✅ *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)
is_prime() logic
– Uses list comprehension for concise filtering
– Prints list of all prime numbers

✅ *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)
Counter() counts occurrences of each element
– most_common(1) returns the most frequent item
– Access [0][0] to get just the number
