You get the following errors with python 2 if you follow the instructions
on the lesson webpage:
$ python wordcount.py books/isles.txt isles.dat
File "wordcount.py", line 79
return sorted(counts.iteritems(), key=lambda (key,value): value, \
^
SyntaxError: invalid syntax
and
$ python plotcount.py isles.dat show
Traceback (most recent call last):
File "plotcount.py", line 8, in <module>
from wordcount import load_word_counts
File "/Users/tiffanytimbers/Desktop/make-lesson/wordcount.py", line 79
return sorted(counts.iteritems(), key=lambda (key,value): value, \
^
SyntaxError: invalid syntax
These go away when you convert the scripts to python 3 with 2to3. Looking
in the repo, I see that there are updated copies of these scripts in the
code directory where they have been converted to python 3, but this was not
obvious and is not clearly documented anywhere.
Cheers,
Tiffany
