Python 3's F-Strings: An Improved String Formatting Syntax

As the sibling comment points out, it actually doesn't work that way. The first parameter is only treated as a format string _if_ there are arguments. If not, it is treated as a literal string: https://github.com/python/cpython/blob/dcea78ff53d02733ac598...

I stand corrected. Thanks.

(That's what I get for assuming consistent behavior :P)

I only found out about this quirk a few months ago immediately after I had given the same warning you had to someone else. It's extremely unintuitive.
