```
