*** ✅ *Python Logic Building Interview Question* 🧠🐍 You have a list of numbers:

nums = [3, 5, 7, 9, 12, 17, 20, 21]

*Question:* Find and print all numbers in the list that are prime. *Expected Output:*

[3, 5, 7, 17]

*Python Code:*

def is_prime(n):
    if n < 2:
        return False
    for i in range(2, int(n**0.5) + 1):
        if n % i == 0:
            return False
    return True

prime_nums = [n for n in nums if is_prime(n)]
print(prime_nums)

*Explanation:* – Checks each number with is_prime() logic – Uses list comprehension for concise filtering – Prints list of all prime numbers 💬 *Tap ❤️ for more logic-building questions!*

✅ *Python Scenario-Based Interview Question* 🧠🐍 You have a list:

numbers = [1, 2, 3, 2, 4, 1, 5, 2]

*Question:* Find the number that appears most frequently in the list. *Expected Output:*

2

*Python Code:*

from collections import Counter

most_common_num = Counter(numbers).most_common(1)[0][0]
print(most_common_num)

*Explanation:* – Counter() counts occurrences of each element – most_common(1) returns the most frequent item – Access [0][0] to get just the number 💬 *Tap ❤️ for more bite-sized Python tips!* *** Would you like the next one to be slightly more advanced (e.g., involving strings or list comprehensions)?
