我是python的初学者.我面临以下问题.
每当我启动pycharm社区版(版本5.0.3)时,Python控制台无法启动并显示以下错误:
usr/bin/python2.7 /usr/lib/pycharm-community/helpers/pydev/pydevconsole.py 53192 49994

File "/usr/lib/python2.7/dist-packages/IPython/core/interactiveshell.py", line 483, …Python 的内置异常文档定义LookupError为：
当映射或序列上使用的键或索引无效时引发的异常的基类：IndexError、KeyError。这可以通过 codecs.lookup() 直接引发。
这个基类应该只在捕获使用索引和键访问字典的尝试部分时使用，当一个人想要速记捕获两者时，还是有另一种情况下你会使用它？
我正在编写一个Elm测试套件,并希望使用存储在外部文件中的已知良好输入/输出对列表来检查函数的输出.我可以选择外部文件的格式,所以我可以使用JSON,但我需要将它分开,因为它是从其他语言访问的.(我基本上确保该函数的Elm版本与其他版本匹配).
我不想将值硬编码到Elm测试模块中.有没有办法用Elm和elm-test做到这一点？
