Question

I'm getting an indention error in the following code:

IndentationError: unexpected indent

...which doesn't make any sense to me because I've checked to make sure everything is properly indented! I've stared at this for hours and am resigned to the fact that I need have help.

To be completely honest, I'm not entirely sure why I had to surround "droplet" with parens at line 35, and my guess is that's what's causing the problem, but I can't tell you with certainty that the issue is related to that.

For the record, I'm using Python 2.7.9.

Thanks in advance for any help!

Answer 1

Your function indent is three spaces, while the indentation of your try...except block is two spaces. Fix this and it should work.

PEP 8 recommends four spaces for indenting code, though.
