How to write a Python f-string with the “plus and minus” symbol in a single line?

Question

The unicode for the plus and minus symbol (±) is u"\±" . I can't seem to be able to write submit this unicode with f-string in a single line. See below.

>>> print( f'{u"\u00B1"}2 stddev' )
SyntaxError: f-string expression part cannot include a backslash

Instead, I have to do this:

>>> plusminus = u"\u00B1"
>>> print( f'{plusminus}2 stddev' )
±2 stddev

I would like to write it in a single line. How do I do this with f-string?

For non f-string, I can do this:

>>> print( '\u00B12 stddev' )
±2 stddev

Answer 1

这会做
print( f'\±2 stddev' )
