Python asyncio.sleep SyntaxError

Question

What am I doing wrong? When I run this,

import asyncio
def oneSecond():
    await asyncio.sleep(1)

I get this:

File "<string>", line 3
await asyncio.sleep(1)
            ^
SyntaxError: invalid syntax

Using Python 3.3

You are using the await keyword with Python 3.3 but it has not been added to Python before version 3.5. You should upgrade your Python version.

Also you will have to define your function as async:

async def oneSecond():
    await asyncio.sleep(1)

Identical problem on 3.5.1

I edited the the answer with an additional problem being solved.

Now when I do await oneSecond() it's a syntax error.

You have to start it inside asyncio event loop.
