[web2py] Issue with defaultdict(list)

2018-03-11 Thread Val K
Hi! 
If you're Windows user  it's requires to run web2py from source (not 
web2py.exe) to get modules that are installed on your machine

[web2py] Issue with defaultdict(list)

2018-03-11 Thread Drew Howell
I seem to be having issues getting defaultdict to work within Web2Py. I am 
using Web2Py version 2.16.1 (Python 2.7.11).

Here is the code in my controller:
from collections import defaultdict
g = defaultdict(list)
g['someKey'].append('someValue')

Here is the error I'm getting:

File "D:/web2py/applications/fpr/controllers/students.py" 
, line 
14, in view
 g['someKey'].append('someValue')
AttributeError: 'dict' object has no attribute 'append'

If I do the same thing in the Python Interpreter, I don't seem to get the issue.

>>> from collections import defaultdict
>>> g = defaultdict(list)
>>> g['k'].append('v')
>>> print g['k']
['v']

Am I implementing this wrong or is there some sort of issue with using 
defaultdict(list) in Web2Py?
