import re

lists = {}
cmd = input("> ")

if cmd.startswith("Create a list called"):
    name = cmd.split("called")[-1].strip('" .')
    lists[name] = []

elif cmd.startswith("Add") and "to" in cmd:
    parts = cmd.split("to")
    val = parts[0].replace("Add","").strip('" ')
    name = parts[1].strip()
    if name in lists: lists[name].append(val)

elif cmd.startswith("Print all items in"):
    name = cmd.replace("Print all items in","").strip()
    print(lists.get(name, []))

elif re.match(r"Repeat \d+ times:", cmd):
    count = int(re.search(r"\d+", cmd).group())
    sub = cmd.split(":",1)[1]
    for _ in range(count):
        exec(sub)   # 仅原型演示
