What Python coding interview questions are important for freshers?

For freshers preparing for Python coding interviews, it's important to focus on fundamental concepts, basic data structures, and common algorithms. Here are some essential Python coding interview questions that freshers should be familiar with:

1. Reverse a String

Question: Write a function to reverse a string.

Example Solution:

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

Resources: This is a common introductory question, often discussed in coding practice platforms like GeeksforGeeks and LeetCode.

2. Check for Palindrome

Question: Write a function that checks if a string is a palindrome.

Example Solution:

def is_palindrome(s):
    return s == s[::-1]

Resources: Palindrome checks are frequently featured in beginner coding challenges, such as those on HackerRank and Codecademy.

3. Find the Largest Element in a List

Question: Write a function that returns the largest number from a list.

Example Solution:

def find_largest(numbers):
    return max(numbers)

Resources: This problem helps assess basic list manipulation skills, often found in resources like W3Schools and GeeksforGeeks.

4. Fibonacci Sequence

Question: Write a function to generate the Fibonacci sequence up to n terms.

Example Solution:

def fibonacci(n):
    sequence = [0, 1]
    while len(sequence) < n:
        sequence.append(sequence[-1] + sequence[-2])
    return sequence[:n]

Resources: Fibonacci-related problems are common in interviews and coding exercises, with examples on Project Euler and LeetCode.

5. Count Vowels in a String

Question: Write a function that counts the number of vowels in a given string.

Example Solution:

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

Resources: This question evaluates string manipulation skills and is frequently included in beginner-level exercises on platforms like GeeksforGeeks and HackerRank.

Conclusion

These questions test fundamental Python skills and understanding of programming concepts, making them essential for freshers preparing for coding interviews. Practicing these types of problems can significantly enhance readiness for technical interviews.
