How I would do it ....

def show_exits(exits):
    ret = []
    for x in range(0, len(direction_names)):
        if exits[x]:
            ret.append(direction_names[x])

     if len(ret) > 1:
         ret[-1] = f"and {ret[-1]}"

     print(f"Ye may travel: {", ".join(ret)}")

Or:

def show_exits(exits):
    ret = [
        direction_names[x]
         for x in range(0, len(direction_names))
         if exits[x]
    ]

     if len(ret) > 1:
         ret[-1] = f"and {ret[-1]}"

     print(f"Ye may travel: {", ".join(ret)}")
