{‘name = “John”\nage = 30\nprint(f”My name is {name} and I am {age} years old.”)’, ‘Use f-strings for string formatting.’}
Write a program that counts the occurrences of each word in a given text.
{‘text = “hello world”\nword_counts = {}\nfor word in text.split():\n word_counts[word] = word_counts.get(word, 0) + 1’, ‘Use dictionary to count word occurrences.’}
Use a set to remove duplicates from a list.
{‘numbers = [1, 2, 2, 3, 4, 4]\nunique_numbers = list(set(numbers))’, ‘Use set to remove duplicates from a list.’}
Write a function that takes a list and returns a list of squares of the numbers.
{‘def square_list(lst):\n return [x**2 for x in lst]’, ‘Use list comprehension to generate a list.’}
Create a tuple and print its elements using a for loop.
{‘my_tuple = (1, 2, 3)\nfor item in my_tuple:\n print(item)’, ‘Iterate through a tuple using a for loop.’}

{‘def factorial(n):\n if n == 0:\n return 1\n else:\n return n * factorial(n-1)’, ‘Use recursion to calculate factorial.’}
Create a list comprehension to generate a list of squares of numbers from 1 to 10.
{‘squares = [x**2 for x in range(1, 11)]’, ‘Use list comprehension for concise loops.’}
Write a program that checks if a string is a palindrome.
{‘def is_palindrome(s):\n return s == s[::-1]’, ‘Check if a string reads the same forwards and backwards.’}
