Use the modulo%operator to check if a number is divisible by another number. The modulo%operator returns the remainder from the division of the first number by the second. If the remainder is0, the number is divisible by the other number. main.py if9%3==0:# 👇️ this runsprint('...

print_first_10_primes() Explanation: Prime Check Function (is_prime): This function checks if a number is prime by testing its divisibility from 2 up to the square root of the number. Main Function (print_first_10_primes): This function uses a while loop to find and print the first 10...

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...
