Perhaps I'm missing something here but this behavior seems unexpected to me. "Lists
The items of a list are arbitrary Python objects. Lists are formed by placing a *comma-separated* list of expressions in square brackets. (Note that there are no special cases needed to form lists of length 0 or 1.)"
>>> import sys
>>> print(sys.version)
3.7.3 (default, Jul 25 2020, 13:03:44)
[GCC 8.3.0]
>>> test = [ "foo" "bar" ]
>>> type(test)
<class 'list'>
>>> print(test)
['foobar']
>>> import json
>>> json.dumps({ "foo": test })
'{"foo": ["foobar"]}'
>>>
In a complex dict structure this is an easy way to shoot yourself in the foot.

This is by design. It's not really to do with lists, but to do with placing two string literals next to each other. See: https://docs.python.org/3/reference/lexical_analysis.html#string-literal-concatenation See also https://www.python.org/dev/peps/pep-3126/ . I'll close here. |
