[python2] TypeError: string indices must be integers about pympress HOT 4 CLOSED

This error is seen when I use python2. With python3 it is OK

from pympress.

I just added some additional logging to the method which produces this error: In line 546, I added print(type(w_desc)) and print(w_desc) before line 577.

Output for python -m pympress running the latest master with Python 2.7:

<type 'dict'>
<type 'dict'>
<type 'unicode'>
current
current

Output for python3 -m pympress running the latest master with Python 3.5 (I exited the application when the file chooser was shown):

<class 'dict'>
<class 'dict'>
<class 'str'>
current
<class 'str'>
annotations
<class 'str'>
next

Seems like the if condition in line 547 needs to be extended using something like

if type(w_desc) is str or type(w_desc) is unicode:
    w = self.placeable_widgets[w_desc]

The problem is that Python 3 does not have the unicode type, so this part of the code probably needs to be rewritten to be able to support both Python 2 and Python 3 (the snippet above does not work for Python 3):

is_string = False
try:
    is_string = type(w_desc) is unicode
except NameError:
    is_string = type(w_desc) is str

if is_string:
    w = self.placeable_widgets[w_desc]

Done! Thanks for reporting. Should work OK even on python2 now, as far as I can tell.

You are fast as lightning :-)
