To check if a number is prime in Python, you can use an optimized iterative method. First, check if the number is less than or equal to 1; if so, it’s not prime. Then, iterate from 2 to the square root of the number, checking for divisibility. If the number is divisible by any...

In other words, you may need to check if a given value is or is not a member of a collection of values. Python calls this kind of check a membership test. Note: For a deep dive into how Python’s membership tests work, check out Python’s “in” and “not in” Operators: Check...
