Python Script Optimization for Website Login

I have a Python script that logs into a specific website using a username and password. However, the website occasionally blocks the login attempts after a certain amount of traffic from the script. I need a Python automation expert who has experience in similar work to optimize my script. The main objective once logged in is to navigate to specific sections of the website.

Ideal Skills and Experience:
- Proficiency in Python programming
- Previous experience in web automation
- Understanding of login mechanisms and traffic management
- Ability to optimize scripts for efficiency
- Familiarity with website navigation post-login
