python coding interview questions and answers for experienced

in this tutorial, we will cover some common python coding interview questions that are frequently asked in technical interviews for experienced candidates. each question will be accompanied by a detailed explanation and python code examples to help you understand the solutions better.
problem statement: write a python function to reverse a given string.
solution:
explanation: the solution involves using python's slicing feature. [::-1] slices the string from the end to the beginning, effectively reversing it.
problem statement: write a python function to check if a given string is a palindrome.
solution:
explanation: we compare the original string with its reverse. if they are the same, the string is a palindrome.
problem statement: write a python function to find the factorial of a given number.
solution:
explanation: this solution uses recursion to calculate the factorial of a number. if n is zero, the factorial is 1. otherwise, it recursively calls the factorial function with n-1 until n becomes zero.
problem statement: write a python function to check if a given number is prime.
solution:
explanation: this solution uses a common algorithm to check for prime numbers. it iterates through numbers up to the square root of n, checking divisibility.
in this tutorial, we covered some common python coding interview questions and provided solutions with code examples. practice these questions to improve your problem-solving skills and increase your chances of success in python coding interviews. remember to understand the underlying concepts behind each solution and optimize them further if possible. happy coding!
