The 409 (Conflict) status code indicates that the request
could not be completed due to a conflict with the current
state of the target resource. This code is used in situations
where the user might be able to resolve the conflict and resubmit the request.
The server SHOULD generate a payload that includes enough
information for a user to recognize the source of the conflict.

# The HTTP 409 error code signifies a conflict when the requested resource conflicts
# with the current state of the server. Here's an example of how to handle it in Python:
import requests
url = "https://example.com/api/resource"
try:
response = requests.get(url)
if response.status_code == 200:
# Successful response
data = response.json()
# Process the data here
elif response.status_code == 409:
# Conflict, resource conflict with the server's current state
print("409 Conflict: There is a conflict with the requested resource.")
# Handle the conflict appropriately
else:
print(f"Request failed with status code {response.status_code}")
# Handle other response codes as needed
except requests.exceptions.RequestException as e:
print("Error occurred:", e)
# Handle the exception here
