{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Deprecate is_string_like","articleBody":"This issue is similar to #7795 (\"is_numlike should be deprecated and replaced by the correct isinstance calls\"): `cbook.is_string_like` returns True for 0-dimensional masked arrays of string dtype (but not regular arrays...), but testing for `is_string_like` is often followed by calling of string methods (`.lower()`, etc.) on the object, or passing the object to, say, `open()` -- neither of which work with masked arrays of string dtype.  (check yourself with `git grep -A2 'is_string_like('`)\r\n\r\nIn other words the actual semantics of the function simply do not match how it is used.\r\n\r\nMost of these calls should probably be replaced by `isinstance(obj, six.string_types)` (possibly `isinstance(obj, (six.string_types, six.binary_type))` depending on the case), which is much more explicit.","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2017-01-15T09:10:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/7835/matplotlib/issues/7835"}
