TypeError: session() got an unexpected keyword argument 'url'

This error occurs when you are trying to pass an invalid keyword argument to a function. In this case, the error message is indicating that the `session()` function is receiving an unexpected keyword argument `url`.

The `session()` function is a part of the `requests` library in Python, and it is used to create a persistent HTTP connection between a client and a server.

This error can occur if you are trying to pass an invalid keyword argument to the `session()` function. To fix this error, make sure that you are passing only valid keyword arguments to the function.

Here is an example of how to create a session with the `requests` library:

import requests

# Create a session
session = requests.Session()

# Use the session to make requests
response = session.get('http://example.com')

# Close the session when you are done
session.close()

Notice that we are passing a valid keyword argument `get` to the `session()` function, which specifies the type of HTTP request to make. If you are still experiencing issues, double-check the documentation for the specific function you are using to ensure that you are passing valid arguments.
