Answer 2

def remove_last_word(s: str) -> str:
    # Trim trailing whitespace
    s = s.rstrip()

    # Find last space
    pos = s.rfind(" ")

    # If no space found, return original
    if pos == -1:
        return s

    return s[:pos]


def main():
    s = "c c++ c# java python"
    print("1.", remove_last_word(s))

    s = ""
    print("2.", remove_last_word(s))

    s = "c"
    print("3.", remove_last_word(s))

    s = "c# java python "
    print("4.", remove_last_word(s))

    s = "  "
    print("5.", remove_last_word(s))
