[issue43932] f-string decimal has leading space

[Mark Dickinson]

Mark Dickinson  added the comment:

This is by design, and documented under the "sign" section here: 
https://docs.python.org/3/library/string.html#format-specification-mini-language

The space before ".2f" is an instruction to leave space for a sign, "-" for a 
negative number and " " for a positive number. To avoid that space, use a 
format of ".2f" instead of " .2f".

>>> format(15, ".2f")
'15.00'
>>> format(15, " .2f")
' 15.00'
>>> format(15, "+.2f")
'+15.00'
