New submission from Anselm Kiefner:
Considering that
x = 3
f"{'hello' if x == 3 else 'goodbye'} world"
is a simple, elegant and powerful piece of code that works just as expected by
itself, I often find myself stumbling and wondering why
f"text {'\n' if x == 3 else ''} text"
fails horribly just because of the \ within the extra quoted string that must
be worked around with ugly code like
nl = "\n"
f"text {nl if x==3 else ''} text"
which really doesn't feel like python at all.
I am aware that the specification for f-strings says "no \ in expressions", but
please consider that in this case, the \ is not really part of the expression
but rather part of a string that isn't evaluated as part of the expression,
which might just as well be referenced to by a variable.
