Can you list the main HTTP methods and their functions?

Main HTTP methods and their functions:

• GET — requests data from the server. Used to retrieve information without changing the state.
• POST — sends data to the server to create a resource or perform an action.
• PUT — updates an existing resource or creates it if it does not exist.
• DELETE — deletes the specified resource on the server.
• PATCH — partially updates a resource, changing only specified fields.
• HEAD — requests only the response headers, without the body, to check metadata.

Example of using GET and POST in Python with requests:

import requests

response = requests.get('https://api.example.com/items')
print(response.json())

response = requests.post('https://api.example.com/items', json={'name': 'NewItem'})
print(response.status_code)
