Make sure you don't mix tabs and spaces and make consistent indentation. 
In your above example, the problem is that "if" is indented one more 
space than "else". If I paste this into ipython (3.6.1), I get:

File "<ipython-input-3-21b11970a3df>", line 4
     else:
          ^
IndentationError: unindent does not match any outer indentation level

which is a pretty clear error. I'm not sure which version of Python you 
are using which only displays "wrong syntax" instead of a descriptive 
error message. I suggest in any case to use IPython for interactive use.

I can't see an error here, it only fails for me because the functions 
"get_next_item" and "process_item" are not defined. Maybe the 
tabs/spaces were mixed in your original input?
