Medium:
6. Filter prime numbers between 1 and 50:
Output: []
7. FizzBuzz (replace multiples of 3 with "Fizz" and multiples of 5 with "Buzz"): 6. Filter prime numbers between 1 and 50:
Output: []
Output: [1, 2, 'Fizz', 4, 'Buzz', 'Fizz', 7, 8, 'Fizz', 'Buzz', 11, 'Fizz', 13, 14,
'FizzBuzz', 16, 17, 'Fizz', 19, 'Buzz']
8. Generate a list of all the words in a sentence that have more than 3 letters using a list comprehension. Output: ['List', 'comprehensions', 'powerful', 'concise']
9. Create a list of tuples using list comprehension where each tuple contains a number and its cube, for numbers from 1 to 10. Output: [(1, 1), (2, 8), (3, 27), (4, 64), (5, 125), (6, 216), (7, 343), (8, 512), (9, 729), (10, 1000)]
10. Write a list comprehension that takes a list of integers and produces another list where each element is doubled if it's even, and halved if it's odd. Output: []
Hard:
11. Generate all Pythagorean triples up to 20: Output: [(3, 4, 5), (5, 12, 13), (6, 8, 10), (8, 15, 17), (9, 12, 15), (12, 16, 20)]
