I'm programming a data analysis programme for a psychology experiment which takes pickled data from the experiment and produces averages. For some reason python is insisting there is an indentation error on line 18. I have untabified and retabified and nothing seems to work. Here is the full code:

You didn't include the error message, so how are we supposed to know
which line is #18 ?  if I take your message literally, it's a blank line.

Even better, you could have reduced the code down to a minimum which
still shows the error.

As your code stands now, I get an error on line 10:

 File "daniel.py", line 10
    partifipant_info=data'Participant Info']
                                          ^
SyntaxError: invalid syntax

It appears you're missing a left bracket.

That line also has a strange spelling for participant, so you'd get an
error later when you tried to use participant_info.   Did you by any
chance retype your program into the message?  If you don't use
copy/paste, it's useless for us to study your code.

Finally, in case it matters, just what version of python did you use,
and on what OS?
