Trying to update to Inactive email address through SKY API

Hi Everyone,
I am planning to work on Updating inactive email address using SKY API using Python by calling the Patch Email Address (Edit)
https://api.sky.blackbaud.com/constituent/v1/emailaddresses/{email_address_id}
When I look at the URL of API call we are not passing any Authorization Token and API Subscription Key in the URL.
When I was trying the test option in the SKY API

It has four sections
1) Authorization section

The authorization token will expires after specific time how do I generate new Authorization Bear Token? what are the step I have to follow if I have to implement this in Python
2) Parameter section
This is the place where I pass my unique email_address_id

3) Headers Section
This is the place where I pass my API Subscription key and Bear Authorization Token

4) Body Section

Do I have to pass any keys other than these? How to autogenerate the authorization bear token if it expires?
Thank you!
