Develop a program that can fetch a given website's HTML code.
Here is a simple Python script that can fetch the HTML source code of a given website using the requests module:

```python
import requests

url = input("Enter the URL of the website: ")
response = requests.get(url)
if response.status_code == 200:
    html_content = response.text
    print("The HTML source code of the website is: \n{}".format(html_content))
else:
    print("An error occurred while fetching the HTML code, please check the provided URL.")
``` 
In this code, the user is prompted to enter the URL of the website. Then, we use the `requests.get()` function to send a GET request to the given URL. If the response is successful (HTTP status code 200), the HTML content is fetched by accessing the `text` attribute of the `response` object. Finally, the HTML source code is printed to the console. If the response is not successful, an error message is printed.
Complete the following task based on the instruction and optional input provided.### Instruction:
