Fix invalid format string in set_xticklabels error message.#31758
Merged
Conversation
"=" happens to be a valid format string for numeric values, but not for arbitrary objects, so an error (`TypeError: unsupported format string passed to <objecttype>.__format__`) would previously occur *while formatting the error message* for something like `set_xticklabels(object())`. (The actual case where I saw this happen is when I wrongly passed a Formatter to set_xticklabels.) Also remove a fairly pointless comment.
