照书本上抄的代码,为啥不运行?

responses={}

polling_active=True

while polling_active:
    name=input("\nWhat is your name?")
    response=input("which mountain would you like to climp someday?")

    responses[name]=response

    repeat=input("Would you like to let another person respond?(yes/no")
    if repeat=='no':
        polling_active=False

print("\n---Poll Result---")
for name,response in response.items():
    print(name+" would like to climb"+response+".")


错误信息:
