Our team of expert programmers is dedicated to helping students like you navigate through the intricacies of Python programming and excel in your coursework. In this blog post, we'll explore some master-level Python programming questions and provide expert solutions to help you sharpen your skills and ace your assignments.

Question 1:

You've been tasked with implementing a function in Python that checks whether a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequences of characters that reads the same forward and backward (ignoring spaces, punctuation, and capitalization). Write a Python function named is_palindrome that takes a string as input and returns True if the string is a palindrome and False otherwise.

Solution:

def is_palindrome(s):
    s = ''.join(ch.lower() for ch in s if ch.isalnum())
    return s == s[::-1]

# Test cases
print(is_palindrome("A man, a plan, a canal, Panama!"))  # True
print(is_palindrome("python"))  # False

Explanation:

In the is_palindrome function, we first preprocess the input string s by removing non-alphanumeric characters and converting all characters to lowercase. Then, we compare the processed string with its reverse using slicing ([::-1]). If the processed string is equal to its reverse, we return True, indicating that the string is a palindrome; otherwise, we return False.

This solution demonstrates the power of Python's built-in string manipulation methods and list comprehensions in solving such problems efficiently.

Question 2:

You're working on a Python program that requires parsing a CSV (Comma-Separated Values) file and extracting specific information from it. Write a Python function named parse_csv that takes the filename of a CSV file as input and returns a list of dictionaries, where each dictionary represents a row in the CSV file, with keys as column headers and values as corresponding values in the row.

Solution:

import csv

def parse_csv(filename):
    data = []
    with open(filename, 'r') as file:
        reader = csv.DictReader(file)
        for row in reader:
            data.append(dict(row))
    return data

# Test case
print(parse_csv("data.csv"))

Explanation:

In the parse_csv function, we open the CSV file using the open function and create a csv.DictReader object to read the file. The csv.DictReader automatically interprets the first row of the CSV file as column headers, allowing us to access data by column names. We iterate over each row in the CSV file and convert it into a dictionary using dict(row), where row is a DictReader object representing a row in the CSV file. Finally, we append each dictionary representing a row to the data list and return it.

This solution demonstrates how Python's built-in csv module simplifies the process of parsing CSV files and extracting data, making it an ideal choice for data manipulation tasks.
