✅ *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

✅ *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
