First you need to install an aiohttp package. To install aiohttp run the command:
```bash
pip install aiohttp[speedups]
```<!--more-->
The `[speedups]` suffix is needed to install aiohttp accelerating packages - aiodns and cchardet. Then create a main.py file with this code:
```python
import aiohttp
import asyncio
import socket


async def fetch_urls(urls):
	resolver = aiohttp.AsyncResolver()
	connector = aiohttp.TCPConnector(resolver=resolver, family=socket.AF_INET, use_dns_cache=False)
	session = aiohttp.ClientSession(connector=connector)

	async def fetch_url(url, session):
		async with session.get(url) as resp:
			print(resp.status)
			print(await resp.text())

	tasks = [fetch_url(url, session) for url in urls]
	await asyncio.gather(*tasks)
	await session.close()


loop = asyncio.get_event_loop()

urls = ['http://httpbin.org/get?key=value1', 'http://httpbin.org/get?key=value2', 'http://httpbin.org/get?key=value3']

loop.run_until_complete(fetch_urls(urls))							

```
Now you can run main.py file with the command:
```bash
python3 main.py
```
You will see this output:
```plaintext
200
{
	"args": {
	"key": "value2"
	}, 
	"headers": {
	"Accept": "*/*", 
	"Accept-Encoding": "gzip, deflate", 
...				

```
All three queries will be executed in parallel. You can add any urls to the `urls` list, for example:
```python
urls = ['https://yandex.com', 'https://google.com', 'https://yahoo.com']
```

In order to make HEAD, POST, PUT, DELETE requests, just replace `session.get(url)` in your code with the appropriate method:
```python
session.post('http://httpbin.org/post', data=b'data')
session.put('http://httpbin.org/put', data=b'data')
session.delete('http://httpbin.org/delete')
session.head('http://httpbin.org/get')
session.options('http://httpbin.org/get')
session.patch('http://httpbin.org/patch', data=b'data')

```
