python采用mvc设计web应用athletemodel.py不显示数据

今天，继续研究python，在看到采用mvc设计web应用时，抄写athletemodel.py，点击保存。点击运行(按F5)

这时重新打开了一个IDLE，我点击了关闭，还在原来的IDLE中继续操作，先写了dir(),显示结果正常，但是往下的操作就不正常了，

>>> dir()

['AthleteList', '__annotations__', '__builtins__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', 'athl', 'athletemodel', 'athlist', 'data', 'data11', 'get_coach_data', 'get_from_store', 'pickle', 'put_to_store', 'the_files']

>>> from athletemodel import put_to_store

>>> the_files = ['sarah.txt', 'julie.txt', 'mikey.txt', 'james.txt']

>>> data11 = put_to_store(the_files)

>>> data11

下面什么也不显示~~~为什么？

查google，找度娘，代码一字一字对，最后在点F5运行之后，打开的新的IDLE中又写了一遍如上的代码，最后结果出现了！难道是因为刷新编译的问题吗？
