Constructing a List from Another List

One typical kind of list processing is to construct a list from information in another list. This is typically done by iterating over the input list using a for loop and building up the result in another list.

Write a function definition of all_gt that takes a list of numbers, say nums, and a number, say n and returns the list of numbers from nums that are greater than n. The order of elements should be preserved.

For example:
all_gt([1,2,3,4], 2) => [3,4]
all_gt([1,2,3,4], 4) => []

def all_gt(nums, n):
"""Return the list of all numbers from nums that are bigger than n.

Parameters:
nums (list<number>): a list of numbers
n (number): threshold value

Return:
list<numbers>: numbers which are > n
  
"""

Answer 1

def all_gt(nums, n):
    """Return the list of all numbers from nums that are bigger than n.

    Parameters:
    nums (list<number>): a list of numbers
    n (number): threshold value

    Return:
    list<numbers>: numbers which are > n

    """
    result = []
    for num in nums:
        if num > n:
            result.append(num)
    return result


print(all_gt([1, 2, 3, 4], 2))
print(all_gt([1, 2, 3, 4], 4))
