How to organize time measurements of the test?

Question

Python

Good afternoon! I am new to testing, I encountered such situations:
1) it is necessary to measure the site opening time, let it be any site, I write the test in the class, I run it - the test time shows completely from the moment the browser was opened, but it is necessary to measure from the moment the address is entered and pressing Enter until the site is fully loaded.
2) How to correctly divide the time of tests? for example, after the test in paragraph 1, I want to further click on the link on the page and measure the execution time of this particular action, are there any functions / methods so that I describe everything in one class and the measurement time is given separately (test1 - 3s, test2 - 2s)?
in fact, all questions come down to work on measuring tests, please direct me to the right path

Answer 1

Take a snapshot of the date before .get() and then, after setting an anchor that will tell you when the page has fully loaded (Wait.Until), take a second snapshot and then a delta.
