# Problem 1
def first_character(input_list):
    '''
    Write a one-line list comprehension that returns a list containing
    the first letter of each string in the input list.
    Returns an empty list if the input list has no elements

    Arguments:
        input_list: a list of strings. You may assume all strings
        are at least one character long

    Returns: a list of strings
