To obtain a token from the Cisco DNA Center API using HTTP Basic Authentication, the requests library in Python is used. The missing line of code in the snippet should set up HTTP Basic Authentication as follows:
auth=HTTPBasicAuth(user,password)
* HTTPBasicAuth: This is a class from the requests.auth module that handles HTTP Basic Authentication.
* user, password: These are the credentials required for authentication.
The correct line of code that completes the script to obtain a token from Cisco DNA Center API is:
python
Copy code
auth=HTTPBasicAuth(user,password)
