I have been having issues like the below all day:

C:\JMK\CurrentWork\CPH-3516>python airport_code_downloader.py
Traceback (most recent call last):
  File "airport_code_downloader.py", line 4, in <module>
    import inspect
  File "C:\Python33\lib\inspect.py", line 53, in <module>
    from dis import COMPILER_FLAG_NAMES as _flag_names
  File "C:\Python33\lib\dis.py", line 13, in <module>
    _have_code = (types.MethodType, types.FunctionType, types.CodeType, type)
AttributeError: 'module' object has no attribute 'MethodType'

C:\JMK\CurrentWork\CPH-3516>

It seems to be a problem with the types module. All the types seem non-existing.
