As often with Python, the simplest thing to do is to fire a Python
shell and explore the problem:
>>> from django import template
>>> c = template.Context(dict(foo='foo', bar=range(3), baaz=dict(un=1, deux=2)))
>>> c
[{'baaz': {'un': 1, 'deux': 2}, 'foo': 'foo', 'bar': [0, 1, 2]}]
>>> template.Variable('foo').resolve(c)
'foo'
>>> template.Variable('bar').resolve(c)
[0, 1, 2]
>>> template.Variable('bar.0').resolve(c)
0
>>> template.Variable('baaz.un').resolve(c)
1
>>> template.Variable('50').resolve(c)
50
>>> template.Variable('"string"').resolve(c)
'string'
>>> template.Variable('\'string\'').resolve(c)
'string'
>>>
