## Make Request

Sometimes we might want to make a request to a website programmatically. Instead of having to visit the page in the browser. In Python we can to it the following way.

```

Here is the documentation

## Read and write to files

```

### Send requests to your proxy \(like Burp\)

```

import os

os.environ['HTTPS_PROXY'] = '<proxyurl>:<port>' 

# http://127.0.0.1:8080 if it is burp

```

## Basic banner-grabber

Here is an example of the most basic usage of the socket module. It connects to a port and prints out the response.

# Here we close the socket.

s.close

```

If you need to check all 65535 ports this might take some time. If a packet is sent and recieved that makes it 65535 seconds, it translates into about 18 hours. So to solve that we can run the a function in new threads.

results = pool.map(function, array)

```
