I need a simple script written in Python to interact with LinkedIn. Requirements: *It should receive user credentials for authentication by keyboard input *It should not use LinkedIn API, but yes Selenium or similar through browser requests *It should receive a keyword for the searching and a number to define how many entries (profiles) from the result should be selected *It should read a custom message from a text file, add the profiles resulted from the search and send the custom message to them, being able to replace a specific variable for their profile name *Code should be written according to best practices, allowing other developers to understand and modify it in a easy way
