The datetime class in Python is part of the datetime module and is used to represent both date and time together, with optional time zone support. It allows you to create, manipulate, and format date-time objects with precision, making it essential for scheduling, logging, and time-based calculations.
In Python, the % symbol is the modulus operator. It returns the remainder when one number is divided by another.
In Python, pass is a placeholder statement that literally means “do nothing.”
from datetime import datetime
wait_until = (datetime.now().second + 2) % 60
datetime.now().second→ gets the current second (0–59).+ 2→ adds 2 seconds to the current time.% 60→ ensures the value wraps around correctly (e.g., if current second is 59,59 + 2 = 61, and61 % 60 = 1).
So wait_until is always two seconds ahead of the current second.
while datetime.now().second != wait_until: print('Still waiting!')
This loop keeps checking the current second.
As long as it’s not equal to
wait_until, it prints"Still waiting!".
wait_until, the loop ends.f in print(f"...") is shorthand for an f‑string, also called a formatted string literal. It lets you embed variables or expressions directly inside a string using curly braces {}.
wait_until is set to 2 seconds ahead of the current second (wrapped with % 60).while True: loop runs indefinitely.
while → starts a loop that repeats as long as its condition is True.True → is a Boolean literal that always evaluates to true.while True: means “keep looping forever” because the condition never becomes false on its own.if datetime.now().second == wait_until.break exits the loop.break exits the inner loop.break only stops the inner loop, not the outer while True: loop.
wait_until is set to 2 seconds ahead of the current second (wrapped with % 60).while loop runs until the current second equals wait_until.
continue immediately jumps back to the start of the loop, skipping everything after it.print('Still waiting!') line is never executed.wait_until is set to 2 seconds ahead of the current second, wrapped with % 60.while True:) wait_until, the loop executes continue.continue skips the rest of the loop body and goes back to the top, so nothing else happens.wait_until (i.e., equal or greater), the loop executes break.18.wait_until = (18 + 2) % 60 = 20.18, 19), the loop keeps spinning.
