Python Coding Interview Questions with Answers: A Practical Guide for Indian Job Seekers

Python interviews are rarely about writing perfect code. They’re about how you think, how clearly you explain, and whether you truly understand the basics behind the syntax. That’s where many candidates slip.

Whether you’re a fresher, a college student, or someone switching careers into tech, Python interviews in India often follow familiar patterns. Same concepts. Same traps. Different pressure.

This guide breaks down Python coding interview questions with answers in a simple, human way. No heavy theory. No confusing jargon. Just what interviewers actually expect you to know.

Why Python Coding Interview Questions Matter

Interviewers don’t ask Python questions to test memory. They ask them to check logic, clarity, and problem-solving style.

If you understand why a piece of code works, you can handle:

• Whiteboard rounds
• Online coding tests
• Follow-up “why did you do it this way?” questions

That confidence shows instantly.

Basic Python Coding Interview Questions

1. Reverse a String

Q: Write code to reverse a given string.

Python Code:

def reverse_string(s):
    return s[::-1]

print(reverse_string("hello"))  # Output: "olleh"

2. Check Palindrome

Q: Check if a string is a palindrome (ignoring spaces & case).

Python Code:

def is_palindrome(s):
    s = s.replace(" ", "").lower()
    return s == s[::-1]

print(is_palindrome("Race car"))  # Output: True

3. Find Duplicate Elements in List

Q: Print all duplicates from a list.

Python Code:

from collections import Counter

def find_duplicates(lst):
    count = Counter(lst)
    return [item for item, freq in count.items() if freq > 1]

print(find_duplicates([1, 2, 3, 2, 4, 1]))  # Output: [1, 2]

4. Count Vowels in a String

Q: Count number of vowels in a string.

Python Code:

def count_vowels(s):
    return sum(1 for char in s.lower() if char in "aeiou")

print(count_vowels("Python is fun"))  # Output: 4

5. Find Factorial Using Recursion

Q: Write a recursive function to find factorial.

Python Code:

def factorial(n):
    if n == 0 or n == 1:
        return 1
    return n * factorial(n - 1)

print(factorial(5))  
# Output: 120

6. Find the Largest Element in a List

Q: Return the largest number in a list.

Python Code:

def find_max(lst):
    return max(lst)

print(find_max([3, 7, 2, 9, 5]))  # Output: 9

7. Check for Anagrams

Q: Check if two strings are anagrams.

Python Code:

def are_anagrams(s1, s2):
    return sorted(s1.lower()) == sorted(s2.lower())

print(are_anagrams("listen", "silent"))  # Output: True

8. Remove Punctuation from String

Q: Clean a string by removing all punctuation.

Python Code:

import string

def remove_punctuation(s):
    return ''.join(c for c in s if c not in string.punctuation)

print(remove_punctuation("Hello, World!"))  # Output: Hello World

9. Fibonacci Using Recursion

Q: Generate nth Fibonacci number.

Python Code:

def fibonacci(n):
    if n <= 1:
        return n
    return fibonacci(n-1) + fibonacci(n-2)

print(fibonacci(6))  # Output: 8

10. Flatten a Nested List

Q: Flatten a list of lists into a single list.

Python Code:

def flatten(lst):
    return [item for sublist in lst for item in sublist]

print(flatten([[1, 2], [3, 4], [5]]))  # Output: [1, 2, 3, 4, 5]
