I believe I've found a bug in the `re` module -- specifically, in the 3.7+ support for splitting on zero-width patterns. Compare Java's behavior...
jshell> "1211".split("(?<=(\\d))(?!\\1)(?=\\d)");
$1 ==> String[3] { "1", "2", "11" }
...with Python's:
>>> re.split(r'(?<=(\d))(?!\1)(?=\d)', '1211')
['1', '1', '2', '2', '11']
(The pattern itself is pretty straightforward in design, but regex syntax can cloud things, so to be totally clear: it finds any point that follows a digit and precedes a *different* digit.)
* Tested on 3.7.1 win10 and 3.7.0 linux. |
