input: Write a function to rewrite the given Python code using list comprehensions. The original code initializes an empty list and iterates through numbers from 1 to 20, appending even numbers to the list. The rewritten code should achieve the same result using a list comprehension.
  assert rewrite_with_comprehension() == [i for i in range(1, 21) if i % 2 == 0]
output: def rewrite_with_comprehension():
      return [i for i in range(1, 21) if i % 2 == 0]
